Fish Market
A fish market is a marketplace for selling Fish as food, fish and fish products.

Retail fish markets, a type of wet market, often sell street food as well. Fish markets range in size from small fish stalls to large ones such as the great Tsukiji fish market in Tokyo, which turns over about 660,000 tonnes a year.Clover C (2008''The End of the Line: How Overfishing Is Changing the World and What We Eat''Page 165.

Swim Bladder
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ (anatomy), organ in bony fish that functions to modulate buoyancy, and thus allowing the fish to stay at desired water depth without having to maintain lift (force), lift via swimming, which expends more energy. Also, the Dorsum (biology), dorsal position of the swim bladder means that the expansion of the bladder moves the center of mass downwards, allowing it to act as a stabilizing apparatus. Additionally, the swim bladder functions as a resonating chamber (anatomy), resonating chamber to produce or receive sound. The swim bladder is evolutionarily homology (biology), homologous to the lungs of tetrapods and lungfish, and some ray-finned fish such as bowfins have also evolved similar respiratory functions in their swim bladders. Charles Darwin remarked upon this in ''On the Origin of Species'', and reasoned that the lung in air-breathing vertebrates had derived from a more primitive swim b ...

Alaska Pollock
The Alaska pollock or walleye pollock (''Gadus chalcogrammus'') is a marine fish species of the cod genus ''Gadus'' and family Gadidae. It is a semi-pelagic Shoaling and schooling, schooling fish widely distributed in the North Pacific Ocean, North Pacific, with largest concentrations found in the eastern Bering Sea. Name and differentiation Alaska pollock was in 1956 put in its own genus, ''Theragra'', and classified as ''Theragra chalcogramma'', but research in 2008 has shown it is rather closely related to the Atlantic cod and should therefore be moved back to ''Gadus'', where it was originally placed. In 2014, the U.S. Food and Drug Administration announced that the official scientific name for the fish was changed from ''Theragra chalcogramma'' back to its original taxon ''Gadus chalcogrammus'', highlighting its close genetic relationship to the other species of the cod genus ''Gadus''. Since 2014, registries of scientific names for fish species (e.g. the United Nations' ASF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seine Fishing
Seine fishing (or seine-haul fishing; ) is a method of fishing that employs a surrounding net, called a seine, that hangs vertically in the water with its bottom edge held down by weights and its top edge buoyed by floats. Seine nets can be deployed from the shore as a beach seine, or from a boat. Boats deploying seine nets are known as Fishing vessel#Seiners, seiners. Two main types of seine net are deployed from seiners: ''purse seines'' and ''Danish seines''. A seine differs from a Gillnetting, gillnet, in that a seine encloses fish, where a gillnet directly snares fish. Etymology The word ''seine'' has its origins in the Old English ''segne'', which entered the language via Latin ''sagena'', from the original Greek σαγήνη ''sagēnē'' (a drag-net). History Seines have been used widely in the past, including by Stone Age societies. For example, the Māori people, Māori used large canoes to deploy seine nets which could be over a kilometer long. The nets were woven fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Game Fish

Some game fish are also targeted commercial fishing, commercially, particularly less bony species such as salmon and tuna. Specimens of game fish whose fish measurement, measurements (body length and standard weight in fish, weight) significantly exceed the species' average are sometimes known as trophy fish, as such captures are often presented as bragging rights among fishers. Examples The species of fish prized by anglers varies with geography and tradition. Some fish are sought for their value as seafood, food, while others are pursued for their fighting abilities, or for the difficulty of successfully enticing the fish to bite th ...
