| Abstract |
The fouling structure of the Japanese scallop was studied in Amursky Bay near Vladivostok. Fifty-six species of hydrobionts were identified. Barnacles prevailed in biomass and population density, and algae dominated in the number of species. The change in the dominant barnacle species observed in the fouling was caused, apparently, by the reproductive strategy of Hesperibalanus hesperius, which is more labile than that of Balanus rostratus, and by the anthropogenic impact on the ecosystem of the bay. The fouling was marked by bivalve and sea anemone species resistant to silting and pollution. The main groups of epibionts were classified as suspension feeders, and as selective detritophages that are characterized by their type of feeding. The total infestation of shells of the Japanese scallop by boring polychaetes and the depressed condition of most mollusks and algae evidenced the unfavorable ecological situation in the area surveyed. |
