The rock cod (Lotella rhacina) is a temperate fish found off the coasts of southeastern Australia, Tasmania, the Great Australian Bight and northwards up the southwestern Australia coasts. They are also found around the coasts of New Zealand and California. They belong to the family Moridae and are not related to the true cods (genus Gadus). They are also known as beardie in Australia.

Rock cod are yellow-grey to red-brown with white fin margins. They have chin barbels. They may grow up to 50 cm in length. They are found in caves in bays and coastal reefs. They are frequently found inshore and inhabit shallow waters in the continental shelf with typical depth of 10 to 90 m.

Many other fish species are sometimes called 'rock cod', but most are unrelated to the cod family, and are better known as groupers.

Greenland cod

The Greenland cod, commonly known also as ogac, is a species of ray-finned fish in the cod family, Gadidae. Genetic analysis has shown that it may be the same species as the Pacific cod. It is a bottom-dwelling fish and is found on the continental shelf in the Arctic Ocean and northwestern Atlantic Ocean, its range extending from Alaska to West Greenland, then southwards along the Canadian coast to the Gulf of St. Lawrence and Cape Breton Island. It is a commercially harvested food fish, but landings have been greatly reduced in recent years.

Eastern freshwater cod

The eastern freshwater cod, also known as the eastern cod or Clarence River cod, is a large predatory freshwater fish of the genus Maccullochella and the family Percichthyidae, that occur in the coastal Clarence River system of north-eastern New South Wales. Eastern freshwater cod are closely related to the Murray cod of the Murray-Darling River system, and are considered an icon of the Clarence River system.

Cod fisheries

Cod fisheries are fisheries for cod. Cod is the common name for fish of the genus Gadus, belonging to the family Gadidae, and this article is confined to three species that belong to this genus: the Atlantic cod, the Pacific cod and the Greenland cod. Although there is a fourth species of the cod genus Gadus, Alaska pollock, it is commonly not called cod and therefore currently not covered here.

Coastal fish

Coastal fish, also called inshore fish or neritic fish, inhabit the sea between the shoreline and the edge of the continental shelf. Since the continental shelf is usually less than 200 metres deep, it follows that pelagic coastal fish are generally epipelagic fish, inhabiting the sunlit epipelagic zone. Coastal fish can be contrasted with oceanic fish or offshore fish, which inhabit the deep seas beyond the continental shelves.

Longfin grouper
