Through out the study, the comparison of crab pot operation between small and commercial
scale is shown in Table 1. Between both types of the pot fishing, only the pot was same but all others
were different (Table 1).
The catch composition by number from a small scale boat operation is shown that the majority
catch was blue swimming crab, as 72.4-91.3%. Others species also were caught and being considered
as bycatch, both commercial and no commercial value. Ridged swimming crab Charybdis natator and
smoothshelled crab Charybdis affinis were dominant bycatch species through out the study.
The catch composition by number from a commercial scale boat operation is shown that
the majority catch was still blue swimming crab, but smaller numbers than small scale, as 21.2-51.6%.
Others species also were caught and being considered as bycatch both commercial and no
commercial value with larger numbers than small scale both in quantity and quality (species). Threadfin
bream, mantis shrimp, grunter, filefish and octopus were dominant for commercial valuable species
while squared-shelled crab, smoothshelled crab and goby were dominant for low/less valuable species.
