Fish measurement
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.
Some weight-length relationships use the total length of the fish while others use the fork length. It is important to measure the same kind of length that the reference relationship uses. It is also important to have the weight and length in the same units as the reference relationship. Weight vs. Length for Red Drum (data from Jenkins 2004)
List of largest fish
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
They measure an average standard length of 61.4 mm (2.4 in) and an average total length of 80.1 mm ... Unlike other fish they recruit directly on the benthos. [7]
total length The length from the tip of the snout to the tip of the tail. transverse Crosswise. trilobate Having three lobes. tricuspid Having three cusps or points. truncate Terminating abruptly, as if cut off square. trunk The region of a fish between the head and tail, or the last gill slit and vent. tubercle A small, usually hard ...
A slot limit is a tool used by fisheries managers to regulate the size of fish that can legally be harvested from particular bodies of water. Usually set by state fish and game departments, the protected slot limit prohibits the harvest of fish where the lengths, measured from the snout to the end of the tail, fall within the protected interval.
