Abstract
One of the most important Factors on crayfish production in ponds is their economic catch method. The crayfish usually are harvested by fishing traps and so use traps with the highest fishing efficiency in the fishing effort is so importance. In this report four most common fishing traps, including Hokkaido, funnel, Opera house and cylindrical were evaluated. The results showed that the highest and lowest mean length of caught crayfish estimated in Hokkaido and cylindrical traps, respectively. It was also proved catch per unit effort on Hokkaido was significantly higher than funnel, opera house and cylindrical traps (p < 0.001). In totally, for commercial harvest of crayfish in ponds use of Hokkaido trap as a first priority are suggested.
