Nonindigenous Species in the Far Eastern Seas of Russia

摘要

Purposeful studies of alien species were performed in the Sea of Japan (Russian territory) in recent decades; however, the Sea of Okhotsk and the Bering Sea received less attention, and the studies there were occasional, so the data are scarce. An annotated list of 66 nonindigenous species of various degree of acclimatization is presented for the first time for the Far Eastern seas of Russia. A scale for assessing ahen species status is also presented.
