Marine Ecological Journal| Summary: | Data on the quantitative development of Mytilus galloprovincialis on the Karadag rocks (south-east coast of the Crimea, Black Sea) in 1981, 1998 and 2009 were presented. The long-term (since 1938) changes of abundance of M. galloprovincialis and Mytilaster lineatus in this biotope were analyzed. In 1980-1990 years an increasing of the quantitative development of rock mussels in 70 times are revealed. Currently the number and biomass of mussels reduction of life expectancy of individuals are decreasing, while rejuvenation population had found. The observed fluctuations in the mussels numbers are the result of global processes of eutrophication level changes. Predatory of snail-invader Rapana venosa is secondary factor affecting on mussels settlement. |
