This study is conducted in Oebelo waters, Central Kupang Sub-district from October to December, 2013. It aims to find out the fishing power of trap (ID: bubu) in different types toward mangrove crab catch. It uses observation method by experimental fishing for one month. The findings show that the caught crab consists of 6 species, i.e. Scylla serrata, S. transquabarica, S. olivacea, Portunus pelagicus, Charybdis granulata and C. anisodon which six of these species are caught in every trap type. The caught crab species with the highest proportion is Scylla serrata by 60 crabs (58.823%), then followed by the other species. Trap type having the highest abundance rate is conical type code B 2.3, then conical type code B 3.2 and followed by the other types. Trap code B 2.3 and B 3.2 is the trap prototype having the higher fishing power compared to the others. Trap having the highest CPUE value is conical shape type code B 3.2, followed by semicircular shape code C 3.2, cube-shaped type code A 2.2 and the other types.Trap engineering in this observed crab fishing is one of the important information to improve the trap construction design and mangrove crab fishing method by utilizing trap in the future.
