Catch Status and Trend Analysis of Brachyuran Fisheries in the Gulf of Thailand
Abstract
Long term catch data of three groups of marine crabs viz., Portunus pelagicus, Scylla spp. and other food crabs in the Gulf of Thailand (GoT), during the 1981-2013 (33 years) were used for assessing on catch status and trend analysis. The results showed that all crab groups have been commercial fishing since 1981 and increasing steadily in catches overtime. Overexploited status was found in the last dataset (i.e. 2013) for all crab groups. For trend analysis, there are unique catch trends for each crab group. First, catch trend increasing and vice versa in P. pelagicus, i.e. the catch increased continually from 1981 to 1998 and after that decrease until the last dataset. Second, for Scylla spp., catch increased continuously from 1981-1993. After that, annual catch showed a high variation and resulted in non-significantly trend. Lastly, for the other food crab group, catch trend showed continuous increasing from 1981-2013. The results also implied that fishing pressure is the major cause in fluctuations in marine crab catch and resulting unstable crab populations across the GoT.
