Underwater World With Natalia Avseenko, The White Sea, Russia

Between the 15th and early 18th centuries, the White Sea provided the major trade route to Russia. This role decreased later with the foundation of Saint Petersburg, which opened a more favorable connection via the Baltic Sea. From the 1920s, most Russian sea shipments were diverted from the White Sea to the new port of Murmansk, where the waters did not freeze in winter.
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.
