Plankton The list of the phytoplankton of the Sea of Okhotsk contains 290 species of diatoms and 58 species of peridineans (P. Ushakov, 1953). According to the data of A. Zhuze and G. Semina (1955) diatomaceous sea-weeds are markedly predominant in the Sea of Okhotsk phytoplankton, comprising from 70 to 100 per cent of its biomass. This latter may reach.
