Recently in the northwestern part of the Black Sea hypoxia in the near-bottom layers of the water has frequently occurred (Zaitsev, 1993). Although here it may be accidental in nature, it has a strong effect on structure of bottom communities (Salsky, 1977; Losovskaya, 1987) causing the death of many hydrobiont species, especially of attached organisms: mussels, barnacles, etc. In the course of evolution these organisms adapted, an Continue Reading »

As is known, the growth of animal is an important integral parameter, which characterize a degree of suitablety of the environmental factors for development of this species in concrete location. The growth rate of mollusks depends first of all on depth, quality of fodder base, regime of temperature and salinity of water, density of settlements, degree of a wave action and some other factors.
