In this study, the capture efficiencies and catch rates of three different traps were compared for the blue crab Callinectes sapidus in Beymelek Lagoon, Antalya, Turkey. All gear was used simultaneously and in the same habitats. The mean catch per unit effort (CPUE) was determined to be significantly higher for hoop nets than for traps. Gear effectiveness was examined by comparing CPUE (CPUE as number of crab per trap per haul, and g per trap haul), mean weight of individual crabs, catch composition and width frequency distributions of the blue crab for each gear.
