Extract

Only a small number of salmon smolts (Salmo salar) that leave the river for the sea return for spawning (Calderwood, 1930, p. 180; 1931, pp. 36, 56; Menzies, 1931, p. 60; and others). The large loss of adolescent fish seriously affects the stock of salmon in the rivers, so that the question of possible causes of the death of salmon in the sea is one of some practical interest.
