Perch Angling Welfare: Best Practice for a Beloved Sport Fish

Perch are one of the most popular freshwater angling targets in Europe. Understanding welfare-conscious angling practices helps anglers minimise harm to these fish.

Key Facts

European perch are widespread freshwater predators found across Europe and western Asia
They are caught by lure, worm, and small fish baits by anglers across their range
Perch have sharp dorsal spines that can cause injury to anglers and that complicate safe unhooking
Deep-hooking of perch, particularly on worm baits, is a significant welfare problem causing internal injury
Perch populations have declined in many lakes due to eutrophication and invasive species competition

Welfare Considerations

Perch welfare in angling is primarily affected by deep-hooking when fish swallow baits intended to be struck early. Internal hook injury causes bleeding, organ damage, and infection. Handling perch incorrectly — gripping the sharp dorsal spines without protection — injures both fish and angler. Air exposure during unhooking and photography causes physiological stress. Best practice includes using smaller hooks with early strike timing, minimising air exposure, and releasing fish directly into water rather than onto hard surfaces.

What You Can Do

Strike early when perch angling to prevent deep-hooking and internal injury
Use protective gloves when handling perch to protect their dorsal spines and your hands
Minimise photography and handle fish over the water to reduce air exposure
Report evidence of stressed or unhealthy perch populations to local fisheries managers
