Incubation of the Eggs of Atlantic Salmon, Salmo salar , at Low Temperatures
Eggs of Atlantic salmon (Salmo salar) from the River Alta in northern Norway were subjected to three experimental temperature regimes during prehatching incubation. Two of these were intended to simulate possible temperature situations in the river after hydroelectrical development of its upper reac...
