Abstract

Ikan opudi, Telmatherina bonti, termasuk ikan endemik di Danau Towuti. Ikan opudi sudah menurun populasinya, sehingga perlu dilestarikan dengan domestikasi. Tujuan penelitian adalah untuk mengevaluasi pengaruh pemberian pakan alami yang berbeda terhadap kelangsungan hidup, pertumbuhan dan kandungan proksimat tubuh ikan opudi dengan masa pemeliharaan selama 60 hari.  Penelitian ini menggunakan rancangan acak lengkap dengan tiga perlakuan, yaitu pemberian Daphnia sp., Artemia salina dan  Chironomus sp dengan 3 kali ulangan. Sintasan dan pertumbuhan mutlak dan kandungan protein tubuh ikan yang tertinggi diperoleh pada pemberian Chironomus sp. Sintasan, pertumbuhan berat mutlak, pertumbuhan panjang mutlak, dan kandungan protein tubuh ikan yang diperoleh berturut-turut adalah 83,33±6,67%, 3,53±0,36 g, 4,98±0,50 cm, dan 64,85%. Kualitas air selama pemeliharaan adalah sebagai berikut suhu 27,2 - 28,60C, pH 7,4 - 8,3, oksigen terlarut 6,0 -  8,7 mg/l dan amoniak 0,044 - 0,074 mg/l. Ikan opudi sudah dapat dipelihara secara ex-situ.Opudi fish, Telmatherina bonti is an endemic fish in Lake Towuti. Opudi fish population has decreased, so it needs to be preserved through domestication. The aim of the study was to analyze the effect of different natural feeds on survival, growth and proximate body content of opudi fish during 60 days of rearing. The study was used a completely randomized design with the treatment of Daphnia sp, Artemia salina and Chironomus sp with 3 replications. The highest natural food for survival and absolute growth as well as protein content of fish body was Chironomus sp. The survival, absolute weight growth, absolute length growth, and body protein content of fish obtained were 83.33 ± 6.67 %, 3.53 ± 0.36 g, 4.98 ± 0.50 cm, and 64 .85%, respectively. Water quality during maintenance was as follows: temperature 27.2 - 28.60C, pH 7.4 - 8.3, dissolved oxygen 6.0 - 8.7 mg/l and ammonia 0.044 - 0.074 mg/l. Opudi fish was reared ex-situ.
