Catch and release is one of the simplest and most effective things an angler can do to protect a fishery and fish stocks for the future. A fish you return swims off to spawn, grows to trophy size, and may even give you or a fellow angler a thrilling fight on another day. Done carelessly, though, a release can cause severe internal damage, making it more harmful than keeping the fish for the table would be. The goal is straightforward: land the fish quickly, handle it as little as possible, practice proper fish handling techniques, and return it strong enough to swim away on its own. This comprehensive guide walks through the essential gear, handling procedures, and small habits that make the difference between a fish that survives and one that doesn't.
Essential Gear for Fish Care (Checklist)
A successful, fish-friendly release starts long before you ever make a cast. The right terminal tackle and fish care kit remove the vast majority of risks associated with handling:
- Barbless or micro-barb hooks: These come out cleanly, easily, and quickly, significantly cutting down on handling time and tissue damage in the fish's mouth. Many modern fisheries now make them mandatory.
- A knotless, rubberised landing net: A rubberised mesh doesn't absorb fish odors, dries quickly, and protects the fish's delicate protective slime coat and fins far better than old knotted twine.
- A padded unhooking mat or cradle: Provides the fish with a soft, wet, and safe surface if it has to be laid down on the bank for unhooking, measuring, or weighing.
- Long forceps or a disgorger: Allow you to reach and grip the hook quickly and precisely without digging your fingers deep into the fish's mouth.
- Single hooks instead of trebles: Wherever possible (especially in lure fishing), swap out trebles for single hooks — fewer hook points mean fewer injuries.
Tie your rigs with strong, reliable knots so nothing fails mid-fight, leaving a fish trailing meters of line. Our detailed guide to fishing knots covers secure rigs that pair perfectly with barbless hooks.
Before Unhooking: Minimise the Fighting Time
A long, exhausting battle floods a fish's muscles with lactic acid, which can cause fatal exhaustion hours after the release. Always use balanced tackle — ensure your rod, line, and reel drag are perfectly matched to the size of the fish you expect. This allows you to land it quickly and firmly rather than playing it to total exhaustion. Avoid under-gunning your tackle just for the thrill of a long battle; a fish landed in good condition has the highest survival rate. Have your landing net, forceps, and a wet unhooking mat ready before you get a bite, not while a tired fish is thrashing at your feet in the shallows.
Fish Handling Techniques: The Golden Rules
Most post-release mortalities come down to improper handling on the bank. Follow these rules without exception every single time:
- Always wet your hands, the unhooking mat, and the net mesh thoroughly before touching the fish. Dry surfaces instantly strip away the protective slime coat, leaving the fish highly vulnerable to lethal fungal infections and disease.
- Keep the fish extremely low, directly over a soft padded surface, grass, or the water. Never lift it high over rocks or hard banks, where an accidental drop would mean fatal internal injuries.
- Support the fish horizontally with both hands — one cupping the belly, the other firmly holding the tail wrist. Never hang a fish vertically by the jaw, gills, or operculum.
- Keep your fingers well clear of the eyes and gills, which are the most fragile and crucial organs of the fish.
- Minimise air time. Treat every single second out of water as if you were holding your own breath underwater.
Unhooking Quickly and Cleanly
With a barbless hook lodged in the lip, a simple squeeze and twist of the forceps usually frees it in seconds. Grip the bend of the hook, back it out along the exact angle it went in, and keep the fish steady and calm on the mat. If the hook is a bit deeper but you can still clearly see it, work the forceps down calmly with care — never rip or tear at the tissue. If a fish is hooked deeply 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 immediately. A hook left behind often rusts out quickly or is shed naturally, which is far better than the fatal damage caused by digging for it.
The Perfect Quick Trophy Photo
Taking a photo with a beautiful catch is perfectly fine, but prepare the setup first. Have the camera turned on, settings ready, and a friend with a finger on the shutter before the fish ever leaves the water. Lift and hold the fish for just a few seconds low over the unhooking mat, net, 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 violently, the photo session is over — its survival matters far more than a shot for social media.
Proper Fish Revival and Releasing
Never just drop a tired fish back into the water and walk away. Wade into the water with it, hold it upright and horizontally below the surface, facing into any available current (or move it gently forward, never backwards), allowing oxygen-rich water to flow naturally over its gills. Give it plenty of time to recover — after a hard-fought battle, this can take a minute or more. Keep in mind that fish recover much faster in cold water; in warm summer water, which holds less oxygen, they tire easily and need longer, more patient revival. When you feel the fish grip the water, tense its body, and kick its tail firmly to pull away from your hands, let it go. That strong tail kick is its way of letting you know it's ready.
Log the Release, Not the Harvest
You don't need to harvest a fish to keep the memory alive. Measuring a fish, noting its length and weight, and logging it turns a release into a valuable permanent record — and provides useful data on how a particular water is fishing. With BeAngler catch logging, you can easily record every release with precise details on length, weight, bait, and weather conditions, pinning it to the correct spot from our water bodies directory. Share this modern angling ethic with others in teams & clubs. A community that practices proper catch and release protects the waters for everyone.
