Abstract

The purpose of this research is to analyze the feasibility of the catch of cantrang in the Strait of Makassar and Bone Gulf after the moratorium policy of the use of fishing equipment in the Fisheries Management Area of the Republic of Indonesia. The research was conducted in August 2016 - July 2017. The research was conducted at 3 locations namely in L1 (Takalar), L2 (Pangkep) and L3 (Palopo). The location of the study was determined deliberately by considering the presence of cantrang and the representation of the waters of Makassar Strait and Bone Gulf. The study sample consisted of 2 types: cantrang and dominant catch fish. The number of samples of cantrang vessels is 73 (seventy-three) both units with classification in L1, 44 (forty-four) both units, in L2, 24 (twenty four) both units and in L3, 5 (five) both units. Fish samples consist of 6 species of dominant fish of catchrang catch that is; Leiognathus sp, Parapeneuscyclostenus, Upeneussulphureus, Clupeaharengus, Sphyraena sp and Lethrinuslentjan the total number of fish samples as many as 1800 heads or 600 heads per research location. Parameters observed include; both size, mesh size nets, fish catch type, fish body circumference, fish body length, fish body weight, and fish gonad condition. Research result; (1) mesh size used by fishermen in the three research sites is smaller than 2 inches. (2) The type of fish catch is a mixture of palagis fish and demersal fish with the number of species as many as 28 species. (3) Lethrinuslentjan at all three locations, entering the catch-catching category with the percentage of catch in mature gonad condition above or greater than 50%. (4) Sphyraena sp, Clupeaharengus, Upeneussulphureus, Parapeneuscyclostenus and Leiognathus sp at all three entry sites in unacceptable caught categories with the percentage of catches under conditions having matured gonads below or below 50%.
