Abstract
The article presents the results of the study of the population dynamics, spatial distribution, diet variability, food digestibility, growth rates and the impact of predatory gastropods Nucella heyseana ( N. heyseana ) and Ceratostoma burnettii ( C. burnettii ) on marine bivalves in Peter the Great Bay, Russia. The relationship between the size of N. heyseana and its prey, as well as its impact on the growth of surviving mollusks, is clarified. N. heyseana has a pelagic stage which allows it to populate artificial substrates and positively affect the cultivated Japanese scallop Myzuhopecten yessoensis by preferentially preying on Mytilus trossulus. C. burnettii does not have a pelagic stage, but by destroying trophic competitors of M. yessoensis on the sea floor, it also has a beneficial effect.
Keywords: predatory marine gastropods N. heyseana and C. burnettii, population dynamics, impact on bivalves
