DISTRIBUTION AND SOME ECOLOGICAL AND BIOLOGICAL CHARACTERISTICS OF MYTILASTER LINEATUS GMELIN, 1789 OF THE MIDLE CASPIAN SEA
OSMANOV Magomed Magomedovich,
ALIGADZHIEV Murad Mukhtarovich
It was established that the distribution of the mytilester in the Caspian Sea took place because of the number of factors: the nature of the soil, the range of salinity and competition with the autochthonous species. The biocenosis of the mytilaster creates an effective belt of biological filter and serves as a refuge for numerous intrabionts. Displacing the autochthonous Dreissena into the deeper layers of the sea, Mytilaster lineatus becomes the dominant species of fouling cenoses in the coastal shallow part of the Middle Caspian. The age of the mollusks in the studied areas ranges from 0 to 4 years old, while the number of individuals of older age groups increases with depth. The relationship between the length of the shell and the body weight of the mollusk is approximated by the power equation: Y = axb.
