AB  - The population parameters of <I>Macrobrachium vollenhovenii </I>(African river prawn) in the Lagos-Lekki lagoon system was estimated using a-24 month (May 2002 to April 2004) length-frequency data. The population parameters of growth; mortality and exploitation rates were, asymptotic length (L<SUB>8</SUB>) = 18.81 cm, growth coefficient (K) = 0.550, goodness of fit (Rn) = 0.195; total mortality (Z) = 2.67 year <SUP>1</SUP>, natural Mortality (M) = 1.35 year <SUP>1</SUP> Fishing mortality (F) = 1.32 year <SUP>1</SUP> and Exploitation rate (E) = 0.49, respectively. Recruitment pulse exhibited two peaks, one major peak and a minor peak which were in September to November and also in February. Length at  first  capture  L<SUB>c</SUB> as obtained from probability of capture analysis of the length-converted catch curve were 3.12 and 3.22 cm by logistic transformation and running average routines. The exploitation of this resource in the Lagos-Lekki lagoon system at the estimated F is almost at optium level as indicated by the E, as such this exploitation level should be maintained for sustainability.
