Efficiency of natural and artificial reproduction of Baltic salmon as the result of peculiarities in its freshwater life period

The population structure and dynamics, the distribution, behaviour, feeding, growth, smoltification and descent of salmon (Salmo salar) fry in the Latvian rivers including parrs and smolts, are described. The ecological peculiarities of the freshwater period of life are studied, and main factors det...
