Summary: | Abstract This chapter develops a sustainable economic yield harvesting model for the wild Atlantic salmon (Salmo salar) where the population comprises different age classes. It is shown that the weight-fecundity relationship of the spawning population, comprising two age classes, is crucial for the maximum sustainable yield fishing composition. In a next step the optimal selective fishing is replaced by an optimal non-selective fishing pattern, and the discrepancy between these two schemes is analyzed. |
