Notothenia rossii

The marbled rockcod (Notothenia rossii) is a species of notothen native to the Southern Ocean, where it can be found at depths from 5 to 350 m (16 to 1,148 ft). This species can reach a length of 92 cm (36 in), though most are only around 50 cm (20 in). The greatest recorded weight for this species is 10 kg (22 lb). This is a commercially important species. During the 1960s and 1970s, it was heavily fished by Soviet fishers, with catches exceeding 100,000 tonnes in some seasons; it almost disappeared from around South Georgia Island, and by 1980, was depleted throughout the Southern Ocean.
