Abstract
Cited and archive data on fecundity of 31 flatfish species are generalized for the North Pacific. General characterization of the fecundity is presented and correlation between absolute individual fecundity of the females and their body length or age is analyzed and formalized in equation form. Spatial variability of fecundity is described for different species: pacific halibut and starry flounder have the highest absolute fecundity in the eastern Bering Sea and Okhotsk Sea, greenland halibut, yellowfin sole, alaska plaice, sakhalin flounder, longhead dab, and flathead sole - in the Okhotsk Sea, northern rock sole - in the waters at East and West Kamchatka. kamchatka flounder - in the Bering Sea, arrowtooth flounder - in the Pacific waters at North America. So, the Okhotsk Sea is the area where the absolute fecundity of majority wide-spread flatfish species can reach the maximal level. However, the maximal fecundity of longsnouted flounder is higher in the Japan Sea than in the Okhotsk Sea.

Summary
Обобщены литературные и архивные материалы о плодовитости 31 вида камбал, обитающих в северной части Тихого океана. Выполнено сравнение географической изменчивости плодовитости камбал разных видов. Cited and archive data on fecundity of 31 flatfish species are generalized for the North Pacific. Обитающих в морях северной части Тихого океана, в той или иной мере посвятили свои работы многие исследователи (Фадеев, 1957, 1970а, б; Перцева-Остроумова, 1960, 1961, 1962; Тихонов, 1968, 1977, 1982; Иванкова, 1973; Иванков, Иванкова, 1974; Дьяков, 1982; Полутов, 1991а, б; Nichol, Acuna, 2001; Смирнов и др., 2007; и др.). 1. Описание общей характеристики плодовитости видов камбалообразных рыб, обитающих в северной части Тихого океана. Помимо очевидного теоретического значения полученных результатов, они послужат более глубокому пониманию определенных механизмов формирования численности важных промысловых объектов, к которым относится ряд видов камбалообразных рыб
