Abstract
Various methods have been proposed to calculate MSY from biomass estimates but the classical approach of Gulland (1971). MSY = 0.5 M Bo is still widely used. despite overwhelming theoretical and practical evidence pointing to its limited value. jprobably due to confusion as to available alternatives. A review of alternative methods is presented and their applicability to species with high values of M discussed. A simple method is presented on how to incorporate other ecological and life history parameters into the estimation of sustainable yield from biomass and harvest rates. The proposed method is then placed in the context of provding advice to fishery managers
