About 13 consecutive months length-frequency data was analysed using the FiSAT program to obtain the following parameters: growth parameters were as follows: asymptotic Length (L) = 9.98 cm TL, growth curvature (K) = 1.3 year-1. The mortality parameters were: total mortality Z = 4.03 year -1, natural mortality M 2.77 year-1 and fishing mortality F was 1.26 year-1. Exploitation rate E was 0.31. T he fish exhibited the bimodal continuous recruitment pattern. The Knife-Edge selection and Selection Ogive procedures for relative yield/biomass per recruit showed that Emax were 0.641 and 0.630, respectively. The stock was not overexploited, since E<Emax.} }
