Abstract
The trap is one of the fishing gear used by fishermen to catch crabs. The fishermen used a trap to catch the crab with natural bait and are currently not equipped with escape gaps. The purpose of this study is to determine the effectiveness of eco-smart fishing traps (ESFT) for catching blue swimming crab (Portunus pelagicus) on a laboratory scale. A laboratory experiment was conducted from July to December 2020 using a rectangular tank with four different traps. We used a control trap (natural bait), ESFT-A (trap with rectangular escape gap and blue LED), ESFT-B (trap with blue LED and net wall of 2 inches), and ESFT-C (trap with blue LED and net wall of 2.5 inches). Each treatment used 30 different swimming crabs. Data were analyzed descriptively, and one-way ANOVA was used to determine the most effective design of the collapsible trap. The highest number of responded crabs was found at the ESFTB, which was 23 individuals with the fastest response time of 56.68 seconds. The highest percentage of caught crab was found in control traps at 60%. Moreover, ESFT-B and ESFT-C generated percentage of caught crab is 30% and 40%, respectively. The highest percentage of crab escape was found on ESFT-B, as big as 50%. Due to the crab caught and crab release percentage, we decided that ESCFT-B is a suitable design to increase the productivity and efficiency of swimming crab fishing.
