The steady state distribution of the population levels of the species is generated and examined. Optimal harvesting strategies based on a social welfare function are studied. The results derived from constant effort harvesting and an effort adjustment policy are discussed. Qualitative results and interpretations are provided.enPeer Reviewed Journal Article10.1016/0025-5564(86)90033-7
