Abstract

ABSTRACTThe use of capture technology is not environmentally friendly and low public awareness to restore the Mud crab (Scylla sp.) that still poses a threat to small crab in natural resource conservation. The use of a gap for passage of the mud crab trap folding is one of the fishing technology innovations that will increase the size of crabs caught making it more environmentally friendly. This study aims to determine the size, shape and position of mounting an effective escape gap on collapsible traps for mud crabs that have not passed a decent catch. The method used was a laboratory experiment conducted on Fisheries Department UNTIRTA using escape gap is 2 boxes (50x50) mm and rectangular (60x36) mm mounted on the top and bottom position of the mouth traps. The results showed that the folding rectangular traps more effective mud crab that has not passed a decent escape capture by the percentage reaches 65%. Position mounting a more effective escape gap is at the bottom position of the mouth traps with crab escape frequency percentage of 54%.Key words: collapsible trap, escape gap, fishing technology, mud crab-------ABSTRAKPenggunaan teknologi penangkapan yang tidak ramah lingkungan dan rendahnya kesadaran masyarakat untuk mengembalikan kepiting bakau yang masih berukuran kecil memberikan ancaman terhadap kelestarian sumberdaya kepiting di alam.
