Freshwater fish are fish species that spend some or all of their lives in bodies of fresh water such as rivers, lakes, ponds and inland wetlands, where the salinity is less than 1.05%. These environments differ from marine habitats in many ways, especially the difference in levels of osmolarity .
Most oceanic species (78 per cent, or 44 per cent of all fish species), live near the shoreline. These coastal fish live on or above the relatively shallow continental shelf. Only 13 per cent of all fish species live in the open ocean, off the shelf. Of these, 1 per cent are epipelagic, 5 per cent are pelagic, and 7 per cent are deep water. [16]

The family currently includes 20 species across seven genera. [2] Several species are important food sources for humans, especially Brama brama in South Asia . The earlier form of the pomfret's name was "pamflet", a word which probably ultimately comes from Portuguese pampo , referring to various fish such as the blue butterfish ( Stromateus ...
The New Zealand longfin eel (Anguilla dieffenbachii) is a species of freshwater eel that is endemic to New Zealand. It is the largest freshwater eel in New Zealand and the only endemic species – the other eels found in New Zealand are the native shortfin eel (Anguilla australis), also found in Australia, and the naturally introduced Australian longfin eel (Anguilla reinhardtii).
Aggregate of freshwater fish found in the Arctic. Twenty-eight different species of fishes occur in Arctic lakes or rivers. A few of these species spend a portion of their life in the ocean, but so long as they return to breed in freshwater, they have been included here. Brian W. Coad, James D. Reist. (2017). Marine Fishes of Arctic Canada ...
Species of eelpouts have adapted in order to grow and thrive in the extreme low temperatures of their habitats. The metabolic responses of Antarctic and temperate eelpout species during exercise and subsequent recovery at 0 °C [18] is a point of emphasis when understanding this species. Contrary to the hypothesis of reduced glycolytic capacity ...
Parasitic infections from freshwater fish are a serious problem in some parts of the world, particularly Southeast Asia [citation needed]. Fish that spend part of their life cycle in brackish or fresh water, like salmon (an anadromous coastalfish closely related to trout), are a particular problem.
