Abstract
When Beroe cf ovata appeared in the Sea of Azov, it rapidly decimated Mnemiopsis here, and a partial restoration of the pelagic food chain followed. Experiments were conducted with Beroe, to test for its salinity tolerance and temperature range, using Sea of Azov water, and Caspian water, which has a distinct ionic composition. Beroe is capable of surviving in both, and is limited only by the salinities of the extreme northern Caspian, 7.5‰ apparently being the limiting concentration. We argue that the stenophagous Beroe can be safely introduced to the Caspian, in order to save the fisheries and other components of the pelagic food chain there.
