The operation will be conducted 4 times in 24 hours with total magazine at least 20 units. Each operation takes about 3 hours. Bear in mind that the fishing operation is depends on the weather condition, safety in operating and landings. Fishing Depth Usually, 95-180 metres is the preferred depth for longline fishing. Fishing ground depends on the seabed condition, such as rocky, muddy, sandy and seagrass areas are desired. As a reminder, the artificial reef area shall be avoided as it is a conservation area. Shooting The shooting operation will be conducted in1 hour for 5 kilometre per operation. The fishing depth will increase with the increasing number of magazine used. Boat Speed/Direction Boat speed shall remain consistent during shooting at 1-2 knot. During hauling, the speed shall be decelerated to 1.5 knot. Type of Bait Bait can be minced or used as a whole. Bait type is usually barracuda size 20-22 cm long or squid, cut into pieces, hooked and placed in boxes. The bait- hooking process is automatically performed by the ABLL itself as the boat move forward. As the boat arrives at a desired fishing area, the flagpole will be tossed out into the sea as a starting fishing position indicator. Consequently, a sinker will be thrown out to the sea, followed by a sets of hooks until the end of the magazine, where another sinker is attached. Recording of Start Shooting Time The time when any part of the gear reaches the sea. Data Recording for Location Surveys The data and location are both recorded as below: • Record position for each station using Global Positioning System • Record position and start and stop times for shooting • Record position and start and stop times for hauling Target Species Target species are the demersal fishes from the family Carangidae, Serranidae, Lutjanidae and Nemipteridae and a small amount of pelagic fishes. The Recording of Finish Hauling Time The time when the operator hauled all part of gear on-board. Setting distance shall be calculated from position of start shooting and finish shooting compare with length of mainline deployed. Recording of Finish Shooting Time The time when the last part of the gear shot overboard. Recording of Start Hauling Time The time when operator hauled any part of gear on- board. Water inlet system will be set off and flows into the baiter to prevent line entangling. ABLL full body assemble and ready for fishing operation. Recording of Fishing Position Fishing position shall be recorded by using the GPS or an equally accurate navigation system. Position recording will be in Latitude and Longitude format. Gear malfunction Malfunctioning of fishing gear usually due to the disconnected rope or entangling of mainline under water during hauling operation. The details of entangling of longline shall be detected using floats that connected to the mainline of the longline. The position and station numbers shall be recorded. Recording of Start Fishing Position The position that any part of the gear reaches the sea. Recording of Finish Fishing Position The position that last part of the gear shot overboard. ABLL is a kind of stationary and long fishing gear, so that information of start hauling position and finish hauling position are required. Then the hooks will move one after another as the boat moves forward and the fishing operation starts. The baits will be deposited into the empty baiter together with water.
