摘要

Based on materials from trawling (2002-2005) and plankton (2(X)4-2006) surveys, some problems of the reproduction biology of the red king crab Paralithodes camtschaticus (Tilesius, 1815) population from Peter the Great Bay are considered. It was shown that the width of the carapace varied from 105 to 190 mm in female red king crabs with eggs; 50% of the females reached maturity with a carapace width of 112.8 mm. The average individual absolute fecundity of females was 200000 (114000-296000) eggs. A direct linear correlation between fecundity and female carapace width was recorded. The zoeas Ⅰ-Ⅳ of the red king crab occurred in the plankton from the middle of April up to the end of the second decade of May at water temperatures from 2.8 up to 9.3℃. The periods of larval occurrence in plankton in various years correlated with the water temperature, with a temperature decrease, the duration of the pelagic period increased. No direct correlation was revealed between the phytoplankton bloom and larval release. The density of red king crab larvae in Peter the Great Bay did not exceed 0.02-13.3 spec./m~3. The maximum concentration of zoeas was recorded in the central part of Ussuriysky Bay.
