Euphausia superba is known as a main feed stuff of cetacean in the Antarctic Ocean. It belongs to the crustacean family and has a light rose color and a body length of 40-50 mm. The geographic distribution of Euphausia superba is limited to more southern area than lat.50°S. where the sea water temperature is within-2 ?? 5°C. The peculiarity of nutritive components ofEuphausia should be determined because it seems to be closely related to the growth of cetacean. With this in mind, the authors determined the contents of vitamin B12and inorganic substance in E. superba comparing with those of other crustacea. Results obtained were as follows: 1) Qualitative estimation of metals inEuphusia was made by general group separation, paperchromatography and polarography, and detected Ca, Cu, Cr, Fe, K, Mg, Na, P and S in Euphausia. 2) Quantitative determination of seven kinds of metals, Fe, P, Cu, Ca, Mg, K and Na was made for five kinds of crustacea. There was no appreciable difference in the metal contents among them (Table 2). 3) Vitamin B12 in Euphausia wasdetermined by microbiological assay for 14 kinds of crustacea.The content of vitamin B12 in Euphausia is relatively higher than that of other crustacea (Table 4).
