It is approximately 32 kD (two 17 kD dimeric molecules). The protein was isolated from the blood plasma of winter flounder. It is considerably better at depressing freezing temperature than most fish AFPs. [10] The ability is partially derived from its many repeats of the Type I ice-binding site.
Cryoprotectant. A cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e. that due to ice formation). Arctic and Antarctic insects, fish and amphibians create cryoprotectants (antifreeze compounds and antifreeze proteins) in their bodies to minimize freezing damage during cold winter periods.
Like most other Antarctic notothenioids, the blackfin icefish produces antifreeze glycoproteins in their blood and other body fluids. [15] These proteins reduce the internal freezing temperature, preventing ice crystallization and thus allowing the fish to survive in water below 0 °C.
Ocean pout, Newfoundland, Canada. The ocean pout ( Zoarces americanus) is an eelpout in the family Zoarcidae. It is found in the Northwest Atlantic Ocean, off the coast of New England and eastern Canada. The fish has antifreeze proteins in its blood, giving it the ability to survive in near-freezing waters.
The spleen may be used to remove ice crystals from circulating blood. [ 9 ] [ 10 ] As the chilly Antarctic and sub-Antarctic waters of the Southern Ocean average −1 to 4 °C (30–39 °F), [ 11 ] most species of these regions produce antifreeze glycoproteins to prevent the formation of ice crystals in blood and other body fluids.
Burbot. The burbot (Lota lota), also known as bubbot, [2] mariah, [3] loche, cusk, [4] freshwater cod, [5] freshwater ling, freshwater cusk, the lawyer, coney-fish, lingcod, [6] or eelpout, is a species of coldwater ray-finned fish native to the subarctic regions of the Northern hemisphere. It is the only member of the genus Lota, and is the ...

Boreogadus saida, known as the polar cod[1][2][3] or as the Arctic cod, [1][4][5] is a fish of the cod family Gadidae, related to the true cod (genus Gadus). Another fish species for which both the common names Arctic cod and polar cod are used is Arctogadus glacialis. B. saida has a slender body, a deeply forked tail, a projecting mouth, and a ...
