Catch and Release Best Practices: How to Release Fish Safely

Why Catch and Release Matters

Catch and release is one of the most important conservation tools in recreational fishing. By releasing fish properly, anglers can enjoy the sport while maintaining healthy fish populations for future generations. Studies show that properly released fish have survival rates of 90-99% for most species. In many fisheries, catch and release regulations are what maintain trophy-quality fishing — without them, large breeding fish would be removed faster than they can be replaced.

Use the Right Gear

Proper gear selection starts the release process before you even catch a fish. Use circle hooks for bait fishing — they hook fish in the corner of the mouth 95% of the time, making release easy. Barbless hooks (or hooks with pinched barbs) reduce handling time and tissue damage. Use appropriate tackle strength so you can land fish quickly rather than fighting them to exhaustion. Rubber-coated nets cause less damage to fish than knotted mesh nets.

Handle Fish Properly

Fish have a protective slime coat that prevents infection — dry hands and rough surfaces remove this coating. Always wet your hands before handling fish. Support the fish horizontally — never hold a large fish vertically by the jaw, which can damage internal organs. Minimize air exposure to 15 seconds or less. If photographing, keep the fish over water and have the camera ready before lifting the fish. Lip grippers are acceptable for some species but should be used with support under the belly.

Revive Exhausted Fish

If a fish is too tired to swim away after a long fight, hold it gently in the water facing into the current (or move it forward and back in still water) until it kicks away under its own power. This forces water over the gills, re-oxygenating the blood. Don't release a fish until it can maintain its own balance. In warm water, a fish may need several minutes of revival. If fishing in warm water (above 75°F), use heavier tackle to land fish quickly and reduce stress.

When to Keep Fish

Catch and release is not always the right choice. Deeply hooked fish (hook in gills or stomach) have much lower survival rates — it's often more ethical to keep these fish if legal. Invasive species should generally be kept rather than released. Stocked trout in put-and-take fisheries are intended to be harvested. And sustainable harvest of plentiful species (bluegill, crappie, channel catfish) is perfectly appropriate. The key is following regulations and being mindful of the health of the specific fishery you're fishing.
