Structure of Rapana venosa (Gastropoda, Muricidae) population of Sevastopol bays (the Black Sea)
Predatory invasive gastropod species Rapana venosa has become an important element of the Black Sea benthic ecosystem. Systematic monitoring of its populations is an important part of benthic ecosystem monitoring in the Black Sea. In this study the population of R. venosa has been investigated at f...

Predatory invasive gastropod species Rapana venosa has become an important element of the Black Sea benthic ecosystem. Systematic monitoring of its populations is an important part of benthic ecosystem monitoring in the Black Sea. In this study the population of R. venosa has been investigated at four bays in Sevastopol (Golubaya, Kazach’ya, Kruglaya and Streletskaya) during summer 2015. The main characteristics of R. venosa local populations were determined and compared. Size, weight, sex and age structure of Rapana local populations were studied and compared between these four sites. Current status and possible development of Rapana populations in four bays based on this analysis were accessed. It was found out, that Rapana population in the Kruglaya Bay is in the most stable condition with the most balanced structural parameters. Local populations of R. venosa in other bays are (quasi)stable to varying degrees. Local diet and feeding resources were found to be the key factor influencing the structure and parameters of Rapana populations in Sevastopol bays.
