The Arctic lamprey is a commercially important edible fish with fatty flesh. It is reared in aquaculture. [4] The ammocoetes are used as bait. Threats to the spawning habitat of this species include pollution and the regulation of water flow by damming. Nevertheless, the IUCN has assessed this species as being of "Least Concern". [1]

World capture fisheries and aquaculture production by species group [1] This is a list of aquatic animals that are harvested commercially in the greatest amounts, listed in order of tonnage per year (2012) by the Food and Agriculture Organization. Species listed here have an annual tonnage in excess of 160,000 tonnes.
Polar seas is a collective term for the Arctic Ocean (about 4-5 percent of Earth's oceans) and the southern part of the Southern Ocean (south of Antarctic Convergence, about 10 percent of Earth's oceans). In the coldest years, sea ice can cover around 13 percent of the Earth's total surface at its maximum, but out of phase in the two hemispheres.
The Pacific Ocean is the largest of the world's oceans, extending from the Arctic in the north to Antarctica in the south. Covering 169.2 million square kilometers, it is larger than all of the Earth's land area combined. [9] The Pacific contains 25,000 islands (over half the islands in the world), most of which are south of the equator.
Arctic char exhibits a mostly circumpolar distribution. There is no other species of freshwater fish found at a higher latitude. [31] [32] [34] [35] Arctic char is native to Arctic and subarctic coasts and lakes of high elevations. In general, it has been observed in the Canadian Arctic, Greenland, Iceland, Scandinavia, Siberia, and Alaska.
There are various bird species that have been spotted in the Arctic. Eight species of birds reside on the polar tundra year round while 150 breed in the Arctic. [16] The birds that do breed go to the Arctic between May and July. One of the known birds is the snowy owl, which has enough fat on it to be able to survive in the cold temperatures.
Alaska blackfish are small, with an average length of 108 mm (4.3 in), but have been known to reach 330 mm (13 in). [3]They have an easily distinguishable morphology (a branch of biology dealing with the study of the form and structure of organisms and their specific structural features), with relatively large, posterior dorsal fin and anal fins, large, lobed pectoral fins located just ...
