Hyperoglyphe antarctica, the Antarctic butterfish, bluenose warehou, deepsea trevally, blue eye trevalla, blue-eye cod, bluenose sea bass, or deep sea trevalla, is a medusafish of the family Centrolophidae found in all the southern oceans, at depths of between 40 and 1,500 m. Its length is up to about 140 cm, with a maximum published weight of 60 kg.
Antarctic butterfish have a dark blue body above and lighter blue below with large eyes (another name for this fish is big eye). Larger individuals have a bronze sheen along the flanks.
They can grow to 1.4 m in length and over 50 kg in weight. Studies have shown that fish between 62 and 72 cm are mature and range in age between 8–12 years respectively. Mature females can produce between 2 million and 11 million eggs prior to spawning.
Blue eye mainly feed on the tunicate Pyrosoma atlantica. However, they will feed on a range of fish, molluscs, squid and crustaceans, and are also cannibalistic.
This species is present in five distinct areas: Argentina, South Africa, southern Australia, Saint-Paul & Amsterdam French Austral Islands and New Zealand. Spawning appears to occur in an area north east of Tasmania during March and April.
Little is known about the egg and larval stages of blue eye. Recently Antarctic butterfish of approximately 10 cm have been found living in association with large masses of floating kelp. It is believed that as these juveniles reach 50 cm they become semi-bottom dwelling.
These young fish form schools over hard bottom at depths of around 350–450 m, moving to deeper waters as they grow.
The ide, or orfe, is a freshwater fish of the family Cyprinidae found in larger rivers, ponds, and lakes across Northern Europe and Asia. It has been introduced outside its native range into Europe, North America, and New Zealand. It is a popular ornamental fish, usually kept in outdoor ponds in temperate regions from which it often escapes.
The Antarctic toothfish, also known as the Antarctic cod, is a large, black or brown fish found in very cold (subzero) waters of the Southern Ocean near Antarctica. It is the largest fish in the Southern Ocean, feeding on shrimp and smaller fish, and preyed on by whales, orcas, and seals. It is caught for food and marketed as Chilean sea bass together with its sister species, the more northerly Patagonian toothfish. Often mistakenly called "Antarctic cod", the Antarctic toothfish belongs to the notothen family (Nototheniidae), a family of fish genera that are abundant near Antarctica.

Dissostichus, the toothfish, is a genus of marine ray-finned fish belonging to the family Nototheniidae, the notothens or cod icefish. These fish are found in the Southern Hemisphere. Toothfish are marketed in the United States as Chilean sea bass or less frequently as white cod. "Chilean sea bass" is a marketing name coined in 1977 by Lee Lantz, a fish wholesaler who wanted a more attractive name for selling the Patagonian toothfish to Americans. In 1994, the U.S. Food and Drug Administration (FDA) accepted "Chilean sea bass" as an "alternative market name" for Patagonian toothfish. The toothfish was remarkably successful in the United States, Europe and Asia, and earned the nickname "white gold" within the market. Toothfish are vital to the ecological structure of Southern Ocean ecosystems. For this reason, on 4 September a national day is dedicated to the toothfish in South Georgia.
Paranotothenia magellanica, also known as Magellanic rockcod, Maori cod, blue notothenia or orange throat notothen, is a species of marine ray-finned fish, belonging to the family Nototheniidae, the notothens or cod icefishes.

Being a perciform fish, it is unrelated to the true cods of the order Gadiformes. This species is commercially important as a food fish.
