Bioassay of the estuary waters of the Chernaya River (Bay of Sevastopol, Black Sea) using the brine shrimp Artemia (Crustacea: Brachiopoda)

The area of Sevastopol Bay is a heterogeneous system, with the estuary of the Chernaya River in the apical part. To assess the ecological status of various parts of the bay and estuary in the summer season of 2018, we determined the oxygen content, salinity, pH, Eh, as well as the proportion of naup...
