Abstract: Fishing effort and catches were leaded in three localities of the lower Bandama from July 2013 to June 2014. Tiassalé with 6675 outputs and 40.84% of the catch was the high production area. The highest catches are obtained in March, April and May while the lower catches are recorded in October and June. At Singrobo, fishing effort is estimated at 5942 outputs providing 31.70% of catches. In this area, two catches peaks are noted in December and April, but in October and January, these catches are very low. At N'zianouan, 5360 outputs were recorded for 27.46% of the total catch. However in this locality, the catch peaks are observed in March and May while the lower catch are noted in July and September. The fishing effort in these three localities generally progress in the similar way to the catches. The month with the highest catch has not absolutely the highest effort in these three areas. There is a significant correlation at p<0.05 between these two variables at on three sites. The conical fishing baskets are the most used devices in the lower Bandama River. They contribute to 57,11% of the total catch of the lower Bandama river.
