Penelitian ini bertujuan untuk mengetahui pengaruh pemberian jenis pakan alami yang berbeda terhadap laju pertumbuhan dan kelangsungan hidup larva ikan dewa (tor soro). penelitian ini menggunakan metode rancangan acak lengkap (ral) yang terdiri dari empat perlakuan yaitu perlakuan a (artemia sp. 21 hari), perlakuan b (artemia sp. 7 hari dan tubifex sp. 14 hari), perlakuan c (daphnia sp. 21 hari) dan perlakuan d (daphnia sp. 7 hari dan tubifex sp. 14 hari). tiap perlakuan terdiri dari empat ulangan, ikan yang digunakan adalah larva ikan dewa (tor soro) memiliki berat rata-rata ± 0,1 gr yang ditebar 1 ekor/liter. ikan dipelihara selama 21 hari dan diberi pakan alami (artemia sp., tubifex sp., dan daphnia sp.) juga frekuensi pemberian pakan 2 kali sehari (pagi dan sore). hasil uji anova membuktikkan bahwa pemberian jenis pakan alami yang berbeda berpengaruh nyata terhadap pertambahan panjang mutlak dan laju pertumbuhan spesifik (p0,05). nilai pertumbuhan terbaik diperoleh pada perlakuan b (artemia sp. 7 hari dan tubifex sp. 14 hari) sebesar 1,07±0,01 cm. kata kunci: pakan alami, pertumbuhan, kelangsungan hidup, ikan dewa (tor soro)

This study aims to determine the effect of feeding different types of natural feed on the growth rate and survival of larvae Dewa fish (Tor soro). This study used a Completely Randomized Design (CRD) method which consisted of four treatments namely Treatment A (Artemia sp. 21 days), Treatment B (Artemia sp. 7 days and Tubifex sp. 14 days), Treatment C (Daphnia sp. 21 days) and Treatment D (Daphnia sp. 7 days and Tubifex sp. 14 days). Each treatment consisted of four replications, the fish used are Dewa fish (Tor soro) having an average weight of ± 0,1 gr which were stocked with 1 tail/liter. Fish were kept for 21 days and given natural feed (Artemia sp., Tubifex sp., and Daphnia sp.) and frequency of feeding twice a day (morning and afternoon). The results of ANOVA test proved that the provision of different types of natural feed had a significant effect on absolute length gain and specific growth rate (P0.05). The best growth value was obtained in Treatment B (Artemia sp. 7 days and Tubifex sp. 14 days) of 1.07 ± 0.01 cm. Keywords: Natural Feed, Growth, Survival Rate, Dewa fish (Tor soro)
