Abstract

The growth parameters of Stolephorus devisi are estimated by Gulland and Holt Plot as Lα 113 mm, K 0.0056/day and to at—36 days. The species reaches 101 mm total length at the end of one year. The length-weight relationship is found to be w=0.00000 625 L'""". The species attains firs t maturity at a length of 62 mm. The major spawning is from October to February. Juveniles are found from February to May. Fecundity estimates are correlated to the length of the fish. A steep fall in relative condition (Kn) at 62 mm coincides with the length at first maturity. The low Kn values beyond the length at first maturity appear to be due to protracted spawning season of this species.
