Spelman Strait is one of the potential reef fisheries. This study aims to examine the potential of reef fisheries in the Spelman Strait. The data used in this study are primary data to determine the abundance of reef fish and the use of PaST (Paleontological Statistics) tools to assess diversity, Evenness, wealth, and dominance indices. The results showed that live coral cover from all observation stations was 37.71%. The abundance of reef fish has been under pressure, the diversity index still has good but some families experience threats, the Evenness index value also still shows an even distribution but there are several families threatened, the wealth index still describes good species wealth, but the distribution is uneven, while the dominance index value illustrates that the condition of the coral reef ecosystem is under pressure. This condition is caused by destructive fishing so that the existence of some economically important targeted fish is threatened.
Reef fish in Spelman strait, Indonesia, is one of the fishery resources of considerable economic value. Unfortunately, there is still the use of unfriendly resources equipment (destructive fishing) that cause potential social problems. In this study, all components of the EAFM (Ecosystem Approach to Fisheries Management) composed of 6 domains, namely (1) fish stocks, (2) environment and ecosystem, (3) fishing techniques, (4) culture, (5) social, and (6) institutional are analyzed combining with MDS (Multidimensional Scaling). The main aim of this research is to find out the root solution for managing coral reefs in the coastal waters of Spelman Strait. The sustainability status review in the fishery resource domain, the environment and ecosystem domain, the fishery technique domain, the social domain, and the economic domain were respectively were 87.69, 88.17, 51.22, 51.61, and 72.67 which were in the category sustainable. Meanwhile, the sustainability status review in the institutional domain was 42.15, which was in the category of less sustainable. Institutions are the primary base for reef fishery protection in the Spelman Strait.
Erosi pantai yang parah di sebagian wilayah pesisir Kabupaten Karawang, salah satunya di Desa Cemarajaya Kecamatan Cibuaya, telah berdampak pada kegiatan sosial ekonomi masyarakat. Upaya untuk melakukan penanggulangan erosi pantai antara lain dapat dilakukan melalui rehabilitasi pantai dengan penanaman mangrove. Akan tetapi, pengetahuan, pemahaman dan persepsi masyarakat desa tersebut dalam pelestarian ekosistem mangrove masih rendah. Oleh karena itu, perlu diterapkan kegiatan sosialisasi pentingnya kelestarian ekosistem mangrove, khususnya di areal sempadan pantai untuk penanggulangan erosi pantai. Metode pelaksanaan kegiatan ini menggunakan metode sosialisasi observasional. Hasil kegiatan pengabdian kepada masyarakat ini memberikan manfaat yang besar bagi bagi pemerintah desa, lembaga pendidikan (sekolah) dan masyarakat setempat.
Spelman Strait coastal waters are marine waters rich in coral reefs and fish stocks. Reef fish resources are required for natural, ecological, social, economic and institutional fisheries management. One type of management owned by local fishermen is local reef-fishing expertise based on two fishing seasons (west and east monsoon). The research goal is to establish local knowledge as a method of sustainable management of coral reefs in Spelman Strait, Central Buton Regency, in support of development. The results obtained, the management of coral fisheries based on local knowledge (west and east monsoon) with the use of different fishing hooks, where the westmonsoon uses fishing hooks number 5-8 with the target family Serranidae and Lutjanidae (export quality) and large size, while the monsoon east of the use of fishing line numbers 15-17 with the target of all reef fish and the size of thedifferences in fishing habits may be used as effective management of reef farming.
