Informasi distribusi kepadatan stok dan komposisi ikan demersal sangat penting untuk diketahui sebagai bahan masukan guna keberhasilan pengelolaan perikanan. Untuk itu dilakukan penelitian yang bertujuan untuk mengetahui komposisi, kepadatan stok dan sebaran sumber daya ikan demersal di Laut Cina Selatan. Penelitian dilaksanakan pada Mei sampai Juni 2015 dengan menggunakan scientific echosounder BIOSONICS DT-X dan frekuensi 120 KHz. Untuk verifikasi data akustik terutama komposisi jenis dilakukan pengoperasian trawl. Hasil penelitian menunjukkan komposisi jenis ikan demersal di Laut Cina Selatan meliputi 147 spesies dari 55 famili. Stratifikasi komposisi dikedalaman 20-30 m, 30-40 m, 40-50 m, 50-60 m, dan 60-70 m masing masing didominasi oleh ikan dari famili Leiognathidae, Lutjanidae, Nemipteridae, Tetraodontidae, dan Serranidae. Estimasi kepadatan stok sumber daya ikan demersal di Laut Cina Selatan berkisar antara 0,16 – 2,85 ton/km2 dengan rata-rata kepadatan 1,05 ton/km2. Information about density distribution and composition of demersal fish stocks is very important to be known as an input for the success of fisheries management. Current research aimed to determine the composition, stock density and distribution of demersal fish resources in the South China Sea. The research was conducted in May to June 2015 using scientific echosounder BIOSONICS DT-X and frequency of 120 KHz. Trawler sampling was done to verify the acoustic data, especially for species composition. The results show that the species composition of demersal fish in the South China Sea consisted of 147 species of 55 families. The stratification of the composition at the respective depth of 20-30 m, 30-40 m, 40-50 m, 50-60 m and 60-70 m, were dominated by fish families of Leiognathidae, Lutjanidae, Nemipteridae, Tetraodontidae, and Serranidae. The estimated stock density of demersal fish resources in the South China Sea ranged from 0.16 to 2.85 tonnes/km2 with the average of 1.05 tonnes / km2.
