- Blue swimming crab (Portunus pelagicus) fishing using traps is one of the common techniques to get the high economic value of crabs. The traps use natural bait as an attractant. However, the limited availability of natural bait and degradation of protein content during the soaking time of traps affecting the effectiveness of fishing activities. One alternative that can be used to solve the problem is the application of a light-emitting diode (LED) as artificial bait. This study aims to determine the suitable light color for blue swimming crab fishing using a collapsible trap. The research was conducted in a laboratory using a rectangular tank with three different c olors of LED including blue, green, red, and dark conditions as controls. The response and behavior of the crab were analyzed descriptively. The results showed the crabs have the highest response to the blue LED compare to the other colors. However, the fastest crawling speed of 4.67 cm/second was found on the green LED. The blue LED are a suitable color for application in collapsoble traps because of the higher number of crabs and the number of crabs that respond positively to light sources compared to other colors.
