Abstract

ABSTRACT Bilih fishes (Mystacoleucus padangensis Bleeker) is not native species of Lake Toba, other wise it is from Lake Singkarak, West Sumatra. There  is a sharp increase in the  population number of  bilih fishes in Lake Toba  due to water quality of Lake Toba supports the  life of bilih fishes.  Therefore fishermen   of Lake Toba get benefit from the high growth of bilih fishes.  However  nowdays  the population of bilih fish in the waters of Lake Toba is almost extinct due to several reasons, including: (a) the conservation area of bilih fish has not been established and  (b) there are no regulations limiting fishing locations and fishing gear used for bilih fish species.  There are a number of strategies that have been implemented to implement efforts to preserve the bilih fish population in the waters of Lake Toba, including: (1) determination of the fishing area and conservation area for the Bilid fish; (2) population in the Lake Toba waters along with the waters that regulate it determination of the size of fish and the size of the nets that are allowed to catch bilih fish and the number of bilih fish that are allowed to be caught every day from the waters of Dabau Toba;  (3)  education of  the fishing community about the ecobiology of bilih fish;  and (4) biophysical improvement of the Lake Toba area Key wold: native species, population, bio-ecology, sustainable fisheries

Abstract

Ikan nila termasuk spesies yang  sangat mudah dibudidayakan, karena pertumbuhan dan tingkat reproduksinya lebih cepat. Pakan ikan termasuk biaya variabel terbesar untuk proses produksi, berkisar antara 60-70% dari biaya produksi. Mahalnya harga pakan ini memacu penggunaan bahan baku lokal yang bermanfaat bagi pakan ikan. Untuk menekan biaya pakan, beberapa petani ikan membuat pakan buatan dari bahan baku lokal untuk mengurangi biaya produksi. Contoh bahan pangan alternatif yang bermanfaat secara optimal adalah daun lamtoro. Tujuan dari penelitian ini untuk memanfaatkan daun lamtoro terfermentasi sebagai alternatif bahan baku lokal pakan buatan untuk meningkatkan pertumbuhan dan kelushidupan ikan nila. Penelitian ini dilakukan dari Bulan Desember 2022 hingga Februari 2023 di Laboratorium Budidaya Perairan Universitas Asahan. Metode yang digunakan adalah metode penelitian secara deskriptif dan formulasi pakan menggunakan metode segi empat pearson. Uji yang dilakukan meliputi uji fisik, uji kimia dan uji biologi dengan melihat nilai FCR, pertumbuhan berat dan panjang, kelangsungan hidup benih ikan nila, dan kualitas air. Berdasarkan uji proksimat diperoleh kandungan protein sebesar 18,73%. Kelangsungan hidup ikan nila selama pemeliharaan sebesar 100%. Pertumbuhan berat mutlak ikan nila selama pemeliharaan sebesar 4,48 gr dan pertumbuhan panjang mutlak 3,9 cm. Hasil FCR selama pemeliharaan yaitu sebesar 1,8% yang menunjukkan bahwa nilai FCR tinggi. Suhu selama pemeliharaan berkisar antara 26°C - 27,7°C dan tingkat keasaman (pH) bervariasi antara 6,3 - 7,4. Oksigen terlarut (DO) yang diukur selama penelitian memberikan hasil 5,7 - 6,6 mg/l. Kata kunci: Kualitas Air, Kelangsungan Hidup, Pertumbuhan
