Why Catch and Release Matters on the British Shore

Stand on any harbour wall from Cornwall to Caithness and you are fishing in water that has been worked for centuries. The cod, bass, ray and mackerel that swim past your baited hook are part of a long story of coastal living, and many of those stocks are under real pressure. Catch and release is not a gesture of sentimentality; it is a practical tool for keeping fish in the sea so that the next generation of shore anglers has something to cast at.

Done well, a released fish swims away strongly and suffers very little. Done badly, it dies an hour later, out of sight, and nobody learns anything. The difference comes down to a handful of habits that take only minutes to learn and cost almost nothing to adopt.

Gear Choices That Give Fish a Fair Chance

Your tackle does most of the work before a fish ever shows itself. The single biggest improvement you can make is to crush the barbs on your hooks. A barbless hook penetrates cleanly, comes out quickly and does far less tearing around the mouth and jaw. You will lose the occasional fish on a slack line, but most anglers find they land just as many once they keep a tight line and stop relying on the barb to hold.

• Crush the barb with fine pliers before you start fishing, not mid-session when your hands are cold and wet.
• Match hook size to target — a smaller hook set properly beats a large one that lodges deep in the throat.
• Use circle or semi-circle patterns for bait fishing where they are allowed; they tend to hook fish in the corner of the mouth.
• Fish heavier than you need to. A short fight on balanced tackle is kinder than a long one on line that is too light.
• Land fish on a wet mat or in a soft, knotless net rather than dragging them up a rough stone wall or over dry shingle.

If you are spinning for bass or pollack, consider swapping trebles for a single inline hook on your lures. It snags less, unhooks faster and does markedly less damage to a fish that is only going back.

Handling: Wet Hands, Quick Hands

A fish's protective slime layer is its first defence against infection. Dry hands, dry grass, dry concrete and dry netting all strip that coating away. Wet your hands in the sea before you touch anything. If you must put a fish down, put it on a wet mat, a wet towel or in the water — never on hot harbour stone in July.

Support the fish properly. For a bass, flatfish or cod, cradle it with one hand under the belly and the other gently gripping the wrist of the tail, keeping it horizontal. Do not hold a heavy fish up by the jaw or the gill covers; those tissues are not built for it. Keep the fish out of the air for as long as you can hold your own breath, and no longer. If a photograph is going to take longer than that, rest the fish in the water first, then lift it again.

Unhooking is where most avoidable damage happens. Use forceps or long-nosed pliers and back the hook out the way it went in. If a hook is deep in the throat or gut, cut the line as close to the hook as you can and leave it. A hook left in place corrodes or passes through far more often than people expect; a fish mauled by a hook-out usually does not survive.

The Water Is the Best Place to Recover a Fish

Once unhooked, get the fish back in the sea before anything else. Hold it gently in the current, upright, with its head pointing into the flow. Do not pump it up and down or squeeze it. On a beach, walk it out into the shallows and let it find its own feet, so to speak. From a harbour wall or pier, use a drop net or a soft sling to lower it back rather than dropping it from height.

• Wait for the fish to hold itself upright and start working its gills properly.
• Let go when it kicks — if it needs a nudge, a gentle push into the current is usually enough.
• Give it time. A tired bass or ray may need two or three minutes of support, especially in warm, low-oxygen water in late summer.
• Avoid release in the worst heat. On very hot, still days, fish early or late and release fish quickly rather than holding them for photographs.

When Fishing for the Pot Is the Right Choice

Catch and release is a tool, not a religion. If you intend to eat a fish and it is of legal size and from a stock that can take it, keep it humanely — a sharp knock to the head, bled and chilled promptly. The awkward middle ground is the fish you half-intend to keep, handle for five minutes, then let go. Decide before you cast what you are going to do, and stick to it.

Know your local rules too. Bass, sea trout and salmon all have closed seasons, minimum sizes and in some cases a mandatory catch and release requirement. These vary around the UK coast and change from year to year, so check the current regulations for your area rather than relying on what worked a decade ago.

Small Habits That Add Up Along the Coast

Every harbour, beach and rock mark has regulars who have fished it for thirty years and can tell you how the fishing has changed. Catch and release is how shore anglers stay part of the solution rather than part of the problem. Barbless hooks, wet hands, a soft net, a fast photograph and a proper recovery cost you almost nothing and can mean the difference between a fish swimming off strongly and a fish floating away.

Take your litter home, including line and bait packaging, and leave the mark as you found it. Teach a young angler to wet their hands before they touch a fish and you have done more for the coast than any single good session ever will. The sea gives generously when it is treated well — and shore anglers, of all people, have the most reason to keep it that way.
