Abstract
Lizardfish fishery in Veraval is mainly supported by Saurida tumbil. It is exploited by trawls and gillnets throughout the year. The length range of S. tumbil was found to be 15.20 cm to 39.90 cm. The length- weight relationship is described as slope ‘b’ 3.190 ± 0.060 for male and 3.267 ± 0.048 for female. It also confirms the growth is allometric in this species. The food was mostly comprised of fishes, shrimps and squids. Food and feeding analysis confirmed the carnivorous feeding behavior of this species. The overall sex ratio was 1.41. Absolute fecundity was 32,148 to 76,742 /kg body weight. Key words: Saurida tumbil, Lizardfish, Length-Weight relationship, Food and feeding habits, Sex ratio, Fecundity, Veraval coast.
