Abstract
The Fisheries Management Area No. 713 of the Republic of Indonesia is covering the waters of Macassar straits, the waters of Bone Gulf, the Flores Sea and the Bali Sea. This Fisheies Management Area 713 was declared by the government through Ministery of Marine Affair and Fisheries Regulation no 18/PERMEN-KP/2014. The potential fish resources of this area is estimated at about 1.777.854 ton/year, comprised by a principal commodities of fisheries resources group in 1) large pelagic fishes, 2) small pelagic fishes, 3) demersal fishes, 4) coral fishes, 5) penaeid shimps, 6) lobsters, 7) mangrove crab, 8) swimming crab, and 9) squid.
Based on the Maximum Sutainable Yield calculated for each group of the resourcs, a Total Alloable cactch (TAC) for each group of the resources were decided, started from the lowest TAC of 742 ton/year for the lobster to the highest TAC of 516,046 on/year for the large pelagic species group.
Catch data reported by the PUSDATIN (2020) shows that the large pelagic fishes in the area has reached the over exploited stage, so as the small pelagic fishes, the coral reef fishes, the lobster group and the squid. The rest of the groups, i.e the demersal fishes, the penaeid shrimps, the mangrove crabs and he swimming crabs are reported to be fully exploited. This stage implicates th resources should be firmly monitored, and the effort should not be furtherly increased.
The catch per unit of effort (CPUE) analyses on 5 year data trend (from 216 to 2017) of the mackerel fishes (Scomberomorus spp) shows that the species is having a trend of decreasing significanty. ). The decreasing trends of the fisheries production and the cpue in the area the indicators of a ruining fisheries resources. The management also has not put the gear selectivity factor and the effect of fishing on the ecosystem. The next and continuing management measures should include a firmly banning of the trawl activities, beach seining and trammel nets.
