ABSTRACT
To understand the overall changes in spawning, fecundity, length at first maturity and sex ratio of the species Saurida tumbil and Saurida undosquamis inhabiting along North West coast of Indian EEZ were studied during 2010 to 2014. In both the species, the spawning season is single but prolonged, extending from June to March in case of Saurida tumbil whereas in S. undosquamis, it is observed during September to May. Length at first maturity in S. tumbil was between 29-31 cm and in S. undosquamis, 25-27 cm. Male to female sex ratio was found to be 1:0.7 in both the species. Maximum fecundity of 85,359 ova was observed in S. tumbil at the length of 44.6 cm and of S. undosquamis 11,395 ova in 41 cm fish. The peak GSI values were obtained in the month of November (3.83) for S. tumbil and for S. undosquamis in October (4.38).
Key words: Spawning, Fecundity, Length at first maturity, Sex ratio, Gonado-somatic Index (GSI)
