    abstract = {The present study was conducted to understand the population parameters of <I>Labeo senegalensis</I> in Benin. Growth and mortality parameters, exploitation rates and annual recruitment patterns were estimated from monthly length-frequency samples between April, 2005 and March, 2006 for <I>Labeo senegalensis</I> in the Oueme river. Total length of the sampled 1436 fish ranged from 6.3-52.7 cm. The Von Bertalanffy Growth Function (VBGF) was fitted to the 12 consecutive month&#146;s length-frequency data to obtain a VBGF with the following parameters: L&infin; = 57 cm TL, K = 0.30 year<SUP>-1</SUP>. The growth performance index (&oslash;') was calculated as 2.99. The total mortality estimates from the catch curve analysis was Z = 1.47 year<SUP>-1</SUP> with a natural mortality M of 0.68 year<SUP>-1</SUP> for a mean environmental temperature of 28&deg;C. The fishing mortality F estimates was 0.79 year<SUP>-1</SUP>. The maximum of recruitment was recorded in June to September, indicating recruitment of one cohort year<SUP>-1</SUP>. The estimated potential longevity T<SUB>max</SUB> was 10 years. The exploitation ratio was 0.55 indicating that the <I>Labeo senegalensis</I> stock is on the verge being overfished. The results are discussed and compared to previously available information on <I>Labeo senegalensis</I> in others rivers.}
