Estimates of growth, mortality, recruitment pattern and maximum sustainable yield of important fishery resources of Maharashtra coast

Abstract

The growth, mortality, recruitment pattern and MSY of important fishery resources of Maharashtra were estimated. The investigation revealed that out of 18 fish resources 11 are optimally exploited. The penaeid prawn resources which are the target species of shrimp trawlers are underexploited. Cephalopods appear to be optimally exploited. The present yield of fishes, prawns and cephalopods are 65083, 38404 and 11373 tons while the estimated MSY are 83025, 72460 and 10475 tons. The study indicates that additional yield of 62,926 ton can be obtained by increasing the efforts to the extent of 25% without any adverse effects on the total resources.
