Blackfish is a common name of fish.
The tautog or blackfish, Tautoga onitis, is a species of wrasse native to the western Atlantic Ocean from Nova Scotia to South Carolina. This species inhabits hard substrate habitats in inshore waters at depths from 1 to 75 m. It is currently the only known member of its genus.
The river blackfish is a freshwater fish endemic to the temperate waters of south-eastern Australia. It is found from southern Queensland through to central Victoria, including in the Murray-Darling river system. It is also found in some eastern and southern flowing coastal rivers. Found primarily in upland and "midland" habitats, though early records of fish fauna suggest it was originally far more extensively distributed and was found in some lowland habitats as well. Originally, river blackfish co-inhabited many of its lowland and "midland" habitats with species such as Murray cod and golden perch, and its upland habitats with species such as trout cod and Macquarie perch. It is a popular angling fish in some parts of its range.
The two-spined blackfish is a species of temperate perch endemic to Australia.
The bergall, also known as the cunner, conner or chogset, Tautogolabrus adspersus, is a species of wrasse native to the western Atlantic, where it is found from the Gulf of St. Lawrence and Newfoundland to the Chesapeake Bay. They inhabit inshore waters living near the sea floor at depths from 10 to 128 m, preferring areas with beds of seaweed, shipwrecks, or wharf pilings. They spend the winter months in a state of torpor underneath rocks. They can also be found in the aquarium trade.
Australia has over 5000 described species of fish, a quarter of which are endemic. Seafood and aquaculture are major and highly regulated industries, and fishing for marine and freshwater native and stoked fish is popular.
The Alaska blackfish is a species of freshwater fish in the esocid family (Esocidae) of order Esociformes. It inhabits Arctic regions of Alaska as well as Siberia and the Bering Sea islands.
The Sacramento blackfish is a cyprinid fish of central California. It is the sole member of its genus.
The parore or luderick, black bream or blackfish is a species of sea chub native to coastal marine and brackish waters of southeastern Australia and New Zealand. They prefer rocky reefs, inshore habitats such as eelgrass beds, estuaries and mangrove swamps where they can be found down to depths of around 20 metres (66 ft). This species can reach a length of 71 centimetres (28 in) FL though most do not exceed 35 centimetres (14 in) TL. The maximum known weight of this species is recorded at 4 kilograms (8.8 lb). They have 11-12 fine dark tapering bars on a bluish-grey to greyish-brown body that fades to silvery-white below. It is commercially important and is also popular as a game fish.
The Girellinae are a subfamily of fish in the sea chub family. They may be referred to as nibblers.
The black ruff is a medusafish, the only member of the genus Centrolophus. It is a mesopelagic fish found in all tropical and temperate oceans at depths of 50 to 1,000 m. Its length is typically up to 60 cm, but it may reach 150 cm. Other common names include rudderfish and blackfish.
The pelagic butterfish, Schedophilus maculatus, is a medusafish of the genus Schedophilus found in all warm oceans. Its length is up to about 30 cm.
The imperial blackfish, Schedophilus ovalis, is a medusafish of the family Centrolophidae found in the eastern Atlantic and the Mediterranean Sea, and occasionally off the coast of South Africa at depths of between 70 and 700 m. In its juvenile stage it is often found finding shelter amongst of the tentacles of the Portuguese man o' war. Its length is up to 100 cm.
The New Zealand ruffe, Schedophilus huttoni, is a medusafish of the family Centrolophidae found in all southern oceans south of latitude 18°S, at depths of up to 1,000 m. Its length is up to 90 cm.
Gadopsis is a genus of temperate perches endemic to freshwater habitats in southeastern Australia. The genus was formerly considered to be in a family of its own, Gadopsidae.
The Umbridae (mudminnows) are a family of Actinopterygii, ray-finned fish that inhabit freshwater environments in temperate regions across the Northern Hemisphere. They are generally small fish, with the largest species reaching 33 cm (13 in) in length, and most less than half that.
Girella is a genus of sea chubs mostly native to the Pacific Ocean with a smaller presence in the Indian and Atlantic oceans.
Dallia is a genus of mudminnows native to Russia and Alaska. Molecular data indicates the genus is more closely related to Esox and Novumbra than Umbra.Dallia diverged from Novumbra + Esox approximately 66 million years ago.
Girella elevata, the rock blackfish or black drummer is a species of sea chub native to coastal waters, around 25 metres (82 ft) depth, from Australia to New Zealand. This species can reach a length of 62 centimetres (24 in) SL. It is a highly sought after target of recreational fishermen due to its reputation as a brutally tough fighter when hooked and fine eating qualities. Because its preferred habitat is in the white-wash around rocky outcrops immediately along the coastal shoreline, most anglers targeting rock blackfish are land-based. Rock blackfish can also be caught from water craft, but this is considered a high-risk activity due to the dangers of fishing very close to shore.
