Experimental fishing targeting marine crabs was conducted using crab pots baited with overripe banana locally known as “latundan”, which is a hybrid of Musa acuminata (Colla 1820) and balbisiana 1820), cardinal fish Apogon lineatus (Temminck Schlegel 1842). This done to assess the catch composition investigate effect baits on selective catching desired species, size, sex during trapping operations. Four bait treatments were used: no (NB), (BB), (FB), banana-fish combination (FB+). Results showed that FB+ caught comparable P. pelagicus FB in terms numbers, T. sima about same. Pots having NB or BB alone fewest The significant difference number when baits. Portunus (Linnaeus 1758) Thalamita (Milne Edwards 1834) dominated catches among comprising total 44.21% 18.95%, respectively. In size (carapace width), had smaller comparison FB+, but statistical detected. Moreover, gender neutrality for pelagicus, more females than males caught. shows combined has intraspecific properties towards some species. Furthermore, addition bananas seemed decrease non-target species overall high percentage means these may have extra-specific potential thus reducing undesired trapped pots. inclusion can be beneficial future studies resource management reduction utilization bait.
