Fecundity

The annual catch of Penaeus (Melicertus) canaliculatus varied from 353 to 7090 kg with an average of 2009 kg during 2003-2007. The fishing season was from January to June. The total length of males was 91-195 mm and females 86 to 230 mm in the fishery. Females dominated the catch. Crustacean remains were dominant in stomach contents (63.9%) followed by molluscan shells (22.5%). About 78% of females were in spent stage of ovarian development and 5.7% were with ripe ovary. The peak spawning months were February and June. The fecundity varied from 1,55,400 to 2,36,600 eggs with an average of 1,85,733. L ∞ and K were 200 mm and 1.9 for males, and 237 mm and 2.0 for females, respectively. Length-weight relationship was Log W = -5.1287+2.99997 Log L for male and Log W
