Ecology of Margaritifera margaritifera (Bivalvia, Margaritiferidae) in the River Kamennaya, White Sea Basin, Russia
The conditions for cohabitation of juvenile Salmo salar and Margaritifera margaritifera in the River Kamennaya (River Kem catchment, White Sea drainage basin, Russia) were studied. The M. margaritifera population in the River Kamennaya contains about 1000 specimens. The only intermediate host capabl...
