Incubation of Eggs of Atlantic Salmon ( Salmo Salar ) from Different Norwegian Streams at Temperatures below 1 °C
Atlantic salmon (Salmo salar) eggs obtained from fish from five widely separated localities were incubated from fertilization until hatching at mean temperatures of 1.0 and 0.17 °C. The results indicate that an existing model used to predict time of hatching in Atlantic salmon at temperatures greate...
