Comparative in Effective of Mesh Size of Collapsible Crab Trap to Blue Swimming Crab Fishery at Kung Krabaen Bay, Chanthaburi Province
Abstract
Effective of collapsible crab trap to blue swimming crab fishery was conducted at Kung Krabaen Bay, Chanthaburi Province on March, July and November 2016 by using three mesh sizes in the bottom of collapsible crab trap with the mesh size 2 inch, 2.5 inch and 3 inch. The result found that collapsible crab trap with mesh size 2.5 inch can harvest blue swimming crab higher than collapsible crab trap with mesh size 2 inch and 3 inch. The production of crab were 750.17 g, 711.24 g and 667.68 g, respectively. The average production of by-catch was found highest quantity in trap mesh size 2 inch with 880.44 g. 2.5 inch and 3 inch mesh size trap were found in 764.63 g and 446.91 g. Sex ratios were 1:0.92, 1:0.39 and 1:1.13, respectively. The statistical analysis showed that no significance between sex ratio in each trap size. Size distribution of crab in trap mesh size 2 inch and 2.5 inch were found in range between 71-80 mm while trap with mesh size 3 inch was ranged in 80-90 mm. These results in this research can used for improving blue swimming crab fishery improvement project especially policy with increasing of mesh size of collapsible crab trap in Kung Krabaen Bay, Chanthaburi Province.
