Paranotothenia magellanica, the Maori cod, is also known as Magellanic rockcod, blue notothenia or orange throat notothen. "Maori chief" and "black cod", sometimes used for this species, usually refer to fishes from the related genus Notothenia. It is a cod icefish in the family Nototheniidae commercially harvested from the Southern Ocean. It is found at depths down to 255 m, and its length is between 15 and 40 cm. It is a member of the order Perciformes and thus unrelated to the true cods.
The Maori cod takes its name from the Māori, the indigenous people of New Zealand. The range of the species spreads from the southern tip of South America, the Falkland Islands, southern New Zealand and associated islands, the Patagonian coast to sub-Antarctic regions, but it is rarely found in the Ross Sea. Because of its wide distribution, it is fished for by many countries, and is known by various names, such as orange throat notothen (South Africa), Maori cod (USA), Maori chief (USA), magellanic rockcod (USA), blue nonothenia (USA) and black cod (New Zealand).
The Maori cod is bluish on the back with irregular darker markings, and a greyish-yellow underside. The tail fin is square-cut, and the two lateral lines do not overlap. The first dorsal fin is small with only three or four spines.
It eats a variety of invertebrates and small fishes, together with seaweed. In turn, the Maori cod is an important diet item for seals and sea lions.
