摘要

A detailed fishery characteristic of Lethrinus lentjan was carried out from July 2011 to June 2012. The data were collected on weekly intervals for studying the length-weight relationship, growth parameters, recruitment pattern, spawning seasons, fishing pressure and MSY. A total of 5062 specimens of L. lentjan are collected during the study period to estimate the above said parameters. The total annual catch of L. lentjan was 7799.208 tonnes are obtained by 52,210 boat days. The CPUE was found to be high during the month of October and December, for L. lentjan and estimated MSY is 10683.84. The difference between the annual catch and MSY is 2884.632 tonnes. Study on maximum sustainable yield indicated that L. lentjan is underexploited. To maximize the catch, an increase in the fishing effort to 36.98 % with 31999 boat days may be made, the species, to get the Maximum Sustainable Yield.
