Pacific krill

Pacific krill, Euphausia pacifica, is a euphausid that lives in the Pacific Ocean.

Pacific krill is fished intensively in the waters around Japan, where it is called isada krill or tsunonashi okiami (ツノナシオキアミ). The annual catch of krill in Japanese seas is limited to 70,000 metric tonnes by governmental regulations.

In the Pacific Ocean off the shores of the United States and Canada, E. pacifica is an important prey item of Cassin's Auklet and other planktivorous seabirds.
