Coarse fishing is a term used in the United Kingdom and Ireland for angling for coarse fish. Coarse fish are freshwater fish that are distinguished from game fish. Freshwater game fish are all salmonids – most particularly salmon, trout and char – so generally coarse fish are freshwater fish that are not salmonids. There is disagreement over whether grayling should be classified as a game fish or a coarse fish.Fly fishing is the technique usually used for freshwater game fishing, while other angling techniques are usually used for coarse fishing. The sport of coarse fishing and the techniques it uses are particularly popular in the United Kingdom and mainland Europe, and as well as in some former British Commonwealth countries and among British expatriates.
The distinction between coarse fish and game fish has no taxonomic basis. It originated in the United Kingdom in the early 19th century. Prior to that time, recreational fishing was a sport of the gentry, who angled for salmon and trout and called them game fish. There was a view that other fish did not make as good eating, and they were disdained as coarse fish. Coarse fish have scales that are generally larger than the scales of game fish, and they tend to inhabit warmer and stiller waters.
A large array of baits can be used for a variety of fish. Baits used will vary accordingly to many factors. Some of these deciding factors include the venue being fished, the species of fish being targeted, time of year, and water colour. Also, the options of either moving or still water plays a part in the size, colour or style of bait being used.
When fishing on rivers for game fish, i.e. Brown, Rainbow, Brook and Sea Trout, Salmon and in some cases Grayling (game status debated), artificial flies, small spinners and lures are a popular choice for many game anglers due to the way they intentionally mimic a fly or small fish on the surface and top layers of the water, enticing the fish into feeding as it sits among actual live flies and fish fry. 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 summer months, a spinner or fly manoeuvred 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) 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 balls made with fish meal, milk, and soya) and luncheon meat (pork roll and tinned chopped pork).
