What it is
Perch hunt. A worm over a pinch of chop, a waggler against a feature, a pole in a lock mouth, a small lure where it is allowed. You are fishing a place, not a carpet of groundbait.
Unhooking is part of the method: spines, a bony mouth, forceps. Keepnets are a poor idea. Rivers wait until 16 June. Live fish must not be moved between waters.
