Overall length. 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 ...
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)
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.
Average fork length for an adult fish throughout the entire range is about 85 cm (33 in). [12] Some fish may reach a length of 100 cm (39 in) or more, but most commonly they are around 64 cm (25 in). The largest little tunny on record is 120 cm (47 in) and 17 kg (37 lb). [13]
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.

Southern Hemisphere sharks are smaller and the two sexes are similar in size, with males and females attaining fork lengths of 2.0 and 2.1 m (6.6 and 6.9 ft) respectively. [10] Most porbeagles weigh no more than 135 kg (298 lb), with the record being a 230 kg (510 lb) individual caught off Caithness , Scotland , in 1993.
The maximum size recorded is a fork length of 71 centimetres (28 in), although total lengths around 35 centimetres (14 in) are more normal. The maximum published weight is 4 kilograms (8.8 lb). [ 1 ]
This fish has a maximum published total length of 70 cm (28 in), although a fork length of 27.6 cm (10.9 in) in males and 20.4 cm (8.0 in) in females is more typical. [ 3 ] Distribution and habitat
