Also in the Ussuri and Sungari, China. Four populations are recognized in the Amur River basin: one lives in the estuary and coastal brackish waters of the Sea of Okhotsk and Sea of Japan, second is found in the lower Amur, third in the middle Amur, and fourth in the lower reaches of the Zeya and Bureya rivers in the Russian river banks (Ref. 40142 ). Two ecological morphs are present in the estuary population, the 'freshwater' and the 'brackish' water forms (Ref. 40142 ).
