Estimation of length-weight relationship and condition factor of two commercially important Lethrinus species, Lethrinus nebulosus and Lethrinus microdon along Thoothukudi coast was studied from January 2019 to December 2019. A total of 736 samples of the two species were subjected to morphometric investigation for evaluating their total length and total body weight and analyzed season wise. The results indicate an isometric growth pattern with growth exponent, b values of 2.90 and 2.84 for L. nebulosus and L. microdon respectively. There was a strong positive correlation (r = 0.99-1.0) between the length and weight of fsh samples examined while the coeffcient of determination (R2) varied between 0.97-1.0 during all four seasons. The relative condition factor (Kn) was 1.0 for both species while Fulton’s condition factor (Kc) was observed to be 1.52 and 2.08 for L. nebulosus and L. microdon respectively. Not Available |
