Kabupaten Banyuasin merupakan salah satu wilayah perairan memiliki potensi sumberdaya perikanan dan kelautan yang besar, Salah satu usaha yang banyak dikembangkan oleh masyarakat Pesisir Banyuasin adalah usaha perikanan bagan tancap. Hasil tangkapan yang didapat setiap tahunnya terus mengalami peningkatan walau tidak dalam jumlah yang besar. Pendugaan stok ikan merupakan langkah awal dalam manajemen perikanan untuk mengetahui tingkat kepadatan stok ikan. tujuan dari penelitian ini adalah Menghitung nilai Target Strenght dan nilai densitas ikan menggunakan metode akustik di bagan tancap Perairan Banyuasin. Penelitian ini dilaksanakan pada Bulan November 2019. Survei hidroakustik menggunakan instrumen Scientific Echosounder SIMRAD EK15 single beam frekuensi 200 KHz. Pengolahan data menggunakan perangkat lunak SONAR 5, Surfer 9 dan Microsoft Excel. Hasil penelitian didapatkan 31 jenis ikan yang tertangkap selama penelitian, teri (Stoplephorus sp) dengan panjang berkisar 2.1 cm sampai 8 cm, petek (Leiognathus sp) panjang berkisar 2.5 cm sampai 10 cm dan cumi-cumi (Loligo sp) dengan panjang berkisar 0.9 cm sampai 8.1 cm, merupakan jenis ikan yang paling mendominasi berdasarkan dari hasil tangkapan per hauling. Panjang ikan yang terdeteksi berkisar 5,48 cm – 7,91 cm dengan TS berkisar antara -65.41 dB sampai -62.65 dB. Densitas ikan yang didapatkan dari akuisisi data akustik berkisar 75,89 gr/m3 sebanyak 158 ikan/1000m3 sampai 2780,96 gr/m3 sebanyak 396 ikan/1000m3. Banyuasin Regency is one of the waters that has the potential for large fisheries and marine resources. One of the many efforts developed by the Banyuasin Coastal community is the stationary lift net business. The catch that is obtained every year continues to increase, although not in large numbers. Estimating fish stocks is the first step in fisheries management to determine the density level of fish stocks. The purpose of this study is to calculate the value of target strength and density values of fish using the acoustic method in the of stationary lift net in Banyuasin waters. This research was conducted in November 2019. The hydroacoustic survey used the Scientific Echosounder SIMRAD EK15 single beam 200 KHz frequency instrument. Data processing using SONAR 5, Surfer 9 and Microsoft Excel software. The results showed 31 species of fish caught during the study, anchovy (Stoplephorus sp) with a length ranging from 2.1 cm to 8 cm, ponyfish (Leiognathus sp) a length ranging from 2.5 cm to 10 cm and squid (Loligo sp) with a length ranging from 0.9 cm. up to 8.1 cm, is the most dominating fish species based on the catch per hauling. The detected fish length ranged from 5.48 cm – 7.91 cm with TS ranging from -65.41 dB to -62.65 dB. Fish density obtained from acoustic data acquisition ranged from 75.89 gr/m3 as many as 158 fish/1000m3 to 2780.96 gr/m3 as many as 396 fish/1000m3
