Handling and Releasing Fish
Tips for Handling and Releasing Fish
Fish
that you don't intend to keep or fish that are smaller than the legal
length should be released immediately and gently.- Avoid handling fish excessively. The mucous covering the fish's body should be protected because it prevents infection.
- Hold fish firmly. A fish dropped on the ground or in a boat has a poor chance for recovery.
- Grasp large-mouthed fishes by the lower jaw with thumb and forefinger; smaller fishes with your hand around the mid-section, wetting hands first. Fish with teeth may be handled by grasping them across the gill covers.
- Never put your fingers in the gills or eye sockets.
- Every angler should carry a hook disgorger or needlenose pliers. Back the hooks out if possible.
- Never pull a hook from the fish's throat or stomach. It is better to cut the line. Many hooks will rust away.
- Use hooks with barbs squeezed shut if you intend to release all fish or if you like additional challenge.
How to measure fish length
Total length is measured from the tip of the snout to the end of the tail with the fish laid flat, mouth closed, and tail lobes pressed together.
From the time a fish is caught, until it is released after the weigh-in, there are 3 phases of handling which affect its chances for survival.
1. Hook removal --
Avoid handling fish excessively. Hold the fish firmly by the lower jaw and gently remove the hook. Every angler should carry a hook disgorger or needlenose pliers. Never pull a hook from the fish's throat or stomach; it is better to cut the line and let the hook work itself out. Fish that are smaller than the legal length limit must be released immediately.
2. Live well --

The proper use of a live well is critical in any successful release program. Don't allow water to drain from the live well when moving the boat. Live wells should be aerated and have smooth inside walls. It is best to keep the water in the live well fresh, and as close to the actual lake temperature as possible. Live well capacity is important. A small live well stuffed with a limit of fish is as useless as no live well at all. You should put no more than 3/4 pounds of fish per gallon of water in a well aerated live well. Most live wells can hold about 11 gallons of water plus 8 pounds of fish. For bass, this means four, 2 pound fish (15.5" each).
A solution to overcrowded live wells during fishing tournaments is to measure and release all but trophy size fish immediately. Length-weight tables can then be used to assign standard weights to all sizes of fish.
3. Weigh-in --
Assuming the fish has been treated properly in the live well, the weigh-in is the final and often the most critical phase affecting its survival. Fish which are held out of the water during the weigh-in or during photographic sessions have little chance of surviving after release. Fish should be kept in the live well until participants leave their boats. As fisherman leave their boats, fish can be put into round plastic laundry baskets. A series of 50 gallon plastic garbage cans may be spaced every 10 feet up to the scales so that baskets of fish can be kept in the water right up until the actual weigh-in. The water in these cans must be kept fresh or aerated. The use of plastic water bags to carry fish to the scales is discouraged.
Although this principal works well for transporting aquarium fish home from the pet shop, it does not work well at a fish tournament. To use these unaerated bags effectively, they should contain about one gallon of fresh water for each 1/4 pound of fish, or 8 gallons of water (weighing about 65 pounds) for each 15 inch bass in the bag.
Fish clubs should assign people to coordinate fish release. After the weigh-in fish should be classified as releasable or non-releasable. Non-releasable are dead, weak or injured fish. It is better to keep any questionable fish as food than to waste them by returning them to the lake. A successful, well carried out release program is a credit to any fishing club.
Finally, three to five days after the release, club members should check the release area to remove any dead fish if necessary. The tournament should not be considered over until this has been done.
