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 ...
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.
The largest fish of the now-extinct class Placodermi was the giant predatory Dunkleosteus. The largest and most well known species was D. terrelli, which grew almost 9 m (29.5 ft) in length [21] and 4 t (4.4 short tons) [22] in weight. Its filter feeding relative, Titanichthys, may have rivaled it in size. [23]
A fish (pl.: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits.Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians.
When the body length is 4 to 8 cm (1.6 to 3.1 in), they start feeding on small fish. A pike has a very typical hunting behaviour; it is able to remain stationary in the water by moving the last fin rays of the dorsal fins and the pectoral fins .
standard length (SL) The length of a fish measured from the tip of the snout to the posterior extremity of the hypurals, the expanded bones at the end of the backbone that support the caudal fin. submarginal Almost at the edge. suborbital Below the eye. superior Above or on the upper surface. supracleithrum
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 ...
Siganus rivulatus has a laterally compressed body which has a standard length of 2.7-3.4 times the greatest body depth. [9] The dorsal fin has 14 spines and 10 soft rays, the anal fin has 7 spines and 9 soft rays, there are 23 vertebrae [10] and the caudal fin is slightly forked. [11]
