Amphipods of the marine farms in Sevastopol coastal waters (Black Sea)
Amphipods are one of the main taxa of invertebrates inhabiting the structures of marine farms. On the collectors of oyster and mussel farms in the Black Sea, their density reaches more than 200,000 ind.·m2 of the projected surface of the substrate. Amphipods, being a valuable food source for a number of fish and invertebrate species, as well as a consumer of organic matter, can increase the productivity of the Black Sea coastal waters. This work is aimed at the evaluation of the qualitative and quantitative characteristics of amphipods, as well as their biodiversity on the collectors of marine farms. To assess the species composition, biodiversity, and density of amphipods, standard methods have been used; the density was calculated per m2 of the projected surface of the substrate, based on the geometry of the marine farm components. 17 species of amphipods have been identified on the marine farm components, the most abundant of them being Jassa marmorata Holmes, 1905, Stenothoe monoculoides (Montagu, 1813), and Microdeutopus gryllotalpa Costa, 1853. The total density of amphipods in one sample on the farm structures reached 211,919 ind.·m2 of the projected surface of the substrate. The components of marine farms can facilitate the increase in the biodiversity and improve the quantitative characteristics of amphipods, which would result in the growth of the productivity rates of the Black Sea coastal waters.
