Catch and release: best practices to keep fish alive | BeAngler

Catch and release is one of the simplest things an angler can do to protect a fishery for the future. A fish you return swims off to spawn, grows bigger, and may even give you a fight again on another day. Done carelessly, though, a release can do more harm than keeping the fish would. The goal is simple: get the fish in quickly, handle it as little as possible, and put it back strong enough to swim away on its own. This guide walks through the gear, the handling and the small habits that make the difference between a fish that survives and one that doesn't.

Gear that helps fish survive

Good release starts before you ever cast. The right kit removes most of the risk:

• Barbless or micro-barb hooks come out cleanly and quickly, cutting handling time and tissue damage. Many fisheries now require them.
• A knotless, rubberised landing net protects the protective slime coat and fins far better than old knotted mesh.
• An unhooking mat or cradle gives the fish a soft, wet surface if it has to be laid down.
• Long forceps or a disgorger let you reach the hook without digging fingers into the mouth.
• Single hooks instead of trebles wherever you can swap them — fewer points means fewer injuries.

Tie your terminal tackle with strong, reliable knots so nothing fails mid-fight; our guide to fishing knots covers secure rigs that pair well with barbless hooks.

Before the fish: minimise the fight

A long, exhausting fight floods a fish with lactic acid and can be fatal hours after release. Balanced tackle — a rod, line and drag matched to the fish you expect — lets you land it quickly and firmly rather than playing it to total exhaustion. Don't under-gun yourself for the thrill of a long battle; a fish landed in good condition is the one most likely to swim away. Have your net, forceps and wet mat ready before you hook up, not while a tired fish thrashes at your feet.

Handling: the golden rules

Most release deaths come down to handling. Keep these rules every single time:

1. Wet your hands and your mat or net before touching the fish — dry hands strip the slime layer that defends against infection.
2. Keep the fish low, over soft ground, grass or water, never over rocks or hard banks where a drop means injury.
3. Support it horizontally with two hands — one under the belly, one near the tail. Never hang a fish vertically by the jaw.
4. Keep your fingers well clear of the gills and eyes, the most fragile parts of the fish.
5. Minimise air time. Treat every second out of water as if you were holding your own breath underwater.

Unhooking quickly and cleanly

With a barbless hook in the lip, a twist of the forceps usually frees it in seconds. Grip the bend of the hook, back it out along the angle it went in, and keep the fish steady on the mat. If the hook is deep but you can still see it, work the forceps down calmly rather than tearing. If a fish is hooked deep in the throat or gills and you cannot reach the hook safely, cut the line as close to the hook as possible and release the fish — a hook left in often rusts out or is shed, and that is far better than the damage of digging for it.

The perfect quick photo

A photo is fine, but prepare everything first. Have the camera on, settings ready and a friend lined up before the fish leaves the water. Lift, hold the fish low over the net, mat or water surface so a slip ends in a soft landing, take a couple of frames, and put it straight back. A few seconds is plenty. If the fish starts to struggle, the photo is over — its survival matters more than the shot.

Reviving and releasing

Don't just drop a tired fish back and walk away. Hold it upright in the water, facing into any current, and let oxygen-rich water pass over its gills. Give it time — a minute or more for a hard-fought fish. In cold water fish recover faster; in warm summer water they tire more easily and need longer, gentler revival because warm water holds less oxygen. When the fish grips the water, kicks firmly and tries to pull away, let it go. That kick is its way of telling you it's ready.

Record the release, not the kill

You don't need to keep a fish to keep the memory. Measuring a fish, noting its length and weight, and logging it turns a release into a lasting record — and into useful data on how a water is fishing. With BeAngler catch logging you record a release with length, weight, bait and conditions instead of taking the fish home, and you can pin it to the right spot from the water bodies directory. Share that ethic with others in teams & clubs, where a community that releases well protects the same waters for everyone. Create your free BeAngler account and start logging releases today.
