Abstract

This study was aimed at revealing the structure of seagrass community in the coastal waters of Bahoi Village, West Likupang Sub-district, District of North Minahasa, North Sulawesi Province. Samples collection was conducted during the lowest tide period by deploying line transect and quadrate. Eight species of seagrasses were identified on this study, including species as follow: Enhalus acoroides, Thalassia hempricihii, Cymodocea rotundata, C. serrulata, Syringodium isoetifolium, Hlodule pinifolia, H. uninervis and Halophila ovalis. The highest density value ( 112.16 individual/m2) was calculated from transect III data on S. isoetifolium species. In term of relative density value, S. isoetifolium also has the highest value (35.176 %). Index dominance (C) was calculated as well from transect III data (0.477) while the highest diversity index  (H’) was calculated from transect I data (1.724).

Abstract

Lembeh Island is a small island part of the minicipality of Bitung, It is an area that supportincluding the category of small island, but it is an area that support community life in the mainland who mainly living as fishermen. Those fishermen generally made coral reef ecosystems as a location for  fishing. This research is aimed to provide information such as ecological conditions and states of coral reef, that  can be used appropriately in planning and decision making for the development of Lembeh Island waters, especially in the management of coral reef ecosystems. Intern of coral cover Lembeh island can be categorized in good condition and the state of coral reef management can be seen from the utilization activity that still good but tend to degrade over time. The implication, shows that the management and development of today tend to cause less sustainableto coral ecosystems. Keywords : Lembeh Island, coral reef, manajement, sustainability   A B S T R A K Pulau Lembeh merupakan pulau di Kota Bitung, termasuk kategori pulau kecil, tetapi merupakan kawasan yang menunjang kehidupan masyarakat di daratan utama, Masyarakat Pulau Lembeh yang berprofesi sebagai nelayan, umumnya menjadikan ekosistem terumbu karang sebagai lokasi penangkapan ikan karang. Penelitian ini dapat memberikan informasi berupa kondisi ekologi serta status pengelolaan ekosistem terumbu karang, sehingga dapat digunakan secara tepat dalam proses perencanaan dan pengambilan keputusan guna pengembangan perairan Pulau Lembeh, khususnya dalam pengelolaan ekosistem terumbu karang di masa mendatang. Kondisi terumbu karang Pulau Lembeh berdasarkan tutupan karang batu dapat dikategorikan baik, dan status pengelolaan terumbu karang dilihat dari kegiatan pemanfataan saat ini masih baik tapi cenderung menurunkan kualitas kawasan.  Implikasinya, memperlihatkan bahwa pengelolaan dan pembangunan saat ini cenderung ditata ke arah kurang berkelanjutan. ________________________________________________________________ Keywords : pulau lembeh, terumbu karang, pengelolaan, keberlanjutan _____________________ 1 Alumni Program Studi Manajemen Sumberdaya Perairan FPIK Unsrat 2Staf Pengajar Fakultas Perikanan dan Ilmu Kelautan Universitas Sam Ratulangi 3;Staf Pengajar Fakultas Perikanan dan Ilmu Kelautan Universitas Sam Ratulangi

Abstract

This study aims to provide information about coral reefs condition in Poopoh waters and as input For related stakeholders for future coral reef management and conservation. Data sampling employed SCUBA gear with Line Intercept Transect (LIT) at 3 M and 10 M depth. It used 30 M-transect line and each depth was laid 3 transects.Results showed that the highest number of hard coral colonies at 3 M depth was found in branching coral and the lowest in ACD, while at 10 M depth, the highest number of colonies was recorded in CMR and the lowest in ACB.  Based on percent cover, it was found that the depth of 3 M had moderate coral condition, while the depth of 10 M had poor condition. Both depths had low diversity index, high eveneness index, and low dominance index.Key words: coral reef condition,  percent cover, diversity, evenness, dominance.  ABSTRAKPenelitian ini bertujuan untuk memberikan informasi tentang kondisi terumbu karang di perairan Desa Poopoh sebagai masukan bagi pihak-pihak terkait untuk pengelolaan dan pelestarian terumbu karang di masa mendatang.Pengambilan data terumbu karang menggunakan alat SCUBA dengan metode LIT (Line Intercept Transek) pada kedalaman 3 M dan 10 M. Penelitian in menggunakan 30 M panjang  transek, dan masing-masing kedalaman ditempatkan 3 transek.Jumlah koloni karang batu terbanyak di kedalaman 3 meter ditemukan pada jenis karang bercabang (CB), 4,33 koloni dan jumlah koloni terendah pada ACD, sedangkan pada kedalaman 10 M, koloni terbanyak ditemukan CMR dan terendah pada ACB.  Berdasarkan persentase tutupan, ditemukan bahwa kedalaman 3 meter memiliki kondisi terumbu karang sedang, sedangkan kedalaman 10 M memiliki kondisi terumbu karang buruk. Kedua kedalaman memiliki indeks keanekaragaman (H’) rendah, indeks kemerataan tinggi, dan indeks dominasi tergolong rendah.Kata kunci: kondisi terumbu karang, persen tutupan, keragaman, pemerataan, dominasi.

Abstract

The aims of this study, 1). To find out the number of species and the abundance of coral fishes; 2). To find out the biomasssa of target fish in carnivorous and herbivorous groups. Data collection was carried out at 5 meters depth using the Underwater Visual Census (UVC) method. The area observation is 150 m2. Coralivorous fish are found with 8 species and are categorized as medium. 28 species of target fish were found from carnivorous fish (13 species), and herbivorous fish (15 species).  For total individual number that is 81 individuals and a density that is 3240 individuals/Ha. The highest number of individuals is found in herbivorous fish. The high value of the ecological index shows the stability of the community and the ability of the environment that allows species of fish to grow and develop in their habitat. The target fish is generally in the class size of 16-20 cm and 21-25 cm. In general, reef fish from the group of herbivores are most commonly found in this location.Keywords: Coral Fishes, Likupang Kampung Ambong ABSTRAK Tujuan penelitian, yaitu 1).
