Abstract

At Veraval, Otolithus cuvieri together with Pseudosciaena diacanthus and Otolithus brunneus contributes nearly 70% of total sciacnid catches. O. cuvieri is carnivorous in its feeding habits, subsisting mainly on prawns viz. Acetes sp., Solenocera sp., Hippolysmata sp. and teleosts. Intraovarian studies showed that the spawning period of O. cuvieri extended from November to April. Fecundity in this species varied from 1,05,454 to 3,55,913. The relationship between fecundity and length of fish, weight of the ovary and fish weight was estimated.
