Abstract

This study aimed to analyze the status of blue swimming crab resource in the Gulf of Thailand. Blue swimming crab bioeconomic model was estimated using time-series data from 1990-2012. The results from the analysis using backward bending supply curve having price varied with catch of blue swimming crab fisheries showed that, the maximum economic yield (MEY) required an effort of 19,477 boats, compared with the maximum sustainable yield (MSY) at 31,150 boats, open access equilibrium (OA) at 38,391 boats while the actual effort in 2012 was 49,751 boats. The MEY catch was 26,113 tons compared to the MSY of 30,371 tons, open access of 28,743 tons while the actual catch in 2012 was only 24,741 tons.  Blue swimming crab resource in the Gulf of Thailand had been overexploited, and the stock had been degraded.  This was proved by, the actual catch in 2012, which was lower than both maximum sustainable yield and maximum economic yield in spite of the higher fishing effort.
