Underwater World With Natalia Avseenko, The White Sea, Russia

Fauna and economy
The sea hosts more than 700 species of invertebrates, about 60 species of fish, and 5 species of marine mammals. The fishing industry is relatively small, mostly targeting harp seal, ringed seal, herring, saffron cod, European smelt, Atlantic cod and Atlantic salmon. There is a developing seaweed industry.
The White Sea is an important traffic centre of northwestern Russia, interconnecting various economic regions and providing an outlet to the foreign routes. The White Sea – Baltic Canal links it through Onega Lake to the Baltic Sea and the major city and port of Saint Petersburg. The Baltic Sea, in turn, is connected by the Volga–Baltic Waterway to the Volga River, Black, Caspian, and Azov seas. The major ports on the White Sea are Arkhangelsk, Belomorsk, Onega, Mezen, Kem, Kandalaksha and Umba. Despite being frozen in winter, the sea remains navigable all year around because of deployment of icebreakers.
