Euphausia pacifica, the North Pacific krill, is a euphausid that lives in the northern Pacific Ocean.[2]
In Japan, E. pacifica is called isada krill or tsunonashi okiami (ツノナシオキアミ). It is found from Suruga Bay northwards, including all of the Sea of Japan and the south-western part of the Sea of Okhotsk. E. pacifica is fished from Cape Inubō north.[2] The annual catch of krill in Japanese seas is limited to 70,000 metric tonnes by government regulations. E. pacifica is also fished, albeit on a smaller scale, in the waters of British Columbia, Canada.[2]
E. pacifica is a major food item for various fish, including Pacific cod, Alaska pollock, chub mackerel, sand lance, North Pacific hake, Pacific herring, dogfish, sablefish, Pacific halibut, chinook salmon and coho salmon.[2]
