Recreational fishing, also called sport fishing, is fishing for pleasure or competition. It can be contrasted with commercial fishing, which is fishing for profit, or subsistence fishing, which is fishing for survival.
The most common form of recreational fishing is done with a rod, reel, line, hooks and any one of a wide range of baits. Other devices, commonly referred to as terminal tackle, are also used to affect or complement the presentation of the bait to the targeted fish. Some examples of terminal tackle include weights, floats, and swivels. Lures are frequently used in place of bait. Some hobbyists make handmade tackle themselves, including plastic lures and artificial flies. The practice of catching or attempting to catch fish with a hook is known as angling.
Oily fish have oil in their tissues and in the belly cavity around the gut. Their fillets contain up to 30 percent oil, although this figure varies both within and between species. Examples include small forage fish, such as sardines, herring and anchovies, and other larger pelagic fish, such as salmon, trout, ilish and mackerel.
Oily fish can be contrasted with whitefish, which contain oil only in the liver, and much less overall than oily fish. Examples of whitefish are cod, haddock and flatfish. Whitefish are usually demersal fish which live on or near the seafloor, whereas oily fish are pelagic, living in the water column away from the bottom.
Tunagate was a 1985 Canadian political scandal involving large quantities of possibly tainted tuna that were sold to the public under order of the Minister of Fisheries and Oceans, John Fraser.
The story broke on September 17 in the CBC program the fifth estate. Fisheries inspectors had found that StarKist tuna, made by a New Brunswick plant, had spoiled and declared that it was “unfit for human consumption.”
