Weight vs. Length for Red Drum (data from Jenkins 2004) The reference weight-length formula is used to calculate how much the individual fish would be expected to weigh based on its measured length. Then the condition index is the actual weight of the fish divided by its expected weight, times 100%.
The crevalle jack is one of the largest members of Caranx, growing to a known maximum length of 125 cm and a weight of 32 kg, [6] although it is generally uncommon at lengths greater than 65 cm. [10] Unverified reports of fish over 150 cm may also be attributable to this species. [11]
The trawl rationalization catch share program is a program that is based on catch limits which are constructed from the health of each fish stock. This is then divided into shares and given to individual fishermen and groups. Such management is under the Pacific Coast Groundfish Fishery Management Plan. [16]
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
The species is listed as Endangered under the Fisheries Management Act 1994 (New South Wales) and as Threatened under the Flora and Fauna Guarantee Act 1988 (Victoria). Recreational fishing targeting southern bluefin tuna is permitted in all states and territories and is regulated by various combinations of bag, boat and possession limits.
The coho salmon (Oncorhynchus kisutch; Karuk: achvuun [1]) is a species of anadromous fish in the salmon family and one of the five Pacific salmon species. Coho salmon are also known as silver salmon (or "silvers") and is often sold as medium red salmon. [2] The scientific species name is based on the Russian common name kizhuch (кижуч).
These coastal reefs are also visited by pelagic species of red sea fish, including some of the 44 species of shark. Approximately 40% of the Red Sea is quite shallow (under 100 m/330 ft), and about 25% is under 50 m (164 ft) deep. About 15% of the Red Sea is over 1,000 m (3,300 ft) depth that forms the deep axial trough.
The gharial (Gavialis gangeticus), also known as gavial or fish-eating crocodile, is a crocodilian in the family Gavialidae and among the longest of all living crocodilians. Mature females are 2.6 to 4.5 m (8 ft 6 in to 14 ft 9 in) long, and males 3 to 6 m (9 ft 10 in to 19 ft 8 in).
