E. E. Ovsyannikov (Pacific Fisheries Research Center, Vladivostok 690950) Walleye pollock pelagic eggs were caught in 2001 in the northern Sea of Okhotsk during mass spawning. The largest average size was found for eggs caught off western Kamchatka and in Shelikhov Bay, walleye pollock eggs size in the northern Sea of Okhotsk was somewhat smaller, and the smallest eggs were encountered off eastern Sakhalin. Size variability of walleye pollock eggs in the northern Sea of Okhotsk was clinal in character, while in the western and eastern parts of the sea local variability was observed. The size composition of spawning females, temperature and salinity, as well as their effects on the eggs size variability are considered. (Biologiya Morya, Vladivostok, 2004, vol. 30, no. 6, pp. 479–482). Key words: northern Sea of Okhotsk, walleye pollock, eggs, size, variability.
