Abstract

Fish Trap is a fishing gear that can be used to catch various animals that live in the sea and one of them is a crustacean. Crustacean species that have important economic value that are widely managed are Penaeid shrimp (Penaeus sp) and lobster (Panulirus sp). In addition, blue crab (Portunus pelagicus) also the prima donna of Indonesia^s non-oil and gas exports. Meanwhile, deep sea prawns (Heterocarpus sp) are rarely utilizad because to catch them requires a fishing gear that is currently prohibited, namely trawling. Therefore, to be able to replace the function of trawling in capturing demersal biota, the use of deep sea traps was tested. The deep sea traps must have large dimensions in order to be able to catch large quantities of shrimp which are sufficient to cover operational costs, but the large dimensions will create transportation problems due to limited space on board. Therefore this trap is constructed to be folded so that its dimensions become smaller. Another problem encountered in operating at the bottom of deep waters is that the currents of sea water are quite strong which will make the traps with a large weight difficult to lift to the surface of the water. This problem can be overcome by using a floating trap operating technique on a bottom trap that has been tested in the waters of Pajenekang Island and Selayar Islands and has been successful.
