A fishery (plural: fisheries) is an organized effort by humans to catch fish or other aquatic species, an activity known as fishing. Generally, a fishery exists for the purpose of providing human food, although other aims are possible (such as sport or recreational fishing, or obtaining ornamental fish or fish products such as fish oil. Industrial fisheries are fisheries where the catch is not intended for direct human consumption.
Regardless of purpose, however, the term fishery generally refers to a fishing effort centered on either a particular ecoregion or a particular species or type of fish or aquatic animal, and usually fisheries are differentiated by both criteria. Examples would be the salmon fishery of Alaska, the cod fishery off the Lofoten islands or the tunaThunnus alalunga Thunnus albacares Thunnus atlanticus Thunnus maccoyii Thunnus obesus Thunnus orientalis Thunnus thynnus Thunnus tonggol Tuna are several species of ocean-dwelling fish in the family Scombridae, mostly in the genus Thunnus . Tuna are fast fishery of the Eastern PacificFor other meanings of pacific see pacific (disambiguation). The Pacific Ocean (from the Spanish Pacifico meaning peaceful is the world's largest body of water. It encompasses a third of the Earth's surface, having an area of 179. 7 million km² (69. 4 mill. Most fisheries are marineSea water is water from a sea or ocean. On average, sea water in the world's oceans has a salinity of ~3. This means that for every 1 liter (1000mL) of sea water there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it., rather than freshwater; most marine fisheries are based near the coastUnited States postal stamp. A coast is that part of an island or continent that borders an ocean, gulf, sea, or large lake. In geology and geography, the coast extends inland from the shoreline. The terms coast and coastal refer to the condition of being. This is not only because harvesting from relatively shallow waters is easier than in the open ocean, but also because fish are much more abundant near the coastal shelfUnited States postal stamp. A coast is that part of an island or continent that borders an ocean, gulf, sea, or large lake. In geology and geography, the coast extends inland from the shoreline. The terms coast and coastal refer to the condition of being, due to coastal upwellingUpwelling is an oceanographic phenomenon that occurs when strong, usually seasonal, winds push water away from the coast, bringing cold, nutrient-rich deep waters up to the surface. Deep water nutrients consist of nutritional salts such as nitrates and ph and the abundance of nutrients available there.
Fisheries have been important parts of human life and food production throughout history. Fisheries have become a part of human cultures and mythologies, providing a community identity and a subject for artists throughout the ages. Partially, this is because fisheries are irretrievably wrapped up in humanity’s perpetual fascination with the sea, and partially, because they have been a major source of food and income for many communities throughout the ages. One of the world’s longest lasting trade histories is the trade of dry cod from the Lofoten area to the southern parts of Europe, Italy, Spain and Portugal. The cod trading started during the viking period or before, has been going on for more than 1000 years and is still important.
