Catch and Release Best Practices: How to Release Fish That Survive

Catch and release only works if the fish survives. Studies show that improper handling can cause mortality rates of 30% or higher. Do it right, and over 95% of released fish survive.

Before the Catch

• Use barbless hooks or pinch down barbs — faster removal means less handling time
• Use appropriate tackle strength so you can land fish quickly. Exhausted fish have higher mortality
• Wet your hands before touching fish — dry hands remove their protective slime coat

Landing the Fish

Use a rubber-coated net instead of nylon — it’s gentler on scales and fins. Never use a towel or rag to grip fish. Lip grips work for some species but should support the body weight — don’t hang heavy fish vertically by the lip.

Hook Removal

Quality fishing pliers make hook removal fast and clean. Grip the hook shank and twist out following the curve. If the hook is deep, cut the line close to the hook — the fish’s body will dissolve or eject it naturally. A deep hook removal attempt causes more damage than leaving it.

Handling Rules

• Keep the fish in water as much as possible
• Support the body horizontally — never squeeze
• Minimize air exposure to under 30 seconds
• Never touch the gills
• Take photos quickly and have the camera ready before lifting the fish

Release Technique

Hold the fish upright in the water facing into the current. Support the belly and let the fish breathe. When it kicks strongly, let go. Don’t throw or drop fish back into the water.

Temperature Matters

Warm water holds less oxygen. Fish caught in water above 70°F (21°C) are already stressed. In summer, fish early morning or evening when water is cooler, and minimize fight time.
