Findings of Longfin Baikal Sculpin Cottocomephorus inermis (Yakovlev, 1890) and Baikal Yellowfin C. grewingkii (Dybowski, 1874) in the Downstream Pool of the Boguchanskaya Hydroelectric Power Station

We present information on the findings of Baikal endemic species, the longfin Baikal sculpin Cottocomephorus inermis (Yakovlev, 1890) and Baikal yellowfin C. grewingkii (Dybowski, 1874), in the middle reaches of the Angara River (downstream pool of the Boguchanskaya Hydroelectric Power Station). Under conditions of active hydraulic construction on the Angara River, accompanied by a change in the hydrological regime and fish habitat conditions, further dispersal of the two species of Baikal sculpins of the genus Cottocomephorus is predicted in the river basin up to the mouth.
