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.
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 ...
It has been compiled and is continuously updated by the curator emeritus of the CAS fish collection, William N. Eschmeyer. The taxonomy maintained by the Catalog of Fishes is considered authoritative and it is used as a baseline reference for instance by the broader global fish database FishBase , [ 1 ] [ 2 ] which involves cross-references to ...
The ladyfish are a coastal-dwelling fish found throughout the tropical and subtropical regions, occasionally venturing into temperate waters. [3] Spawning takes place at sea, and the fish larvae migrate inland entering brackish waters. Their food is smaller fish and crustaceans . Typically throughout the species, the maximum size is 1 m (3.3 ft ...
Bigeye tuna can grow up to 2.5 m (98 in; 8.2 ft) in length. Maximum weight of individuals probably exceeds 180 kg (400 lb), with the all-tackle angling record standing at 178 kg (392 lb). They are large, deep-bodied, streamlined fish with large heads and eyes.
The rohu is a large, silver-colored fish of typical cyprinid shape, with a conspicuously arched head. Adults can reach a maximum weight of 45 kg (99 lb) and maximum length of 2 m (6.6 ft), [2] but average around 12 m (1.6 ft). [citation needed]
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]
Growth chart. The largest recorded weight for a gafftopsail catfish is 4.54 kg (10.0 lb) [7] and 69 cm (27 in) in length. [8] A more common weight and length of gafftopsails caught is 1–2 lb (450–910 g) and 12–16 in (30–41 cm). As gafftopsail catfish grow longer, they increase in weight, but the relationship is not linear.
