Fishing is broadly split into three main disciplines; game, coarse and sea fishing.
Game fishing is fishing for ‘game' fish species which includes salmon, brown trout, sea trout and rainbow trout. Anglers go fishing for these species in streams, rivers and lakes/reservoirs i.e. in freshwater. These fish may be kept for eating (according to the fishing seasons and fishery rules).
Coarse fishing is fishing for any freshwater fish, other than salmon or trout. Coarse fish species include roach, perch, tench, carp, bream, rudd, pike and chub, for example. These fish are not kept for eating and are all returned.
Sea fishing is fishing that takes place in or by the sea, where you are trying to catch sea fish, such as bass, pollack, mackerel, plaice, cod and haddock, for example. This term includes fishing in estuaries.
