The Fishing of Mugilidae in Grand-lahou Lagoon (Ivory Coast): Analysis of Fishing Organisation, Captures and Fishing Effort. Sixteen sites, around the lagoon, have been investigated from April 2009 to March 2011. At the pass, fishing with sparrow hawks is mainly done by Ghanaians. On the other sites of lagoon, indigenous fishers are dominant and use gill-nets. Ocean area, with more than 50% of activities and 60% of captures, is the place where the highest production is realized. The site around the pass provides 25% of activities and 20% of capture. At the pass and in the continental area of the lagoon, captures remain inferior to 10%. There, the peak of captures is registered in July and the lowest ones from February to April. On the others sites of the lagoon, two peaks can be observed in December, May and July. From the end of July to the end September, captures from ocean and the pass remain very low. During this period, fishing is interrupted on the others sites for Mugilidae are rare and water is desalinated because of continental waterways pouring out in the lagoon. Fishing efforts peaks don't always coincide with capture peaks even if during high captures period, fishing effort values are very high.
