    Abstract

    The relative Y/R and BIR analysis indicated that increase in fishing effort and reduction in length at capture would increase yield, but Thompson and Bell yield-stock prediction model showed that this would result in a loss in terms of economic returns. Stock recruitment relationship on monthly cohort basis showed presence of Ricker type of relationship, which was better when mature females instead of total adult females, were taken as the spawning stock. Maximum recruitment was possible with 13 million spawners or 193 tonnes of adult females as standing stock biomass.
