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 Magazine, Advertising Department, P.O. Box 2329, Asheville, NC 28802 (704-254-7334).

Steps For Equipment 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.

The mailing list for the MTAN newsletter has now grown to 43. Of that number there are currently twelve Tribal fish hatchery programs who receive (and hopefully read) the newsletter. These Reservations in serving Tribal subsistence and commercial needs, are also contributing significant fish stocks to Reservation waters fished by over 95% non-Indian anglers. During 1992, over 82 million fish were released into both on and off-reservation waters. A listing of these Reservations and the fish species stocked, was submitted by Bob Jackson (Bureau of Indian Affairs), and has been attached to this MTAN edition. MTAN wishes to congratulate all those people involved for these very successful hatchery programs.

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.

MTAN came across an interesting publication which may be of interest to you muskellunge enthusiasts. The book is called 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.
