Gadopsis is a genus of temperate perches endemic to freshwater habitats in southeastern Australia. [2] The genus was formerly considered to be in a family of its own, Gadopsidae.
There are two species in this genus: [2]
Blackfish is a common name for the following species of fish and dolphins:
The Percidae are a family of ray-finned fish, part of the order Perciformes, which are found in fresh and brackish waters of the Northern Hemisphere. The majority are Nearctic, but there are also Palearctic species. The family contains more than 200 species in 11 genera. The perches, and their relatives are in this family; well-known species include the walleye, sauger, ruffe, and three species of perch. However, small fish known as darters are also a part of this family.
The members of the family Percichthyidae are known as the temperate perches. They belong to the order Perciformes, the perch-like fishes.
The tautog, also known as the blackfish, 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.
Sander is a genus of predatory ray-finned fish in the family Percidae, which also includes the perches, ruffes, and darters. They are also known as "pike-perch" because of their resemblance to fish in the unrelated Esocidae (pike) family. They are the only genus in the monotypic tribe Luciopercini, which is one of two tribes in the subfamily Luciopercinae,
The cunner, also known as the blue perch, bergall, chogset, choggie, conner or sea perch, is a species of wrasse native to the northwestern 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 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 species of freshwater fish in central California. A cyprinid, the blackfish is the sole member of its genus.
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 bathypelagic fish found in all tropical and temperate oceans at depths of 50 to 1,000 m. Its length is typically up to 60 cm (24 in), but it may reach 150 cm (60 in). Other common names include rudderfish and blackfish.
Gymnocephalus is a genus of ray-finned fishes from the family Percidae, which includes the perches, pike-perches and darters. They are from the Western Palearctic area, although one species, Gymnocephalus cernua has been accidentally introduced to the Great Lakes region where it is regarded as an invasive species. They have the common name "ruffe" and resemble the true perches in the genus Perca, but are usually smaller and have a different pattern.
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.
Schedophilus is a genus of fish in the family Centrolophidae, the medusafish. The genus has a global distribution.
Girella is a genus of sea chubs mostly native to the Pacific Ocean with a smaller presence in the Atlantic oceans.
Caesioperca is a genus of ray-finned fish in the sub-family Anthiinae in the sea bass family Serranidae. It contains just two species, found in the ocean off Southern Australia and New Zealand.
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, Eastern rock blackfish, black rockfish or Eastern rock blackfish drummer is a species of marine ray-finned fish, a sea chub from the family Kyphosidae. It is found in the southwestern Pacific Ocean around eastern Australian and northern New Zealand.
