REPRODUCTION OF THE BROWN TROUT (SALMO TRUTTA L.) AND ATLANTIC SALMON (SALMO SALAR L.) IN SMALL RIVERS (WHITE SEA DRAINAGE BASIN)
Some aspects of the reproduction of salmonid fish in the small rivers Ol’khovka and Krivoy Ruchey (White Sea drainage basin, Tersky coast of the Kola peninsula), including downstream migration of brown trout and atlantic salmon smolts, as well as the distribution of juveniles of these species across...
