  MTAN ArrowHatchery Tips  Fish Culture and Resource Agencies By: MTAN The theme for this edition of the MTAN, is "For Your
    Information" (FYI). As in any profession, we are only as good as the amount of effort
    we are willing to give and the quality of information and tools we have at hand. To help
    us all gain yet another source of information and perspective, MTAN gives thanks to the
    watchful eye of Neil Kmiecik (Biological Services Director - Great Lakes Indian Fish and
    Wildlife Commission). Mr. Kmiecik informed MTAN of several additional contact agencies who
    deal with fishery resources and fish hatchery operations. The information which follows
    was published in the Aquaculture Magazine Buyers Guide '93. This guide is an
    "International" publication which reaches a broad spectrum of the fishery
    community. For the purpose of conserving space, MTAN chose to only list a portion of the
    National agencies listed. If you would like to have a more detailed listing of these
    National and International agencies, please contact MTAN or write to the Aquaculture

  Disinfection By: Dale Bast, Iron River National Fish Hatchery Pathogens are a constant threat to the intensive culture of
  fish. Whether bacteria, viral or parasitic, pathogen introduction into fish rearing
  facilities must be avoided whenever possible. One of the easiest ways to inadvertently
  introduce pathogens is through egg or fish transfers onto your facility. Next in line
  would be all the equipment that the fish or eggs come into contact with; i.e. egg shipping
  cases, dipnets, waders and distribution trucks. To prevent pathogen transfer, a standard
  disinfection policy should be established for each station. All equipment that was exposed to an outside water source should be
  considered contaminated. All contaminated materials should be isolated at a predetermined spot for disinfection. This site should be off your fish rearing area if possible. If not,
  choose a site where any dripping water cannot flow into your fish culture area or its
  water supply. Chemicals used for disinfection can be chlorine, iodine, or alcohol. Avoid
  using chlorine on electrical equipment and scientific instruments. High pressure sprayers
  work well for large equipment and distribution trucks. The high pressure also removes mud
  and debris as well as chemically treating the surface. **Sensitive Electrical Instrument Disinfection Procedure** 1. Isolate instrument in a dry area. 2. Wipe entire unit with rubbing alcohol. 3. Wipe counter top with alcohol. 4. Let dry and store.  **Fish Culture Equipment (nets, boots, brushes)** 1. Mix chemicals for disinfection. A large covered plastic waste
  receptacle works well for disinfectant storage. 2. Dip equipment and expose all surfaces to the chemical. 3. Let air dry, if possible. 4. If used immediately, rinse before introducing into fish culture
  water.  Distribution Truck 1. Park truck in isolation area. 2. Add chemical to tank and then fill with water. {A note from MTAN}
  If two or more compartments to the tank are inner connected by a sliding screen, you may
  want to first fill the tank with water, then add the chemical. This procedure will insure
  that the amount of chemical needed for each compartment will not be flushed to the lower
  end of the tank.  One gallon of household bleach (5.5% chlorine) mixed with 275
  gallons of water, produces a disinfectant solution concentration of 200 ppm chlorine. 3. Wash and disinfect truck from top to bottom, front to back. Be sure
  to also spray the inside of the discharge hoses. 4. Run all pumps or aerators. 5. Run oxygen stones. 6. Neutralize chemical (add 10 grams of sodium thiosulfate to each
  gallon of chlorine water) and drain. 7. Rinse with fresh water. 8. Let air dry. 9. Rinse tanks once more before hauling fish.  Additional Tips 1. Do not add HTH (chlorine) granules to a truck tank. They tend not
  to totally dissolve. They may dissolve later during fish hauling causing mortality. 2. Tanks that leak water back out of insulated walls after
  disinfection are difficult to disinfect. These tanks should again be spot disinfected
  immediately before use. 3. Air drying kills most pathogens. Keep equipment dry whenever
  possible. Last, but probably most important is the fact that healthy, good quality
  fish can fight off infections through their immune response. Fish of poor quality have a
  reduced immune response and are more susceptible to disease organisms.  Miscellaneous Stuff BY: MTAN   Remember that fish hatchery construction project MTAN spoke about now
    underway at the Keweenaw Bay Indian Reservation? Mike Donofrio said he has found a
    reliable and fair priced supplier for PVC pipe, valves and pipe fittings. The company's
    name is "Industrial Thermoplastic Solutions", P.O. Box 5029, Evansville, Indiana
47716 (800-262-4300). MTAN is glad to report that there is NOTRUTH to the rumor
  that Mike is receiving a kick-back for passing along this information.  Pond Culture Of Muskellunge In
    Wisconsin, by Leon D. Johnson. The material was published by the Wisconsin
    Conservation Department; Technical Bulletin Number 17. Although some of the material may
    be outdated (published in 1958), the book does discuss several interesting topics:
    Production of natural food, pond preparation and management, spawning operations,
    incubation, stocking fry and forage species plus harvesting of ponds.
  Hatchery Tips By: MTAN Automatic Debris Cleaner: Are you tired of cleaning the debris out of
  the tail race of rearing tanks? If so, insert a section of sealed plywood (two inches off
  the bottom) between the tail screen and the damboards/stand pipe. This will force the
  outgoing water to be drawn off the bottom of the tank/raceway. Debris that collects at the
end of the tank is then drawn off with the outgoing water. Siphon Device For Cleaning Small Tanks: Getting rid of unused food or
  waste products in fish starter tanks is a time consuming process. If the water is drained
  off too quickly the fry will become impinged on the tail screen. By using a
  "Tee" type suction device you will save fry and many hours of labor. The device
  is made from 1/2" PVC plastic and clear plastic tubing. The head end of the Tee has a
  thin cut which allows debris to enter but still eliminates fry from being sent to the
  settling basin. The long end of the Tee works as a handle while the siphon hose is
diverted to the floor drain or a empty five gallon bucket. Fish Crowder For Tanks and Raceways: Sections of rubber innertube
  nailed over the ends of a fish crowding screen can reduce injury to fish when crowding
  raceways. There should be a two inch space between the end of the crowding screen and the
  rubber innertube. If you then wedge the screen from the top, it will stay in place. For
  small rearing tanks, just staple foam pipe insulation to the sides of your wooden
crowders. More Oxygen Means Healthier Fish: The MTAN was informed by Mike
  Donofrio (Keweenaw Bay Indian Community) of a new improved system for injecting oxygen
  into your rearing tanks. Follow the same procedure for setting up a "Packed
  Column", with the exception of using corrugated drain pipe in place of smooth
  walled PVC pipe. Apparently the additional edging inside the pipe forces more water to
  flow over the plastic media. Mike reports that an additional 2ppm of oxygen resulted from
  this change. If your interested in obtaining some of this drain pipe, Mike has an
additional 50 feet he will sell for $1.00 per foot. Fiberglass Rearing Tanks: Two new sources for rearing tanks have just
  recently been brought to the attention of MTAN. They are Hyperdyne Corporation, 1001
  Beltrami Ave., Bemidji, MN 56601, 218-751-9310 and Tub Craft, P.O. Box 689, Baraga, MI
49908, 906-353-6660. Please Help To Keep MTAN Readers Better Informed: With all the years
  of fish culture experience which our MTAN readers have accumulated, it would be a great
  learning tool to others if we could communicate that knowledge. For those individuals who
  are experienced in fish culture, these hatchery tips may just be a second (or third)
  version of something you may already be doing. But for those people just beginning their
  hatchery operations, these tips (plus additional ideas by you), may indeed prove to be
  useful time savers. If you would like to share those "Tricks of The Trade",
  please write MTAN a brief explanation and drawing of your idea. We even promise to speelll
  your name correctly.   **Return
