Inverse Correlation between Ovarian Development of Atlantic Salmon ( Salmo salar) Smolts and Sea Age
In order to understand the factors which determine sea age of Atlantic salmon (Salmo salar), ovarian development of smolts was examined in 14 groups which varied in parental sea age, smolt age, and size. Parental sea age of smolts explained most of the variation in ovarian development. Smolts from o...
