Abstrak: Feed is one of main factor which play role to increase growth performance of eels. Besides the high feed protein (40-50%) needed from the contain of eel’s feed, source of raw material protein is determine the eel’s feed quality. The purpose of this study is to get out the best raw material of protein source for an optimal growth performance of yellow eels with moist feed. This study was performed in eight aquariums which have measurement of 90x50x40 cm3 in 120 liters/aquarium of water. Eels at yellow eel stage in 111,25 ± 0,95 gram of body weight were used. There are four treatments in this study consisted of commercial feed, feed with baby shrimp meal as main protein source, imported fish meal, and combination from local fish meal, baby shrimp meal, and imported fish. The result showed that the feed with imported fish meal is the best treatment. Survival rate of all treatments were 100% and the feed conversion rate are 3,00; 3,01; 2,96; and 3,24. There’s no significant difference in daily growth of all treatments where the value are 0,68 ± 0,18%; 0,46 ± 0,06%; 0,58 ± 0,10%, and 0,31 ± 0,07%. Protein and lipid retention rate of the best treatment are 22,30% and 603,82% respectively.

Abstrak: Eel is a commodity that high value and favored international markets, but production still can not fill market demand. The problems most often occur in the cultivation of eels is on a slow growth, high feed conversion, and low survival rates. The problems affecting the production performance is by increasing maintenance time and cost of production. Fish feed is an important factor in cultivation. Feeding with appropriate levels of protein is expected to increase growth so as to reduce production costs and improve production performance. This study uses a completely randomized design with treatments of feed that has a different protein content, i.e. 38.5%, 42.5%, and 44.5%, respectively repeated 2 times. Fish reared in concrete ponds dimensions 2 m x 2 m x 1.8 m as many as six in a pool of water flowing at the rate of 30 L/min. Eel fish used have a weight of 65.3 ± 2.73 g/fish with a density of 10 kg/m3. Feed given 4 times a day, ie at 05.00, 11:00, 16:00 and 21:00 are at satiation method. Fish maintained for 30 days with sampling every 15 days. Parameters used include survival, growth rate, diversity coefficient weights, feed conversion and water quality. The results showed differences in the protein content of the feed did not significantly affect survival, and diversity coefficient, but the real effect on the growth rate, feed intake and feed conversion. The best treatment (P<0.05) is the feed with protein content of 46.5% resulted in a 0.63% growth rate and ratio feed conversion of 2.18.
