Abstract

The Dog conch is an important marine biota for ecology; besides that, it has economic value with high nutritional content. The purpose of this study was to analyze the density of the dog conch, to determine the appropriate environmental parameters for gonggong snails restocking, and to analyze the suitability of the location for the dog conchrestocking in Kelabat Bay, Bangka Island. This research was conducted from March to April 2021. The data collection of the dog conchand sea grasses used purposive sampling method. The highest density of the dog conchwas at station 7 with a density of 2000 (Ind/ha), while the lowest densities of the dog conchwere at stations 1, 4, 5 and 9 because dog conch was not  founded. The results of the suitability of aquatic environmental parameters are categorized as still suitable for the life of gonggong snails. The suitability index values for the location of the the dog conch restocking at stations 6, 7, 8, 9 and 10 had values above 84-89 which is categorized as very suitable, while at stations 1, 2, 3, 4, 5 with values above 75-78 were categorized as appropriate. The results of the study indicate that the waters of Kelabat Bay have certain areas that are ideal to be used as a location for the dog conch restocking, so the recommended location for Dog Conch restocking is in the outer Kelabat Bay while still paying attention to sustainable fishing efforts.  Siput Gonggong (Laevistrombus sp) merupakan hewan laut kelas gastropoda yang memiliki peran penting secara ekologis dan ekonomis. Secara ekonomi spesies ini di konsumsi dengan kandungan gizi yang tinggi sehingga sering diburu masyarakat yang berdapampak pada penurunan ukuran populasi di alam. Oleh karena itu perlu dilakukan upaya restocking untuk pemulihannya di alam. Tujuan penelitian yaitu menganalisis kepadatan siput gonggong, menganalisis parameter lingkungan, serta menganalisis kesesuaian lokasi restocking siput gonggong di Teluk Kelabat Pulau Bangka. Penelitian dilaksanakan pada bulan Maret sampai dengan April 2021. Penentuan titik lokasi penelitian menggunakan metode purposive sampling. Pengambilan data di lapangan terdiri dari kepadatan Siput Gonggong, tutupan lamun, klorofil-a, dan parameter fisika kimia perairan. Data dari lapangan dianalisis indeks kesesuaian restocking siput gonggong. Hasil penelitian kepadatan rata-rata Siput Gonggong yaitu 390 Ind/ha. Kesesuaian lokasi restocking (IKR) berkisar 75 sampai dengan 89,91 yang dikategorikan sesuai sampai dengan sangat sesuai. Lokasi yang sangat sesuai untuk restocking Siput Gonggong yaitu stasiun 6, 7, 8, 9, dan 10 dengan nilai IKR berkisar antara 84 sampai dengan 89. Sedangkan lokasi yang sesuai yaitu di stasiun 1, 2, 3, 4, dan 5 nilai IKR berkisar antara 75 sampai dengan 82. Hasil penelitian memberikan indikasi bahwa perairan Teluk Klabat terdapat wilayah-wilayah tertentu yang ideal untuk dijadikan lokasi restocking siput gonggong. Lokasi yang direkomendasikan untuk restocking Siput Gonggong terdapat pada Teluk Kelabat bagian luar.
