Abstract

In this study, catch per unit effort (CPUE) of three different traps were subjected to a comparison being used for catching the common rudd (Scardinius erythrophthalmus) in the Anzali Lagoon, Iran. The capture efficiencies and the catch rates of the cylindrical pot, the opera house trap, and the hokkaido pot were compared during 2017. The results showed significant differences among the cylindrical pot, opera house traps, and Hokkaido pot. The Hokkaido pot yielded similar performances in stations 2 and 3; however, it differed in station 1. The opera house trap produced different performances in all three stations (P < 0.05), while for the cylindrical pot, the performance was similar in all the three stations (P > 0.05). In conclusion, the opera house trap proved its superior efficiency and is therefore recommended to be used for catching the common rudd in the Anzali Lagoon.
