Effects of entrance design on catch efficiency of Hokkaido pot: a field experiment in Anzali Lagoon, Iran
In this study, the catch per unit effort (CPUE) of Hokkaido pot was compared with the oriental river prawn (Macrobrachium nipponense) in the Anzali Lagoon, Iran. Capture efficiencies and catch rates of the Hokkaido pot were compared during 2015. This field experiment investigated the effects of different entrance designs on the catch efficiency of Hokkaido pot (H1) by fishing with commercial Hokkaido pot (H2) (entrance inclination angle and number were different). The experimental pot was identical, in size and design, to commercial pots, apart from some difference in the entrance (Pots: H1: α = 45° and 90°, three entrance; H2: α = 90°, one entrance). Significant differences were detected between pots of H1 and H2 (P < 0.05). H1 pot yielded more than H2; however, no significant differences were recorded in the mean total length or the frequency distributions of the total length between both pot types (P > 0.05).
