The Influence of Different Baits and Funnel Elevations of Collapsible Pot to the Catch of Mangrove Crab
Keywords:
influence, bait, funnel elevation, mangrove crab.Abstract
A box-shaped collapsible pot still requires improvement in thebait and the funnel elevation for capturing mangrove crab. The study aimed to determine the most attractive bait quality for the crab and the easiest funnel elevation to cross by the crab. The research was conducted in both laboratory and field experiments. The laboratory experimentsexamined different quality of bait from yellow stripe trevally fish (Selaroidesleptolepis). The bait quality consisted of fresh fish, 12 hours soaked fish, and 12 hours decomposed fish. The laboratory experiment also observed movement pattern of the crab to funnel of the pot with elevations 20o, 40o, and 60o. Furthermore, the field experiments examined actual pot (experiment pot) with funnel elevations of 20o, 40o, and 60o.The results showed that the crabs selected fresh fish in 58.54%, 12 hours soaked fish in 24.39%, and 12 hours decomposed fish in 17.07%.
