    abstract = {The population dynamics of <I>Pellonula leonensis</I> the target clupeid in the Anambra flood river system was studied with samples collected from commercial artisinal fishers. 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<SUB>&infin;</SUB>) = 9.98 cm TL, growth curvature (K) = 1.3 year<SUP>-1</SUP>. The mortality parameters were: total mortality Z = 4.03 year <SUP>-1</SUP>, natural mortality M 2.77 year<SUP>-1</SUP> and fishing mortality F was 1.26 year<SUP>-1</SUP>. 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 E<SUB>max </SUB>were 0.641 and 0.630, respectively. The stock was not overexploited, since E&lt;E<SUB>max</SUB>.}
