No. 10/2011: The maximum economic yield management of an age-structured salmon population

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.
