  This study examined some aspects of population dynamics of 1776 specimen of S. maderensis (Lowe, 1988) from Liberian coastal waters, from April 2013 to September 2013 (total of six months) using the FiSAT II for analysis. From the results, the growth was assumed to follow the von Bertalanffy growth function with asymptotic length (L∞) and the growth coefficient (K) estimated at 44.63 cm total length and 0.38 year-1 respectively. The growth performance index, longevity and the theoretical age at birth (t0) were estimated as 2.88, 7.51 years and -0.387 year-1 respectively. The length at first capture (Lc50=13.99 cm) was lower than the length at first maturity (Lm50=29.75 cm), an indication that most of the harvested stock were juveniles. Instantaneous rate of total mortality, natural mortality and fishing mortality were estimate.. View More»
