Coldwater fish

Source: Wikipedia, the free encyclopedia.
Japanese koi carp are coldwater fish.

The term coldwater fish can have different meanings in different contexts.

Fishkeeping

Most or all

stenothermic tropical species having critical thermal minimums of around 10-12 °C.[1] Although these fish are capable of surviving in unheated aquaria, their temperature preferences may vary. For example, koi, goldfish, and pond loaches are commonly considered to be cold-water fish because of their ability to survive at very low temperatures, but their temperature preferences and/or physiological optimal temperatures are 32 °C (90 °F),[2] 24-31 °C (75-88 °F),[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] and 26-28 °C (79-82 °F),[22]
respectively. Because many of the ornamental fish considered to be “coldwater fish” are more accurately eurythermal fish and many prefer temperatures similar to, or even warmer than those preferred by certain tropical fish, the term “coldwater fish” in the aquarium context often misleads pet owners into keeping fish below their preferred temperature.

Freshwater aquarium fish

Note: The above contains a mix of true coldwater fish and sub-tropical fish that can survive and thrive at room temperature which ranges from 15 °C (59 °F) and to 30 °C (86 °F).[23]

Freshwater pond fish

Saltwater aquarium fish

Wild fisheries

The term "coldwater" is also used to refer to wild fish species that prefer

gadiforms (cods, hakes, pollock, haddock, burbot and rocklings, etc.), however become stressed at warm temperatures and are most active in colder temperatures around 7–18 °C (45–65 °F) which resemble a more subarctic or alpine condition. Because these designations are informal, different fisheries management
authorities may recognize different boundaries in temperature preference between the categories.
