This study reveals that the crab size selectivity for small scale pot should be
concerned while species selectivity for commercial scale. Estimates of the catch
composition of Gulf of Thailand collapsible crab pot have highlighted issues of concern
within the fishery. The results showed that the by-catch for both types of operation has still been in
the level that we should take some mitigation measures. Although awareness of these issues can
be used to advise in the formulation of a bycatch management plan, for several issues there
is insufficient information on the scale of the problem. This highlights need for a programme
specifically designed to answer the outstanding questions. A stratified approach is required
to ensure that all fishing companies and fishing areas are adequately covered. Further,
seasonal trends in catch composition or discarding pattern should be monitored, such that
the efficiency of management strategies can be assessed.
