The maximum sustainable yield management of an age-structured salmon population: Fishing vs. conservation
This paper develops a sustainable 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 young and old fish, is crucial for the maximum sustainable yield fishing composition. First, the optimal harvest is found when fecundity is approximate...

متن کاملInvestigation of Sardinella Sindensis (Day, 1878) Stock Status Using the Catch-Maximum Sustainable Yield Model in the Southern Waters of Iran (Persian Gulf and Oman Sea)
Among the various species of small pelagic fish, Sardinella sindensis (Day ,1878) has high economic and ecological importance and is one of the most important species exploited by fishermen. In recent years, the catch rate of this species has increased, and due to the limited data available on its stock in southern waters, it is not possible to use models based on the complementary data to asse...
