The present article considers the distribution and hybridization of Mytilus trossulus and Mytilus galloprovincialis along the Russian coast of the Sea of Japan, mostly in Peter the Great Bay (PGB) and more northern Kievka and Preobrazenye Bays (Fig.
Adult mussels were collected from different localities along the Russian coast of the NWSJ in PGB and adjacent areas, starting from Possjeta Bay, with Troitsa and Vityaz Bays, in southwestern PGB to Kievka and Preobrazenye Bays to the north of PGB (the latter two are formally outside PGB) (Fig.
The species distribution in Amurskiy and Ussuriysky bays, Livadia Inlet, and Kievka and Preobrazenye bays is analyzed here for the first time using biochemical genetic, molecular genetic, and morphometric characters.
However, the DS2 sample set shows as well a hybrid occurrence in three settlements, in Possjeta Bay (Zarubinol2, 24%), in Kievka Bay (Kievkal2, 15%), and in Amurskiy Bay (Lazurnaya, 9%), where the proportion of M.
A considerable hybrid frequency of up to 21% in the sample from Kievka Bay is another interesting find here in 2011 (Kartavtsev et al.
