[Using the capture-mark-recapture method for quantitative assessment of populations of molluscs in two sites in Lampsar (Valley of the Senegal River)].
The authors have made an estimate of the number of mollusc by the capture-mark-recapture method at two sites in the Valley of the Senegal River. This quantification is necessary to track the effect of the introduction in one of the sites of a native shrimp Machrobrachium vollenhovenii, predator of mollusc. The populations of two study sites were approximately 1,800 and 1,500 individuals with coefficients of variation of about 30%.
