Abstrak: Collapsible trap is the most popular fishing gear to catch of mud crab. This fishing gear has weakness, because its construction was adopted from other country without any aclimatization with behavior of Indonesian mud crab. The main objective of this research is to determine suitable design of collapsible trap to catch the mud crab. This research consists of two steps. First step is called as research of trap parts. The objectives of this step are to determine suitable mesh size of trap entrance, suitable slope of trap entrance, shape and size of trap entrance, and suitable colour of shelter. Second step is called as new design trap trial. The objectives of this step are to obtain the most productive design of trap and to determine influence of lid instalation at the top of trap as a shelter. The method of all researchs are laboratory experiment. The result showed that the suitable mesh size of trap entrance was 1 inchi, the suitable slope of trap entrance was 40o, the suitable shape of trap entrance was square with height of 5 cm. The distance between wires was 2-3 cm. The colour that was choosen by mud crab was black. So, this colour could be used by the trap as a shelter. The catch number of four types trap were significantly different (Fcount= 95.52 > Ftab= 2.74). Most of mud crabs were caught in new design trap (B) (59.2% from total catch) and fewer crabs were caught by fishermen trap (N) (0,05% from total catch). This trap has dimension of 50 × 50 × 16 (cm). The catch number of trap with lid and without lid was significantly different (Fcount= 125.59 > Ftab= 4.41). The catch number of trap with lid was 89 crabs (96.7% from total catch). While, the catch number of trap without lid was 3 crabs (3,3% from total catch).

Abstrak: Mud crab captured by various fishing gears. Trap produces best quality catches, because of the catch remain alive. Research has been conducted in Legonwetan and Mayangan waters since April to May 2012, aiming to get productivity and selectivity crab of collapsible traps. Laboratory-scale research was conducted to gain corresponding trajectory entrance angle, materials, and determining escape gaps size. Modified gear is 70 cm x 50 cm x 35 cm (L x W x H), with ramp tilt angle 30° and 40° with escape gap sizes 4 cm x 6 cm and 5 cm x 7 cm. Furthermore, fishing trials were conducted to see catches composition. ANOVA and t test were used to determine difference between tested folding traps. The result shows that there are significant influence in the doorway tilt angle differences to the amount of crab catches (F = 5.458, P = 0.023 <α = 0.05). Doorway tilt angle of 30 ° produce more catch than 40 ° angle ((t hit = 4.407, P <0.05). In conclusion, crab folding trap with trajectory doorway tilt angle of 30° is more productive to catch crabs and escape gap of 4 cm x 6 cm effective to release juvenile crabs.
