Abstract:  Study on maximum sustainable yield along Thoothukudi coast indicated that L.lentjan is underexploited. The L∞, K and t0 value of L.lentjan were 78.8 cm, 0.37 year-1 and -0.68 year respectively. The K value of L.lentjan was relatively higher inferring slow growth rate of this tropical demersal fish species. Total instantaneous mortality (Z) of L.lentjan was 1.28 year-1 and the estimated Fishing mortality was 0.73. Recruitment of  L.lentjan was recorded in throughout year with two peaks in July – August, 2011and April, 2012.
