Changes in catch‐per‐unit‐effort (CPUE) were evaluated when all the sluice gates on the Pak Mun Dam, Mun River, Thailand, were opened between July 2001 and June 2002. CPUE ranged from 0.38 to 1.70 and 0.61 to 2.71 kg fisherman −1 night −1 , downstream and upstream of the dam, respectively. No statistical differences ( P > 0.05) among months were observed in both areas. The monthly percentage index of relative importance (%IRI) of the fish species caught varied between months.
