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.
