Stock assessment of the brown mussel, Perna indica (Kuriakose and Nair) from the southwest coast of India

Abstract

Estimated the population parameters and the maximum sustainable yield (MSY) of the brown mussel Perna indica from the southwest coast of India. Analysis using the length based Thompson and Bell's method indicated MSY of 853 t, F_^,^ (X =) 1.4875 and mean biomass 961 t. Though the estimated annual average catch is less than the MSY, an increase in effort is not recommended since it will not lead to a considerable increase in the catch.
