Perairan danau dan sungai Poso sudah lama diketahui sebagai daerah penangkapan ikan sidat. Ikan sidat termasuk famili Anguillidae merupakan ikan katadromus yaitu ikan yang hidup di perairan tawar (sungai/danau), bermigrasi ke laut untuk melakukan pemijahan dan setelah itu kembali lagi ke perairan tawar untuk melanjutkan siklus hidupnya. Benih ( glass eel/elver) sidat di aliran Sungai Poso sendiri bergerak dari Muara Poso, kemudian bermigrasi anadromus untuk sampai ke perairan tawar melewati beberapa wilayah sungai seperti Sungai Pandiri, Sulewana menuju Rawa Tentena dan kemudian berakhir di Danau Poso. Tujuan dari penelitian ini adalah untuk mengetahui karakteristik perairan yang dilalui fase-fase ikan sidat. Penelitian karakteristik perairan ikan sidat telah dilakukan pada bulan Maret, Mei, Juli dan September 2012 dengan metode survei berstrata. Dari pengamatan diperoleh hasil bahwa karakteristik dari lima stasiun pengamatan hampir sama, dimana karakteristik dasar perairannya berbatu dan berpasir, vegetasi yang tumbuh di sekitar sungai juga sama seperti pohon-pohon besar dan alang-alang. Kondisi kualitas perairan di aliran Sungai Poso yang dilewati oleh fase-fase ikan sidat juga masih mendukung untuk kehidupan sidat.

Sidat (Anguilla spp.) merupakan ikan konsumsi yang memiliki nilai ekonomis penting, baik untuk pasar lokal maupun luar negeri. Teluk Pelabuhanratu merupakan daerah dengan potensi besar bagi penyediaan benih ikan sidat. Salah satu faktor penting yang mempengaruhi kehidupan ikan sidat adalah salinitas, karena secara alami ikan sidat bermigrasi dari perairan tawar, payau, dan laut atau sebaliknya. Sehingga diperlukan cara untuk menggambarkan persebaran larva ikan sidat (impun) berdasarkan salinitas. Untuk mengetahui nilai salinitas diperoleh dari citra Landsat 8 tahun 2015 dan 2016 menggunakan pendugaan salinitas Algoritma Cimandiri (Supriatna et al., 2016). Penelitian dilakukan di muara Ci Mandiri, Ci Tepus dan Ci Maja berdasarkan bulan basah dan bulan kering. Keberadaan larva ikan sidat (impun) yang diperoleh dari hasil tangkapan terjadi saat bulan kering dimana hasil tangkapan terbanyak terjadi di mulut muara. Hasil tangkapan berkurang jika semakin jauh dari mulut muara, yaitu pada bagian pantai ke arah laut dan bagian dalam muara sungai dengan nilai salinitas ke arah laut meningkat sedangkan nilai salinitas ke arah sungai berkurang. ...... Eel (Anguilla spp.) is consumed fish that has an important economic value, either for local or international market. Pelabuhanratu Bay is an area with big potension for supplying eel seed. One of important factor which affect an eel existence is salinity, because eel migrate from fresh water, brakish, and sea naturally although the otherwise so that need ways to describe the distribution of glass eel by the salinity. To find out the percentage of salinity, it obtained from Landsat 8 Imagery year 2015 and 2016 using salinity prediction of Algorithm Cimandiri (Supriatna et al., 2016). The research has been conducted at Ci Mandiri Estuary, Ci Tepus Estuary, and Ci Maja Estuary based on wet month and dry month. The existence of glass eel which is obtained from the catch was occurs on dry month when the most catch was occurs at the edge of estuary. The catch is reduced if it?s farther from the edge of estuary, at the beach towards the sea and the inside of river estuary with the percentage of salinity towards the sea is increase while the percentage of salinity towards the river is decrease.

Ikan sidat (Anguilla spp.) merupakan ikan bernilai ekonomis penting. Beberapa Negara seperti Jepang, Korea dan Negara-negara di Eropa merupakan pangsa pasar ikan sidat yang potensial. Penyebaran ikan ini di Indonesia sangat luas, salah satunya perairan Danau Poso Sulawesi Tengah. Stok ikan sidat memiliki keterbatasan karena belum dapat dikembangbiakkan dengan sistem budidaya, sehingga ketersediaannya sangat tergantung dari alam. Sampai saat ini aktivitas perikanan terhadap ikan sidat adalah kegiatan pembesaran sampai ukuran bernilai ekonomis. Penelitian dilakukan dari Mei-September 2012 di Pusat Penelitian Limnologi LIPI. Tujuan penelitian untuk mengetahui kondisi kualitas air pada sistem pemeliharaan yang sesuai untuk pembesaran larva ikan sidat. Pembesaran larva sidat menggunakan dua sistem pemeliharaan, yaitu sistem bak air diam (kubus) dan bak air mengalir ( raceway) dengan tiga ulangan. Hasil penelitian menunjukkan bahwa parameter konduktivitas (p=0,047), Nitrit (p=0,004), Suhu (p=0,046), Pospat (p=0,049) serta Total Pospat (p=0,032) menunjukkan perbedaan nyata pada dua sistem pemeliharaan tersebut. Hasil analisis PCA menunjukkan pertumbuhan berat (W) dan panjang (L) larva sidat dipengaruhi oleh konsentrasi DO, Suhu, TP, PO4 dan NH4. Rata-rata pertumbuhan panjang larva sidat pada bak air diam 65,59 % (3,19 cm) sedangkan pada bak air mengalir 65,92 % (3,25 cm). Rata-rata pertumbuhan berat larva sidat pada bak air diam 384,49 % (0,756 gr), sedangkan pada bak air mengalir 412,72 % (0,796 gr). Hasil ini menunjukkan bahwa bak uji air mengalir lebih baik untuk pemeliharaan atau pembesaran larva ikan sidat.
