Coarse fishing (Irish: garbhiascaireacht, Welsh: pysgota bras) is a phrase commonly used in Great Britain and Ireland.
When fishing on rivers for game fish (i.e., brown, rainbow, brook and sea trout, salmon and in some cases grayling), artificial flies, small spinners and lures are a popular choice for many game anglers due their ability to mimic prey items, (such as small invertebrates), on the surface and top layers of the water, enticing the fish into feeding.
[8] Both floating and sinking flies and lures can be used to fish either on the surface or in the upper layers of the water.
Usually, in the summer months, a spinner or fly manoeuvre across the surface will bring about a take from a fish due to the tendency of fish to move into the warmest part of the water, the surface and first layer—about 18 inches (46 cm)—of water below.
When fishing a river for coarse fish species, such as chub, barbel, roach, dace and bream, the favourite hook baits tend to be maggot (white, red, and bronze), caster (maggot chrysalis), worm, cheese, pellets (halibut, trout, and carp), boilies (round boiled baits typically made with fish meal, milk, and soya) and luncheon meat.
For all anglers in England and Wales, anyone aged 17 and over must purchase a valid rod licence before fishing.
Some lakes and river stretches are operated by angling clubs which charge annual membership fees.
Application forms can be available from local tackle shops or angling club websites.
Lately, advancements in technology and market competitiveness have led to many types of other ingredients being introduced, including chemicals, such as betaine, that stimulate the feeding response in fish.
