This study presents the results of the experiment having the aim to evaluate the attractivity of the different light color for the climbing perch (Anabas testudineus). Catches by traps equipped by lamps emitted six different light colors (red, green, yellow, blue, orange and white) were compared with catches of control traps without any lamps. Each light color was estimated in three illumination levels. The trials consisted of 140 trap hauls per lamp type with a submersion time of 10 h. Basically A. testudineus positively responded to all colors of the lamps tested. The light traps were considerably higher in the number of catch as compared to the control (P<0.05), except yellow and orange traps. A total of 608 individuals of A. Testudineus (7.523 g) consisted of 210 males (2.808 g) and 398 females (4.715 g) were investigated. The size of catch ranged of 60-170 mm total length (TL) and 4-84 g weight. The average CPUEs were ranged from 0.04 to 2.36 fish trap-1 night-1. While the average YPUEs were from 0.32 to 40.76 g trap-1 night-1. The mean condition factors of male and female were 1.41±0.18 and 1.52±0.25, respectively, indicating fish in good condition. The positive group responses of fish were more pronounced at the length sizes between 100 and 109 mm TL. Negative allometric growth pattern (b=2.7255-2.8247) was observed in A. testudineus, implies that culture strategy should be developed. In addition, efforts to collect them from the wild for breeding and commercial purposes may benefit from this research.
