     DETAILED DESCRIPTION 
     Various embodiments described herein are directed to a device to reduce recreational and commercial fishing gear entanglements. Entanglement is a threat particularly to humpback whales, grey whales, and blue whales on the West Coast. All of these species are protected under the Marine Mammal Protection Act, with blue whales listed as endangered, and humpback whales on the West Coast listed as threatened under the Endangered Species Act. 
     Current fishing technologies are a significant risk to large whales within the U.S. EEZ and globally. On the worldwide scale, entanglements have been documented to be a chronic problem in a broad range of previous studies. NOAA&#39;s National Report on Large Whale Entanglements (2017) for U.S. coastal waters reported that in 2017, 76 confirmed cases of large whale entanglements were documented along the coasts of the United States with 70 involving live animals and six associated with dead animals, and that the five most frequently entangled large whale species were humpback whales, gray whales, minke whales, blue whales, and North Atlantic right whales. Geographically, more than 50% of all entanglement reports occurred in California (32.9%) and Massachusetts (26.6%) waters. On the east coast of the U.S. much of the focus on whale entanglement issues has been with the North Atlantic right whale population due to the combination of its endangered status, the strong overlap between whales and fisheries, and the significant number of mortalities relative to sustainability of the population. 
     Entanglement rates on the West Coast alone are significant and have increased to a level that is comparable to the U.S. Northeast and Mid-Atlantic. The recent NOAA 2017 West Coast Entanglement Summary indicated that a total of 31 whales were entangled off the coasts of Washington, Oregon, and California with gear from U.S. fisheries. Humpback whales were the most common species entangled ( 16 ) along with gray whales ( 12 ) followed by blue whales ( 3 ). Two of the confirmed gray whale entanglements involved whales that were found dead. Entanglements were predominantly off the California coast ( 31 ) with gray whale entanglements most common in southern California, while humpback entanglements most common off central California. 
     The inherent challenge in the development of a viable rope-less fishing system is to reduce or minimize entanglement risk to marine animals such as whales without significantly impacting the viability of the fishery. 
     Most of the current research toward rope-less fishing technology has focused on adapting devices that were originally developed for retrieval of oceanographic instrumentation, which is generally very expensive, and the retrieval frequency is very low. As a result, retrieval equipment for such instrumentation is relatively expensive, complex, and cumbersome. The exact opposite is the case for some embodiments described herein. In various embodiments, costs for the equipment is reasonable, retrieval frequency is high, and complexity of implementation is reasonably low (complexity that slows down the fishing operation is very detrimental to the economics of fishing). 
     Some embodiments described herein reduces or eliminates exposure of whales to entanglement hazards in the water column. Some embodiments may be simple enough to be easily integrated into the existing fishing process without undue impact to the time and effort required to deploy and retrieve the fishing gear. The apparatus, in some embodiments, may be easily stowed within the footprint of the existing trap and does not impede the stacking of traps. Further, some embodiments provide comparable visibility on the surface to the traditional system. The system may integrate a means to determine the location and identification of the gear by fishermen and enforcement agencies in the absence of surface buoys. 
       FIGS.  1 A and  1 B  include a series of images depicting the deployment of the rope-less fishery trap (i.e., an aquatic trap) according to some embodiments. In various embodiments, the system and process of use is simple enough to be integrated into the existing fishing process without undue impact on the time and effort required to deploy and retrieve the fishing gear. The system may also be stowed within the footprint of the existing aquatic trap and may not impede the stacking of traps. Some systems described herein are reliable and redundant to the degree that the amount of equipment loss is either the same or less relative to rope-based systems of the prior art. The system may also reduce or eliminate exposure of whales to entanglement hazards in a water column. 
     An aquatic trap is a trap that is used to capture fish, lobsters, crab, or the like, usually for the purposes of commercial fishing and sea food. It will be appreciated that various embodiments described herein may be utilized with many different types of traps for sea life. 
       FIG.  1 A  depicts deployment of an aquatic trap with its trap line and buoy restrained by a line restraining system in some embodiments. The line restraining system may include a line restraint device as discussed herein. The line restraint device may be coupled to each aquatic trap. The line restraint device may restrain the trap line and buoy from extending through the water column until a pre-programmed time. At the pre-programmed time, the line restraint device may trigger a release of the trap line (e.g., rope) and buoy from the aquatic trap, thereby allowing the buoy to rise through the water column with the trailing trap line and emerge at the surface of the water. The user may then retrieve the aquatic trap in the traditional manner. 
     In step  102 , the user may set the line restraint system and line restraint device. The line restraint system may restrain all or part of the trap line to the aquatic trap. The trap is coupled to the trap line. The other end of the trap line is coupled to at least one float or buoy. 
     The trap line may be coiled and then the coiled trap line may be restrained to the outside of the aquatic trap. In one example, the coiled trap line may be held against uncoiling underwater by a release line coupled to the line restraint device. The line restraint system may include one or more restraining members (e.g., one or more bars or elongated members) connected by one end to the aquatic trap. In some embodiments, the other end of the restraining member(s) may be coupled to one end of the release line. The other end of the release line may be coupled to the line restraint device to hold the coiled trap line from uncoiling and prevent the buoy from floating to the surface. 
     In step  104 , the user may configure the line restraint device to open or otherwise disengage with one end of the release line at a programmed time (e.g., the pop-up time). The pop-up time is the time that the line restraint device is programmed to trigger release of the trap line and buoy. In various embodiments, the line restraint device includes a timer that may be set to trigger release of the trap line and buoy. The line restraint device may include a timer-release that is preprogrammed so that the buoy may pop up out of the water just before the next visit, thus minimizing exposure and risk for entanglement of nearby whales. 
     After the trap line is coiled, the trap line is positioned to be held at the aquatic trap (at least in part) by the release line, and the line restraint device is set, the user may deploy the aquatic trap. The user may drop off the trap into the water, after which the aquatic trap will sink, taking the coiled trap line and the buoy restrained at or near the aquatic trap by the line restraint device. 
     In various embodiments, the trap line may be coiled on top of the aquatic trap and held in place by a line restraint system (e.g., including one or more restraining members or a release line). The line restraint device may include a hook or lever configured to secure the line restraint system by hooking onto a release line that holds the line restraint system in place. At a pre-programmed time, the line restraint device may pivot the hook or lever to release the release line (e.g., loosening or opening the line restraint system), thereby allowing the buoy to float to the surface and uncoil all or part of the trap line on top of the aquatic trap. The line restraint device and the line restraint system are further discussed herein. 
     The user may deploy any number of aquatic traps, each aquatic trap may include a coiled trap line restrained to the respective aquatic trap and held in place, at least in party, by the line restraint device. Each line restraint device may be programmed to release the line of different aquatic traps simultaneously, near simultaneously, serially, and/or the like. In some embodiments, where there are multiple aquatic traps connected together (e.g., in a “trawl line”), a single line restraint system may be used to retrieve any number of the line of aquatic traps. 
       FIG.  1 B  depicts retrieval of an aquatic trap with its trap line and buoy released by a line restraining system in some embodiments. In step  108 , at a particular time, the line restraint device may disengage with the end of the release line, thereby enabling the buoy to float to the surface and pull the trap line from the aquatic trap. In another example, the release line may restrain the coiled trap line by wrapping one or more parts of the coiled trap line to the outside of the trap. When the line restraint device disengages with one end of the release line, the buoy floats towards the surface of the water and pulls the trap line away from the aquatic trap. The release line may fully or partially unfurl or unravel to enable all or part of the trap line to uncoil and allow one end of the trap line to be pulled up to the surface of the water by the buoy. 
     In step  110 , the user may retrieve the aquatic trap using traditional techniques. For example, the trap line of the aquatic trap may be caught by the user and connected to a winch that can pull the rope and guide the trap to the boat. Fish in the trap may be retrieved, let go, or the like. In some embodiments, the winch may include an automated line coiler that coils the trap line as the aquatic trap is hauled into the boat by the winch. After being hauled in, the aquatic trap may be re-deployed with the coiled trap line. 
     In step  112 , the aquatic trap may be re-deployed. In one example, the trap line may be coiled after retrieval (or is coiled during retrieval). The coiled trap line may be coupled to the aquatic trap with the release line. One end of the release line may be coupled to the line restraint device and the line restraint device configured to hold the line restraint device in order to restrain the coiled trap line and buoy. The user may then drop the trap back into the water. 
     Alternately, the user may coil the trap line and place the line within the aquatic trap. The aquatic trap may be stacked or positioned for storage. In some embodiments, the line restraint device may be connected to a part of the aquatic trap from within the aquatic trap itself, thereby enabling easy storage for the aquatic trap (e.g., the line restraint device may not interfere with stacking of storage of one or more aquatic traps). 
     There may be additional steps. For example, the user may optionally scan the trap. In various embodiments, the line restraint device includes a bar code, active identifier, or passive identifier that may be scanned to help identify the aquatic trap and/or the coupled line restraint device. The user may track which traps and/or line restraint devices are deployed, when they are deployed, and/or where they are deployed. In various embodiments, the line restraint device may include a sensor, tag, acoustic transceiver, and/or the like that enables the device to report a unique identifier and/or location to the user and/or a geolocation system. 
     The line restraint device and/or the user may provide a position of the trap and/or coupled line restraint device to a geolocation system using a satellite or cell link. In various embodiments, the line restraint device may include an acoustic transceiver configured to provide location information or enable the line restraint device to be located (e.g., through triangulation, strength of signal, and/or other methods). The user (e.g., fisherman) may utilize equipment aboard the ship or boat to receive signals from the line restraint device and then then user may update the location and/or identifier to the geolocation system using the satellite or cell link. In some embodiments, the line restraint device may communicate directly with the geolocation system to report its identification and/or location. The user and/or appropriate authorities may utilize information within the geolocation system to locate, log, and/or track any number of aquatic traps. 
     In some embodiments, the rope-less trap may include an acoustic tag capable of providing a rope-less trap identifier (for identification) and/or location information. For example, the acoustic tag may be or include a transceiver (e.g., within the line restraint device) that provides a signal (e.g., low frequency) that can be received by a user or enforcement agency on a boat. Each rope-less trap may include a different acoustic tag capable of providing a different identifier so each rope-less trap can be identified, even if the buoy is not deployed. 
       FIG.  2 A  depicts a first three-dimensional (3D) rendering of a line restraint device  200  in some embodiments. The line restraint device  200  may be cylindrical in shape with an end cap  204  on one end opposite the end plug  206  and release cam  208  at the other end of the line restraint device  200 . While a cylindrical shaped device is depicted as being the line restraint device  200 , it will be appreciated that the line restraint device  200  may be any shape, including square, circular, rectangular, polygonal, or the like. 
     In the example depicted in  FIG.  2 A , the line restraint device  200  may include a housing  202 , an end cap  204 , an end plug  206 , a release cam  208 , and a release line retainer  210 . The housing  202  may contain a motor as well as a timer device. 
     The line restraint device  200  may be coupled to the aquatic trap through any means, including with metal hooks, bindings, or the like. In various embodiments, the line restraint device  200  is coupled to the inside of the aquatic trap. In other embodiments, the line restraint device  200  may be coupled to the outside of the aquatic trap. 
     The release cam  208  may form or assist in forming a cavity to hold the release line. The release line retainer  210  may keep the release line from slipping out from underneath the arm of the release cam  208 . The release line retainer  210  may be affixed to the housing  202  and/or the end plug  206 . In various embodiments, the release line retainer  210  includes an outer surface and an inner surface. The inner surface may be partially coupled to the line restraint device  200  (e.g., through or by the housing  202  and/or the end plug  206 ). The inner surface of the release line retainer  210  may extend beyond the end plug  206 . When the release cam  208  is in a closed position, the face of the arm of the release cam  208  (further discussed herein) may be directed towards the inner surface of the release line retainer  210 . This may form a cavity or hole through which the release line may be looped and retained when the release cam  208  is in the closed position or state. When the release cam  208  turns to the open position or state, the arm and face of the arm turn away from the inner surface of the release line retainer  210  to create an opening in the cavity and allow the release line to escape. 
     When set (e.g., the release cam  208  is in the closed state), the release line be coupled, retained, or held by the release cam  208  and/or the release line retainer  210 . The release line holds or assists in holding the trap line in place. In various embodiments, the release cam  208  is coupled to the motor within the housing  202 . At a preprogrammed time, the motor may turn the release cam  208  such that the release cam  208  is no longer touching or directed to the release line retainer  210 . The release line will slide out from underneath the restraining member of the release cam  208  thereby allowing the float or buoy to float to the surface. 
     The release cam may include a first end that may be coupled to the motor within the housing  202 , and an arm portion that is directed away from (e.g., perpendicular or substantially perpendicular) the stem end of the release cam  208 . The arm may have a face which is a flat or curved end that can face the release line retainer  210  when the release cam  208  is in the closed state. 
     An outer surface of the release cam  208  that is opposite the stem end coupled to the motor may have a tapered section (e.g., tapered at a 45-degree angle) to assist in allowing the release line to slide away from the line restraint device  200  when the motor turns the arm of the release cam  208  away from the line restraint device  200 . In other words, the beveled section (e.g., tapered section) may assist the release line (e.g., release line  302 ) to easily slip off the release cam  208  when the release cam  208  turns. The tapered section may be beveled or tapered at any degree of angle. 
     In various embodiments, the release cam  208  and/or release line retainer  210  form a cavity (e.g., hole) for holding and restraining a loop of the release line. When the release cam  208  rotates, the release line is released from the cavity. 
     The housing  202  may include a display screen, a motor, a processor, and a controls for setting the timer. The display screen may appear through or within the housing  202 . The processor may include memory with instructions capable of setting a release time. The release time may indicate a time of day or duration (e.g., a timer). When the release time is reached, the processor will trigger the motor to turn the release cam  208  which will release the release line. 
     The end cap  204  and the end plug  206  provide protection and may seal the housing against water intrusion, even when the line restraint device  200  is on the sea floor. 
       FIG.  2 B  depicts a second three-dimensional (3D) rendering of a line restraint device  200  in some embodiments. The line restraint device  200  may be coupled to the aquatic trap through any means, including with metal hooks, bindings, or the like. In various embodiments, the line restraint device  200  is coupled to the inside of the aquatic trap. In other embodiments, the line restraint device  200  may be coupled to the outside of the aquatic trap. 
     The line restraint device  200  may include the housing  202 , the end cap  204 , the end plug  206 , the release cam  208 , the release line retainer  210 , and the cam tool socket  212 . The release cam  208  includes the tapered portion  216 . The release line cavity  214  is formed by the release cam  208  and the release line retainer  210  when the line restraint device  200  is in the closed state.  FIG.  2 B  also includes an end plug view  218 . 
     The release cam  208  may form or assist in forming a cavity (i.e., the release line cavity  214 ) to hold the release line. The release line cavity  214  may be hole or a divot within sold material. The release cam  208  may comprise one or more portions that include a stem end and an arm. The release cam  208  may, for example, form an “L” shape in which the stem end extends from the end plug  206  and the arm forms a bend with the stem end. The arm extends outwards away from the central axis of the stem end (e.g., the central axis being a longitudinal access extending through the line restraint device  200 ). The stem end may extend from an end of the housing  202 . 
     The stem end may be coupled to the motor or coupled to an axel that is coupled to the motor within the housing  202 . In some embodiments, the stem end is positioned at one end of the housing along a longitudinal, radial axis that runs through the middle of line restraint device  200  down the length of the device from end to end (e.g., from end plug  206  to end cap  204 ). 
     The release line retainer  210  may keep a loop of the release line from slipping out from underneath the arm of the release cam  208 . The release line retainer  210  may be affixed to the housing  202  and/or the end plug  206 . In various embodiments, the release line retainer  210  includes an outer surface and an inner surface. The inner surface may be partially coupled to the line restraint device  200  (e.g., through or by the housing  202  and/or the end plug  206 ). The inner surface of the release line retainer  210  may extend beyond the end plug  206 . When the release cam  208  is in a closed position, a face of the arm of the release cam  208  (further discussed herein) may be directed towards the inner surface of the release line retainer  210 . This may assist to form a cavity or hole through which the release line may be looped and retained when the release cam  208  is in the closed position or state. When the release cam  208  turns to the open position or state, the arm and face of the arm turn away from the inner surface of the release line retainer  210  to create an opening in the cavity and allow the release line to escape. 
     Opposite the stem end, the release cam  208  may include an arm portion. The arm portion may extend away from the longitudinal, radial axis. 
     As discussed herein, the release cam  208  may form a hook or lever to create the release line cavity  214  in order to hold or trap the release line (e.g., with a loop of the release line in the release line cavity  214  until the release cam  208  turns). The release line retainer  210  may keep the release line from slipping over the release cam  208  when the release cam  208  is in the closed position. 
     The release cam  208  may include a tapered portion  216  to assist the release line to be freed from the release line cavity  214  when the release cam  208  is in or progressing to the open state. The tapered portion  216  may be at any angle. In some embodiments, there is no tapered portions  216 . 
     In various embodiments, the release cam  208  is coupled to the motor within the housing  202 . At a preprogrammed time, the motor may turn the release cam  208  such that the release cam  208  is no longer touching or directed to the release line retainer  210  (e.g., opening the release line cavity  214  such that the release line may be freed from the line restraint device  200 . 
     The release cam may include a first end that may be coupled to the motor within the housing  202 , and a lever portion that is perpendicular (or substantially perpendicular) to the end of the housing  202 . An outer end of the release cam  208  that is across from the first end coupled to the motor may have a tapered section (e.g., the tapered portion  216 ) to assist in allowing the release line from sliding away from the line restraint device  200  when the release cam  208  turns away from the line restraint device  200 . 
     As discussed herein, the housing  202  may include a display screen, a motor, a processor, and controls for setting the timer. The display screen may appear through or within the housing  202 . The processor may include memory with instructions capable of setting a release time. The release time may indicate a time of day or duration (e.g., a timer). When the release time is reached, the processor will trigger the motor to turn the release cam  208  which will release the release line. 
     The end cap  204  and the end plug  206  provide protection and may seal the housing  202  against water intrusion, even when the line restraint device  200  is on the sea floor. The end plug  206  may also seal the housing  202 . The end plug may be coupled to the housing  202 . The release cam  208  may be coupled to the motor within the housing  202  through the end plug  206 . 
     The release cam  208  may include a cam tool socket  212 . A cam tool may include an end that can be coupled through the cam tool socket  212  to optionally set the timer. In some embodiments, the timer is set by turning the release cam  208  as discussed herein. In some embodiments, the cam tool may be used to release the end plug  206  from the housing  202 . 
     In various embodiments, the housing  202  includes a processor and memory configured to be able to set a pop-up time. In various embodiments, the pop-up time may be configured by turning the release cam  208  prior to deployment of the aquatic trap. For example, twisting the release cam  208  in one direction may enable the pop-up time to be set. Example processes of setting the pop-up time is discussed herein. 
       FIG.  3 A  depicts a line restraint device  200  in some embodiments. The line restraint system  300  may include the line restraint device  200 , the release line  302 , and retain member(s)  304 . The retain member(s)  304  may include a single retention member  304 , two retain members  304 , or more. in one example, the retention member  304  may be “V” shape. Each end of the “V” shape may be coupled to the outside of an aquatic trap (e.g., through rings, hooks, rope, and/or otherwise). One point of the retention member  304  may be coupled to an end or portion of the release line  302 . 
     The trap line may be coiled and all or of the trap line positioned underneath all or part of the retention member(s)  304 . Similarly, all or part of the coiled trap line may be positioned underneath at least part of the release line  302 . 
     Two ends of the release line  302  may be coupled to the retention member(s)  304  to form a loop. The other end of the loop of the release line  302  may be coupled to the release cam  208  of the line restraint device  200 . In one example, the loop of the release line  302  may be looped around the release cam  208  and prevented from escaping by the release line retainer  210 . In other example, one end of the release line may be coupled to the retention member(s)  304  and the other tied to form a loop or otherwise releasably tied or looped around the release cam  208 . 
     There may be any number of retention members  304 . In some embodiments, each retention member  304  may form a separate leg where one end of each retention member is coupled to the aquatic trap and the other end coupled or otherwise held in place by the release line  302 . When the line restraint device  200  releases one end of the release line  302 , the float or buoy will pull and uncoil the trap line. The pressure from the buoy will force the trap line to escape the loose and/or open retention members  304  and/or remaining release line  302 . 
       FIG.  3 B  depicts a circular aquatic trap  306  (e.g., a Dungeness crab pot) with the line restraint device  200  in some embodiments. In this example, the trap line  406  (discussed herein) may be coiled and secured to the top of the aquatic trap  502  using the release line  302  (e.g., a bungee loop) and the timed release of the line restraint device  200 . Each of the retention members  304  is separately coupled to an edge of the aquatic trap  306 . It will be appreciated that the retention members  304  may be coupled to any portion of the aquatic trap  306 . The retention members  304  as depicted in  FIG.  3 B  are on the outside of the aquatic trap  306 . Each end of the retention members  304  that are coupled to the aquatic trap  306  may be coupled to the aquatic trap with locking member  308  which may be a ring, strap, or other connector. 
     In this example, the release line  302  extends from the line restraint device  200 , through a loop (e.g., D ring  312 ) in the center of the aquatic trap  306 , and then to the retention member(s)  304 . The D ring  312  may be coupled to the aquatic trap  306  and the release line  302  may be wrapped around the ring (e.g., with one winding or one wrap around a part of the ring). The optional D ring  312  may serve to secure the coiled trap line  406 . When the release line  302  is released from the line restraint device  200 , the release line  302  may be pulled from all or part of the D ring  312  by the force of the trap line  406  being pulled by the buoy is it floats towards the surface. 
     Similarly, the line restraint device  200  may be coupled to the aquatic trap by one or more device locks  310 . The device locks  310  may include one or more metal rings or bands configured to hold the line restraint device  200  to a portion of the aquatic trap  306  (e.g., inside the aquatic trap  306 ). It will be appreciated that the line restraint device  200  may be held to the aquatic trap  306  in any number of ways (e.g., using rope, a bracket, rings, straps, and/or the like). 
       FIG.  3 C  depicts a close view of the circular aquatic trap  306  with the line restraint device  200  in some embodiments. In this figure, the release line  302  extends from the line restraint device  200  over the coiled tap line. The line restraint device  200  includes a cavity  318  formed, in part, by the arm  314  of the release cam  208 . The release line  302  extends from the coiled trap line through the cavity  318 . One portion of the arm  314  includes the beveled portion  316  which may assist the release line  302  from being freed from the cavity  318  when the motor in the line restraint device  200  turns the arm  314 . 
       FIG.  4    depicts an image of the aquatic trap installed in a black sea bass trap according to some embodiments. In this example, there may not be retention members  304 . The trap line  406  is coiled to the outside of the bass trap and held in place by looping the release line  302  around two sides of the coiled trap line  406 . Two ends of the release line  302  may be tied or otherwise secured to the bass trap while a loop of the release line  302  may be wrapped around the release cam  208  of the line restraint device  200  (e.g., through a cavity that is created when the release cam  208  is in the closed position). In  FIG.  4   , the release cam  208  is in the “open” position thereby allowing the loop of the release line  302  to be placed in a cavity that will be defined by the release cam  208 , the release line retainer  210 , and the end cap  204  when the release cam  208  is turned to a “closed” position. 
     After the bass trap is deployed, a timer when trigger the motor to turn the release cam  208  to the open position and release the loop of the release line  302  thereby allowing the buoy  404  to float to the surface. The buoy  404  is coupled to one end of the trap line  406  and, when the release line  302  is released from the line restraint device  200 , will pull the trap line  406  such that the release line  302  may further unfurl or unravel from being around the coiled trap line thereby allowing all or part of the trap line  406  to extend. 
     It will be appreciated that the release line  302  may be coupled to the aquatic trap and the line restraint device  200  in many different ways. In various embodiments, the release line  302  forms a loop that is hooked around the release cam  208 . Once the loop escapes from the line restraint device  200  (due to the movement of the release cam  208 ), the coiled trap line  406  is free to be pulled by the buoy  404 . When the line restraint device  200  is in the closed state the release line  302  is held in place and the buoy  404 , tied to the trap line  406 , is unable to rise. 
     It will be appreciated that it may be preferable use to alternative methods to retain the trap line  406  until the line restraint device  200  releases the release line  302 . In some embodiments, only the release line  302  holds part of the coiled trap line  406  while in other embodiments, part of the coiled trap line  406  may be held in place by retaining members or the like. 
       FIG.  5    depicts an image of the line restraint device installed on a lobster trap in some embodiments. As used herein, the term aquatic trap may refer to any trap for sea animals. In this image, the buoy  504  is tied t the trap line  506 . The trap line is coiled and restrained by the release line  302  and the retention member  304 . The retention member  304  is in a “V” configuration where the ends are connected to the aquatic trap  502  my connectors, such as rings. The center of the retention member  304  is tied or looped with the release line  302 . The ends of the release line  302  may be tied to the aquatic trap  502 . A loop of the release line  302  may be looped around the retention member  304 , a coil of the trap line  506 , and through the line restraint device  200  (e.g., underneath the release cam  208  when the release cam  208  is in the closed state. 
     The coil of the trap line  506  may be around the center of the retention member  304 . The coil of the trap line  506  may be placed between the aquatic trap  502  and the retention member  304  to keep the trap line  506  from being pulled free by the buoy  504 . Further, the coil of the trap line  506  may be constrained between the release line  302  and the aquatic trap  502 . 
     When the release cam  208  rotates to the open state, the release line  302  may be released from the line restraint device  200  thereby freeing the release line  302  from be constrained between the release line  302  and the aquatic trap  502 . Further, the release of the release line  302 , may allow the coil to pull always from being between the retention member  304  and the aquatic trap  502 . In some embodiments, when the release line  302  is released, the retention member  304  may loosen or open to further allow the trap line  506  to pull free. It will be appreciated that although the trap line  506  is no longer constrained by the release cam  208  and the retention member  304 , one end of the trap line  506  remains tied to or otherwise connected to the aquatic trap  502 . 
     While a single retention member  304  is discussed regarding  FIG.  5   , it will be appreciated that there may be any number of retention members  304 . For example, each end of the retention member  304  extending from the center outwards may be a separate member. 
     In various embodiments, the release line  302  may be coupled to a twine or other material. The twine or other material may be, for example, degradable cotton. In one example, the release line  302  is coupled to a degradable cotton twine and the degradable cotton twine is coupled to the line restraint device  200  (e.g., through release cam  208 ). The degradable cotton twine may degrade underwater over a period of time. The period of time may be longer than the time set at the timer. In various embodiments, the degradable cotton twine may degrade and release the release line  302  and/or the trap line  406 . In one example, the degradable cotton twine or other degradable material may provide a back up system to release the buoy and trap line even if the line restraint device  200  fails (i.e., to enable retrieval of the aquatic trap, trap line, buoy, and line restraint device  200  even if the line restraint device  200  fails). 
       FIGS.  6 - 8    depict the line restraint device  200  holding and releasing the release line  302  in one example. As discussed herein the timer-release of the line restraint device  200  may be preprogrammed to trigger release of the trap line so that the buoy will pop up just before the next visit, thus reducing exposure and risk for entanglement of nearby whales. 
     For turnaround/retrieval, the float will be at the surface when the fisherman arrives and be recovered using normal handling gear. The line restraint device  200  could then be re-set, and the trap would be re-deployed. 
     At the time of deployment, the real-time geolocation system is used to mark the location of the trap and transmit that location to a database of regional trap locations. The geolocation system is also used to display the locations of other nearby traps so that interference can be avoided. For regulatory purposes, enforcement personnel could monitor trap deployments via the geolocation database. 
       FIG.  6    depicts a line restraint device  200  holding a release line  302  which holds the coiled trap line in place in some embodiments. In this figure, the aquatic trap  306  has already been deployed and is on the sea floor. The release line  302  may be, for example, a bungee cord, rope, or any other kind of line. 
     In  FIG.  6   , the release cam  208  is in the closed position where the release cam  208 , the end cap  204 , and the release line retainer  210  form a cavity that the release line  302  runs through. The release cam  208 , the end cap  204 , and the release line retainer  210  may retain or otherwise restrain the release line  302  which holds the trap line as well as the float at or near the fish cage. One end of the trap line is coupled to the float or buoy which is floating at or immediately about the aquatic trap  306 . The float or buoy is constrained from floating to the surface because the trap line is held in place at least partially by the release line  302 . 
       FIG.  7    depicts the line restraint device  200  turning the release cam  208  to release the release line  302  and free the coiled trap line in some embodiments. In  FIG.  7   , the timer of the line restraint device  200  has triggered the motor to turn (e.g., rotate) the release cam  208  which will open the cavity and release the loop of the release line  302  from the line restraint device  200 . 
       FIG.  8    depicts the line restraint device  200  in an open state in some embodiments. the release cam  208  may turn to open the cavity and release the release line  302 . The release line  302  may no longer restrain the coiled trap line when the line restraint device  200  is in the open state. Once the release line  302  escapes from the line restraint device  200 , the buoy starts to float towards the surface. The trap line then extends between the buoy and the aquatic trap to enable retrieval of the aquatic trap. 
     The trap line is depicted in  FIG.  8    as floating away from the aquatic trap as the float pull towards the surface. 
       FIG.  9    depicts a 3D rendering of interior components of the line restraint device  200  according to some embodiments. In this depiction, the housing and end cap has been removed from the line restraint device  200 . It will be appreciated that the housing, end cap, and end plug  902  may seal the inner components from getting wet when the line restraint device  200  is submerged. 
     In various embodiments, the end cap and/or the housing may be decoupled from the end plug  902 . The release line retainer  210  may be fastened to the housing in some embodiments. In various embodiments, removing the end plug  902  may allow for access to the internal parts of the line restraint device  200 . For example, removal of the end plug  902  may provide access to replace batteries and/or provide maintenance to other internal parts of the line restraint device  200 . 
     The 3D rendering of the line restraint device  200  includes the end plug  902 , the release cam  208 , end plug O-ring seal  904 , a planetary gear  906 , a motor  908 , an encoder  910 , a display  912 , a bulkhead  914 , battery  916 , control and power PCB  918 , bulkhead  920 , threaded rods for bulkhead mount  922 , access for shaft set screw  924 , and a release line retainer  210 . 
     The end plug  902  may be circular and include a hole in the center of the plug to enable the release cam  208  to be coupled with an axel that runs to the motor  908 . In various embodiments, the end plug  902  may be coupled to the release line retainer  210 . The motor  908  may be any motor. In one example, the gear reduction ratio of the motor  98  is 227:1 but any gear ratio may be used. 
     The end plug O-ring seal  904  may be coupled to or near the end plug  902 . The end plug O-ring seal  904  may assist in sealing the inner workings of the line restraint device  200  from water when the device is submerged. The end plug O-ring seal  904  may also assist in keeping the housing in place and positioned at or near the end plug  902 . 
     The planetary gear  906  may include or be a gear wheel whose axis describes a circular path around that of another wheel. 
     In various embodiments, the planetary gear  906  is a DC planetary gear brush motor, model number #638252 from Robotzone. The planetary gear  906  may assist in the setting of the timer. In various embodiments, the timer may be set when the line restraint device  200  is disarmed and the release cam  208  is twisted or turned by the user (e.g., fisherman) to set the timer. The planetary gear may allow the movement of the release cam  208  to bypass the motor  908  or enable the motor  908  to be manipulated in such a way as to allow movement of the release cam  208  to assist setting the timer. 
     Similarly, the planetary gear  906  may enable the motor to turn the release cam  208  without resetting the timer or disarming/arming the line restraint device  200 . 
     The timer may be controlled by the control and power PCB  918 . In various embodiments, the control and power PCB  918  includes a processor configured to set the timer, run the timer, and to trigger the motor  908  to open the release cam  208  from the closed state when the timer reaches a predetermined time. 
     By turning or otherwise manipulating the release cam  208 , the encoder  910  may translate or assist in translating movements of the release cam  208  to signals that can be received by the control and power PCB  918  for setting the timer, arming the line restraint device  200 , or disarming the line restraint device  200 . The process is further described herein. The encoder  910  may be coupled to the motor  908  and may assist with allowing the release cam  208  to be used as a control knob for setting the timer. 
     The display  912  may be any display. For example, the display  912  may include an LED screen. In one example, the display  912  may depict the timer setting, whether the line restraint device  200  is armed, or whether the line restraint device  200  is disarmed. The display  912  may be monochrome (e.g., red, blue, green, black, or the like) or have any number of colors. In various embodiments, the display  912  may be within a clear housing  202  of the line restraint device  200 . 
     The battery  916  may be any power source. In one example, the battery  916  includes any number of AA batteries, AAAA batteries, lithium batteries, or the like. In some embodiments, the battery  916  may power the display  912 , the control and power PCB  918  (e.g., for the timer), and/or the motor  908 . In some embodiments, the power source may include a spring/coil powered system and/or the like. 
     The line restraint device  200  depicted in  FIG.  9    has two bulkheads including bulkhead  914  and bulkhead  920 . The bulkhead  914  may provide support within the end cap not depicted. Similarly, the bulkhead  920  may provide support for the threaded rods (e.g., the bulkhead mount  922 ) which provides structural support and protection for the motor  908  and the planetary gear  906 . The bulkhead  920  also provides support and structure for the encoder  910  to assist in the setting of the timer. 
     The shaft set screw  924  may be accessible through the housing of the line restraint device  200 . Unscrewing the shaft set screw  924  may enable the housing to be removed to gain access to the inner workings of the line restraint device  200  (e.g., to change the battery  916 ). 
       FIG.  10    depicts another 3D rendering of interior components of the line restraint device  200  without the bulkhead mount  922  in some embodiments.  FIG.  10    further depicts aspects of the release cam  208  in some embodiments. The line restraint device  200  in  FIG.  10    depicts the release cam  208  as well as components of the release cam  208  including a stem portion  1002 , an arm  1004 , a face  1006 , an inner surface  1008 , and an outer surface  1010 .  FIG.  10    further depicts release cam O-ring grooves (2 places)  1012 , a motor hub  1014 , thrust washers  1016 , and motor shaft setscrew  1018 . 
     The release cam  208  may be a single piece (e.g., created from a 3D printer or machined) or include a combination of parts. The release cam  208  includes a stem  1002  which may be coupled to the motor  908  or an axel that is coupled to the motor  908 . The stem  1002  may also be coupled through the planetary gears  906  to communicate with the control and power PCB  918  to set the timer (e.g., through the encoder  910 ). The stem portion  1002  is depicted as being round but may be any shape. In some embodiments, the stem portion  1002  does not extend to the face  1006  of the release cam  208 . 
     The arm  1004  may be coupled to one of the stem portion  1002  opposite the end of the stem portion  1002  that is nearest to the motor  908  (e.g., opposite the end of the stem portion  1002  that is coupled to the motor  908  and/or axel from the motor). The arm  1004  and the stem portion  1002  may form an “L” shape. The arm  1004  may extend out from a linear, radial axis of the line restraint device  200  and may create an overhang. The arm  1004  may include a face  1006  that is the width or part of the width of the arm  1004 . The face  1006  may be flat or curved. In various embodiments, when the line restraint device  200  is in a closed state, the face  1006  may be directed towards the release line retainer  210 . The release line retainer  210  may extend from the housing of the line restraint device  200  and may touch or become proximate to the face  1006  when the release cam  208  is in the closed state. When the release cam  208  rotates to the open state, the release cam  208  may turn the arm  1004  and the face  1006  away from the release line retainer  210  to open a cavity that may hold part of the release line  302 . 
     In various embodiments, the user (e.g., the fisherman) may turn the arm  1004  to turn the release cam  208 . The user may turn the arm  1004  away from the release line retainer  210  to access the cavity (e.g., the open state) and place a loop of the release line  302  within the cavity. The user may then turn the arm  1004  toward the release line retainer  210  to close the cavity and retainer the release line  302  within the cavity. When closed, the cavity may be formed by the inner surface  2008  of the arm  1004 , a portion of the stem portion  1002  (e.g., the portion facing the release line retainer  210 ), a portion of the release line retainer  210  (e.g., the portion of the release line retainer  210  that extends beyond the housing and/or the end plug  902  and below the face  1006 ), and the surface of the end plug  902  that is opposite the motor and the rest of the inner workings of the line restraint device  200 . In the open state, the user may turn the arm  1004  to pull the face  1006  away from the release line retainer  210  to provide open access to the cavity. 
       FIG.  11    depicts a side view of the line restraint device  200  in some embodiments. The line restraint device  200  may be of any length. In this example, the total length of the line restraint device  200  may be 9.647 inches long and the end plug may be 1.550 inches long. The line restraint device  200  may be 1.670 inches in diameter. 
       FIG.  12    depicts a view of a motor mount in some embodiments. The motor mount may mount the motor to the line restraint device  200  (e.g., within the bulkhead mount  922 ). Measurements may be in inches in this example. 
       FIG.  13    depicts views of the motor end plug  206  for holding the motor in some embodiments.  FIG.  13    includes a face view  1302 , a first orientation side view  1304 , and a second orientation side view  1306 . The measurements of the motor end plug may also be in inches. 
       FIG.  14    depicts a process for setting a timer of the line restraint device  200  in some embodiments. The timer may be set without a separate programmer or disposable parts. 
     In some embodiments, the user may turn the arm  1004  to arm the line restraint device  200 , disarm the line restraint device  200  and/or the set the timer. The figures in  FIG.  14    depict a top view from the top end of the line restraint device  200 . The top end of the line restraint device  200  includes the outer surface of the arm  1004 . The red arrows depict the direction that the user may turn the arm  1004  (and turn the release cam  208 ). 
     In the first figure, the user may turn the arm  1004  in either direction until the display  912  depicts “arm/set.” It will be appreciated that the display  912  may display “set” or any information. In this example, once the display  912  indicates that the timer may be set, the user may turn or rotate the release cam  208  (by turning the arm  1004 ) until the desired time appears. The set time may include a specific time or a duration in the future (e.g., within 2 hours) when the timer will expire which will trigger the release cam  208  to rotate into he open state to release the release line  302  from the cavity. 
     In some embodiments, there line restraint device  200  may include a variety of presets, each of which may be a different time or duration in the future (e.g., 1 hour, 2 hours, 20 minutes, 40 minutes, 3 hours, four hours, five hours, six hours, seven hours, eight hours, ten hours, twelve hours, 1 day, 2 days, or the like). In one example, the user may turn the arm  1004  to select a different preset. 
     Once the desired time or preset is displayed, the user may wait a set duration (e.g., three seconds or any amount of time) to store the time. Once the time is stored, the display  912  may display “arm/set.” 
       FIG.  15    depicts a process for arming the line restraint device  200  in some embodiments. After the time is set, the user may turn the arm  1004  until the “arm display” appears in the display  912  and the arm  1004  is short of the release line retainer  210  (e.g., there is still access for the release line  302  to be placed within the cavity). The user may then place a loop of the release line  302  in the cavity and then move the arm  1004  over the loop of the release line  302  (e.g., to the closed state when the arm  1004  extends to or near the release line retainer  210  and the face  1006  of the arm  1004  faces the release line retainer  210  or a portion of the release line retainer  210 ). In some embodiments, if the arm  1004  is turned such that the face  1006  faces the release line retainer  210 , the user may wait a predetermined period of time (e.g., 10 seconds) and the display  912  may display “armed.” 
     When the line restraint device  200  is in a closed state, the arm  1004  is directed to the release line retainer  210  (e.g., the face  1006  of the arm  1004  may be directed to and/or proximate to a portion of the release line retainer  210 ). The “closed” state is the “armed” state as displayed on the display  912 . 
     It will be appreciated that to minimize programming time, the timer may automatically reset to the same time/duration as the previous deployment, or it can be quickly reprogrammed by rotating the cam (using an encoder attached to the motor). 
       FIG.  16    depicts a process for disarming the line restraint device  200  in some embodiments. After the line restraint device  200  is armed, the user may disarm the line restraint device  200  by turning the arm  1004  until the display  912  displays “disarm” or “arm/set.” By turning the arm  1004 , the release line  302  may be released from the cavity. 
     Once set and armed, the display  912  may be blank or may turn blank after a predetermined period of time. Similarly, once disarmed, after a predetermined period of time, the display  912  may turn blank. 
       FIG.  17    depicts a process for releasing the release line  302  from the cavity formed at least in part by the release cam  208  in some embodiments. In various embodiments, the timer of the line restraint device  200  may trigger the release cam  208  to move (e.g., rotate) at the pop-up time (e.g., the pop-up time being set by the user as discussed for example herein). At the time, with the line restraint device  200  already armed, the display  912  may be blank and the control and power PCB  918  may trigger the motor  908  to turn the arm  1004  to release the loop of the release line  302 . In some embodiments, when the arm  1004  is turned to release the release line  302  (e.g., the arm is turned 180 degrees), the display may optionally display “Released.” 
     The float may pull on the trap line, which is coiled and held in place, at least in part, by the release line  302 . When the release line  302  is released by the line restraint device  200 , the float may pull the trap line which may force and/or pull the release line  302  out of the cavity. In various embodiments, the release cam  208  includes a tapered portion  1702  that may incline from the arm  1004  (e.g., opposite the face  1006 ) to the opposite edge of the stem portion  1002 . The tapered portion  1702  may assist the release line  302  to pull free from the cavity and slide over all or part of the tapered portion  1702 . The tapered portion  1702  may be at any angle and may be sloped such that the part of the tapered portion  1702  closest to the arm  1004  is upward, away from the housing, and the opposite part of the tapered portion  1702  closest to the stem portion  1002  is downwards, towards the housing. 
     The following is a setup of the line restraint device  200  in one example. In step 1, the user turns on the line restraint device  200  be turning the arm  1004  and/or inserting the screwdriver and rotating the cam either direction at least 90 degrees. In step 2, when the “ARM/SET” notice displays, user may turn the arm  1004  or use the screwdriver to rotate the release cam  208  until the time displays in format DD HH.MM. The user may then rotate the arm  1004  of the release cam  208  clockwise to increase the time, or counterclockwise to decrease the time. The user may wait a predetermined period of time (e.g., 3 seconds) to be accepted by the unit and the line restraint device  200  may again display “ARM/SET.” In step 3, the user may coil the trap line  506  in a coil (e.g., with diameter of approximately 18 inches) and place the coil on top of the aquatic trap  306 . In step 4, the user may feed the release line  302  through a loop at the base of the float and then under a section of the aquatic trap  306  (e.g., within the wiring of the aquatic trap  306 ) that is in the center of the trap line  506  coil. In step 5, the user may stretch the release line  302  (e.g., a loop of the release line  302 ) over a part of the trap line  506  coil pulling the release loop of the release line  302  toward the release cam  208  of the line restraint device  200 . The user may turn the release cam  208  or use a screwdriver to rotate the release cam  208  in a direction or either direction until “ARM/SET” displays. The user may rotate the release cam  208  counterclockwise until the line restraint device  200  displays “ARM UNIT” and the release cam  208  is just about to engage with the portion of the release line retainer  210  extending from the housing of the line restraint device  200 . The user may loop the release line  302  under the release cam  208  and complete the rotation of the arm  1004  to the armed position with the release cam  208  (e.g., the arm  1004  of the release cam  208 ) pointing down towards the release line retainer  210 . After a predetermined period of time (e.g., 10 seconds), the TR4RT display may indicate “ARMED.” The line restraint device  200  may be ready to be deployed. 
     In various embodiments, a geolocation system may be utilized. An app on a smartphone, smart table, personal computer, or the like may display a map. When an aquatic trap  502  is deployed, the user may press a deploy button on the app screen and the trap, location, deployment time and/or pop-up time may be submitted to a database via cellular link. If the boat is outside of cell range, the submission can be supplemented by satellite link or the submission can be buffered and submitted when cell communication is restored. When the aquatic trap  502  is recovered, the user may press a retrieve button on the app screen and the database may be updated to indicate the time the trap had been removed. 
     The app can also be used to access trap locations from the database in the vicinity of the boat to help avoid interference. A radial distance from existing traps may be designated, and the user may be notified by the central system (e.g., in communication with the database) and/or the app via a warning on the app screen if the user is deploying too close to an existing trap location. 
     In various embodiments, the database and information identifying location and identity of the aquatic traps may be used by regulators to assist in assessing placement of traps by permit time, area, and the like. Regulators may be able to export information and perform statistical analysis to determine total traps, soak times, and the like. The information may be available to regulators and law enforcement in real-time (e.g., as soon as an aquatic trap  502  is deployed, the database may be updated and that information may be provided immediately to or at the request of regulators and/or law enforcement). 
     While many embodiments discussed herein depict the release cam  208  turning to open the cavity, it will be appreciated that any movable device or articulation may operate to open or close to hold the release line  302 . Further, in some embodiments, rather than the release cam  208  moving, any component or combination of components may move to release the release line  302 . For example, the release line retainer  210  may move (e.g., the motor may rotate the release line retainer  210  around the line restraint device  200 ) to release the release line  302 . 
       FIG.  18    is a block diagram illustrating entities of an example digital device able to read instructions from a machine-readable medium and execute those instructions in a processor to perform the machine processing tasks discussed herein, such as the engine operations discussed above. Specifically,  FIG.  18    shows a diagrammatic representation of a digital device in the example form of a digital device  1800  within which instructions  1824  (e.g., software) for causing the machine to perform any one or more of the methodologies discussed herein may be executed. In alternative embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines, for instance, via the Internet. 
     The digital device may include a processor and memory any may include a PIC, processor, raspberry PI, or the like. 
     The example digital device  1800  includes a processor  1802  (e.g., a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processor (DSP), one or more application-specific integrated circuits (ASICs), one or more radio-frequency integrated circuits (RFICs), or any combination of these), a main memory  1804 , and a static memory  1806 , which are configured to communicate with each other via a bus  1808 . The digital device  1800  may further include a graphics display unit  1810  (e.g., a plasma display panel (PDP), a liquid crystal display (LCD), a projector, or a cathode ray tube (CRT)). The digital device  1800  may also include a data store  1812  and a network interface device  1814 , which also are configured to communicate via the bus  1808 . 
     The data store  1812  includes a machine-readable medium  1816  on which is stored instructions  1818  (e.g., software) embodying any one or more of the methodologies or functions described herein. The instructions  1818  (e.g., software) may also reside, completely or at least partially, within the main memory  1804  or within the processor  1802  (e.g., within a processor&#39;s cache memory) during execution thereof by the digital device  1800 , the main memory  1804  and the processor  1802  also constituting machine-readable media. The instructions  1818  (e.g., software) may be transmitted or received over a network (not shown) via optional network interface  1814 . 
     While machine-readable medium  1816  is shown in an example embodiment to be a single medium, the term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) able to store instructions (e.g., instructions  1818 ). The term “machine-readable medium” shall also be taken to include any medium that is capable of storing instructions (e.g., instructions  1818 ) for execution by the digital device and that cause the machine to perform any one or more of the methodologies disclosed herein. The term “machine-readable medium” includes, but should not be limited to, data repositories in the form of solid-state memories, optical media, and magnetic media. 
       FIG.  19    depicts different views of the release cam  208  in an embodiments. Measurements may be in inches. Some of the views depict the step as well as clearances for coupling the step to the motor  908  and/or axel. 
     It will be appreciated that the housing  202 , end cap  204 , release cam  208 , and motor mount may, in some embodiments, be made using a 3D printer or a PW machine. The motor  908  may be a 116 RPM premium planetary gear motor with encoder (e.g., the motor  908 , planetary gear  906 , and encoder  910  maybe together). Each bulkhead  914  and  920  may be, for example, 3D print 6 g of filament per unit—HATCHBOX PLA 3D Printer Filament, Dimensional Accuracy +/−0.03 mm, 1 kg Spool, 1.75 mm.
