Abstract This paper reports the lipid contents and fatty acid compositions of the Krill Euphausia pacifica (total body lengths, <13 mm) collected in the Pacific water near Funka Bay, Hokkaido, Japan. Lipid contents were 3.2-11.0% on dry weight base, and highest in the samples of April. Most abundant fatty acids were palmitic acid (16:O)(20.4-23.3%), icosapentaenoic acid (20:5n-3, IPA) (16.5-26.9%) and docosahexaenoic acid (22:6n-3, DHA) (11.2-21.1%). DHA was higher in the August samples than in the April samples, whereas IPA was higher in the April. The present E. pacifica samples were similar in the lipid contents and concentrations of major fatty acids to those with total body lengths more than 1 3 mm collected in the same area.
