and released carefully will live to breed and be caught again. Catch-and-release can make a huge difference to the quality of fishing on our waters. This is the latest advice from the Wild Trout Trust.

How to release trout:

•Use tackle that is an appropriate strength for the size of fish you expect to catch, as this avoids you having to play fish for a long time before landing. Long fights in warm weather are especially damaging.

•Use barbless hooks and have forceps to hand in case of difficulty. If the fish is deeply hooked, cut the line as the hook will work its way out and this is less damaging than a prolonged wrestling match.

•Always use wet hands to handle fish, and handle as little as possible. Avoid squeezing it as this can damage internal organs.

•Keep the fish in the water and avoid landing on the bank or on gravel as this removes the surface slime and leaves the trout vulnerable to fungal infections.

•Photograph your fish close to the water, holding it out of the water as briefly as possible.

•Release the fish by pointing its nose into the current so that water is flowing over its gills.
