As someone who’s had to make that call – keep the trophy or let it swim – I can tell you proper release technique matters more than most anglers realize. A fish that swims off looking strong can still die hours later if you handled it wrong.
Here’s what I learned everything from guides who catch and release dozens of big fish every week.
Keep Them in the Water

Submerged as much as possible is the goal. Support the body horizontally – never hold large fish vertically by the jaw. That weight hanging from the jaw damages internal organs and the jaw structure itself.
Wet your hands before touching any fish. Dry hands strip away the protective slime coat that shields them from infection. That slime takes days to regenerate, leaving the fish vulnerable.
Getting the Hook Out

Long-nose pliers or a proper dehooking tool speeds up the process. If the hook is deep – swallowed or in the gills – cut the leader close to the mouth. The hook will rust out faster than the fish will heal from your extraction attempts.
Circle hooks reduce gut-hooking significantly. If you release most of your catch, switching to circles is worth the adjustment period. That’s what makes them standard on charter boats now.
Actually Reviving Tired Fish
Move the fish forward through the water – never backward. Pushing water backward over the gills doesn’t work; they’re designed for forward flow. Gentle forward motion pushes oxygenated water across gill membranes.
Wait until the fish kicks strongly before letting go. A premature release often ends badly – tired fish sink to the bottom and don’t recover. You want to feel that powerful tail thrust before you open your hands.
Watch it swim away. If the fish rolls or struggles, gently retrieve it and continue revival. Sometimes they need another minute or two.
Handle releases properly and that trophy might still be there next season – for you or someone else to catch and admire.
