ABSTRAK

This study aims to look at the level of damage to coral reefs based on Chaetodontotidae fish and biodiversity of Chaetodontidae fish on Maitara Island. This research was conducted in April to May 2019 at 2 stations. Collecting coral reef data using the Line Intercept Transect (LIT) method which is placed parallel to the shoreline, while Chaetodontidae fish uses the Visual Method Census method. During the study, 20 species of Chaetodontidae were found, representing 2 genera; namely Chaetdon (15 species), and Chelmon (5 types). Fluctuations in the index of diversity, diversity and dominance can be used as indicators of damage to coral reefs. Diversity (H') ranges from 0.67-1.01, the percentage of live coral cover between 10.80% to 15.30%. The damage of the Coral Reef of Maitara Island is in the damaged category based on the Minister of Environment Decree of 2001. The correlation between the percentage of live coral and Chaetodontidae fish is positive, the determinant coefficient of each species is more than 95%. Low species diversity and individual dominance of one type of Chaetodontidae show that coral reef damage has been caused by anthropic activity, so the loss of most of the main meal of Chaetodontidae fish is coral polyps.

This research was experimental fishing methods and regression analysis to examine the effect and relationship between biophysical parameters namely sea surface temperature and chlorophyll-a and the results of small pelagic fish conversations in Ternate Island, the results of the study showed that the biosphysical parameters including sea surface temperature (SPL) and chlorophyll-a have a significant influence on the distribution of small pelagic fish, with the correlation coefficient values of each sea surface temperature parameter and chlorophyll-a with the results of the pelagic fish tagging are 0.6121 and 0.7042

Penelitian ini bertujuan untuk (1) Mengidentifikasi Karakteristik transformasi industri penangkapan yang berlangsung pada komunitas masyarakat nelayan di Desa Panambuang Kec. Bacan Selatan terkait dengan perkembangan investasi, teknologi alat tangkap dan manajemen, (2) Menganalisis proses berlangsungnya transformasi ikatan Patron-klien, akibat terjadinya kelompok kerja pada alat tangkap pole and line, (3) Menganalisis strategi masyarakat nelayan dalam pengembangan usaha perikanan tangkap yang berkelanjutan ditengah terus berlangsungnya proses diferensiasi sosial, komersialisasi ekonomi akibat transformasi teknologi alat tangkap. Hasil penelitian menunjukkan bahwa transformasi teknologi alat tangkap pole and line pada waktu yang akan datang diharapkan dapat memberikan dampak yang baik dalam upaya memperoleh hasil tangkapan yang optimal. Hal ini dapat dipahami mengingat dalam pelaksanaannya di lapangan bahwa akses kebutuhannya terhadap sumberdaya perikanan sangat dipengaruhi oleh kekuatan modal yang dimiliki oleh pemilik kapal. Mekanisme patron klien sebagai (institusi ekonomi) tidak bisa memberikan solusi bagi pemerataan kesempatan dan akses yang merata terhadap sumberdaya alam. Bila hal ini terus berlangsung dan sumberdaya ikan terus menurun karena tingkat penangkapan yang tinggi, dikhawatirkan dapat menjadi pemicu pecahnya konflik horizontal antar kelompok-kelompok nelayan
