Abstract

This study was aimed to determine the effect of fish oil addition on growth performance and fatty acid compositionof eel Anguilla bicolor bicolor. Freswater eel at an initial body weight of 9.90± 0.05 g were maintained in aquariumwith volume of 120 L at stocking density of 1 g/L for 40 days. This research applied complete randomized designwith four treatments addition of fish oil, i.e. 0%, 5%, 10%, and 15%. All treatments were carried out in triplicate.Feed given as much as 3% of the fish biomass a day for four times at 06:00, 11:00, 16:00 and 21:00. The resultsshowed that the addition of fish oil in the diet have different effects (p<0.05) on specific growth (0.88–1.36%), feedefficiency (30.18–48,53%), protein retention (14. 57–20.24%), fat retention (16.77–52.49%), energy retention(12.38–20.20%), and hepatosomatic index (1.72–2.72%) whereas the survival showed no difference (p>0.05) at100%. In the fatty acid composition total of unsaturated fatty acid composition was 30.91–40.95%, n-3 fattyacids was 6.10–8.19%, and n-6 fatty acids were 6.18–8.19%.

Abstract

Abstract. The feed is one of the components that support the growth and survival in fish culture. One of the alternative feed ingredients which could use as other feed ingredient was Indigofera zollingeriana leaves. The aims of this research was to determine the use of Indigofera zollingeriana leaves on the growth performance of Patin (Pangasius sp.). This research consisted of five treatments and three replications. Indigofera zollingeriana leaves were used in the diet amount of P0 (0%) (without Indigofera zollingeriana leaves addition ), P1 (10% Indigofera zollingeriana leaves addition), P2 (20% Indigofera zollingeriana leaves addition), P3 (30% Indigofera zollingeriana leaves addition), and P4 (40% Indigofera zollingeriana leaves addition). The result showed that the use of Indigofera zollingeriana leaves had a significant effect on the fish growth performance. The use of 20% zollingeriana Indigofera produced the best results of the absolute weight of 2.15 g, 1.00% daily growth rate and feed efficiency of 44.60%.Keywords: Patin, feed ingredient, Indigofera zollingeriana leaveAbstrak. Pakan merupakan komponen yang menunjang pertumbuhan dan kelangsungan hidup dalam budidaya ikan. Salah satu bahan baku alternatif yang dapat digunakan sebagai bahan pakan ikan yaitu daun Indigofera zollingeriana. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan daun Indigofera zollingeriana terhadap kinerja pertumbuhan pada ikan patin. Penelitian ini terdiri dari lima perlakuan dan tiga ulangan. Perlakuan penggunaan daun Indigofera zollingeriana terdiri dari P0(0%) (tanpa penambahan daun Indigofera zollingeriana), P1 (penambahan daun Indigofera zollingeriana 10%), P2 (penambahan daun Indigofera zollingeriana 20%), P3 (penambahan daun Indigofera zollingeriana 30%), dan P4 (penambahan daun Indigofera zollingeriana 40%). Hasil penelitian menunjukkan bahwa penambahan daun Indigofera zollingeriana menunjukkan kinerja pertumbuhan pada ikan patin. Penambahan Indigofera zollingeriana sebanyak 20% menghasilkan hasil terbaik yaitu pertumbuhan bobot mutlak sebesar 2,15 g, laju pertumbuhan harian 1,00% serta efisiensi pakan sebesar 44,60%.Kata Kunci: Bahan pakan, daun Indigofera zollingeriana, ikan patin
