Abstract
In the area of the village. At the end of October 2020, there was a massive release of bivalve mollusks in a coastal strip 1.2-1.5 km long, 1.5-15 m wide. To determine the causes of this phenomenon, anthropogenic (presence of a landfill located near the area of mollusk releases) and natural (strong storm, spring tide and elevated temperature) occurred water) factors. On the entire coast, only two species of bivalve mollusks Spisula voyi and Siliqua alta were found in the ratio of the number and mass of species 0.59:0.41 and 0.65:0.35, respectively. The size, age and number of commercial shellfish washed ashore are considered. On the surveyed section of the coast (S = 6075 m2), the total amount of Siliqua alta, aged from 2 to 9 years, was estimated at 16.6 tons, Spisula voyi, aged from 2 to 10 years, was estimated at 31.2 tons.
