Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. [1] Total and fork length of a fish. Total length (TL) is the length of a fish measured ...
Standard weight equation for largemouth bass [1] and burbot [2] (fish). Standard weight in fish is the typical or expected weight at a given total length for a specific species of fish. Most standard weight equations are for freshwater fish species. Weight-length curves are developed by weighing and measuring samples of fish from the population.
A tuna (pl.: tunas or tuna) is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae family.The Thunnini comprise 15 species across five genera, [2] the sizes of which vary greatly, ranging from the bullet tuna (max length: 50 cm or 1.6 ft, weight: 1.8 kg or 4 lb) up to the Atlantic bluefin tuna (max length: 4.6 m or 15 ft, weight: 684 kg or 1,508 lb), which ...
Condition index in fish. The condition index in fish is a way to measure the overall health of a fish by comparing its weight with the typical weight of other fish of the same kind and of the same length. The condition index is its actual weight divided by its expected weight, times 100%. A fish of normal weight has a condition index of 100 ...
Biomass – the total weight of a fish species in a given area. Can be measured as the total weight in tons of a stock in a fishery, or can be measured per square metre or square kilometre. The most successful species worldwide, in terms of biomass, may be the Antarctic krill, with about five times the total biomass of humans.
Seafood. Seafood includes any form of food taken from the sea. Annual seafood consumption per capita (2017) [1] Seafood is the culinary name for food that comes from any form of sea life, prominently including fish and shellfish. Shellfish include various species of molluscs (e.g., bivalve molluscs such as clams, oysters, and mussels).
The king of herrings is the longest bony fish. Its total length can reach 11 m (36 ft), and it can weigh up to 272 kilograms (600 lb). It is a rarely seen oarfish, found in all the world's oceans at depths of between 20 m (66 ft) and 1,000 m (3,300 ft). [65] Mekong giant catfish
A negative certification may result in that nation's fishing vessels losing U.S. port access and potential import restrictions on fish or fish products. [28] In 2017, the Seafood Import Monitoring Program was established under NOAA Fisheries to increase transparency and traceability for 13 species of seafood particularly vulnerable to IUU ...
