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 coarsefish are freshwater fish that are not salmonids.
Fly fishing is an angling method in which an artificial "fly" is used to catch fish. The fly is cast using a fly rod, reel, and specialized weighted line. Casting a nearly weightless fly or "lure" requires casting techniques significantly different from other forms of casting.
Deep sea fishing is a form of angling that requires deep waters and usually takes place further away from land. The water depth should be at least 30 meters to be considered deep sea fishing territory. This fishing method is also often called offshore boat fishing, sport fishing, and big game fishing.
