Abstract
Fish feed are important factor in aquaculture. Anguilla is one of the important economic values of fishery commodity. The research purpose to find alternative protein source as raw material in fish feed. For example by fermentation of forage as “noni” leaf silage (NLS) that fermented with 0,04% marine yeast inoculant to increase the quality of silage.
Research methods is experimental with randomized block design. The treatments are different dose noni leaf silage flour. The object of research is eel with elver stadia weighing 10-20 grams with a density of 9 fish / 8000 ml. Test parameters consist of specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER).
The results of proximate analysis show feed treatments B (5% NLSF) can increase crude fat and gross energy of feed. The results of test three parameters show differences of noni leaf silage flour substitution dose in commercial feed affect the SGR, FCR and PER of Anguilla.

Introduction
Fish feed are important factor in aquaculture. Anguilla is one of the important economic values of fishery commodity both national and world wide. The research purpose to find alternative protein source as raw material in fish feed. For example by fermentation of forage as “noni” leaf silage (NLS) that fermented with 0,04% marine yeast inoculant to increase the quality of silage.
Research Methods
This study was conducted in Maret-June 2015. Research methods is experimental with randomized block design. The treatments are different dose noni leaf silage flour. The object of research is eel with elver stadia weighing 10-20 grams with a density of 9 fish / 8000 ml. Test parameters consist of specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER).
Result and Discussion
Spesific Growth Rate
On the 10th day of observation, Substitution of feed has not shown a significant affect because the eel fish are still adapting to the feed. On the 20th day, substitution of feed began to affect the SGR . Treatment A growth 0.413 % ; treatment B growth 0.721 % ; treatment C growth 0.480 % ; Treatment D grrowth 0.484 % . On the 30th day, treatment A growth 0.578 % ; treatment B growth 0.766 % ; treatment C growth 0.523 % ; Treatment D grrowth 0.074 %.
Feed Conversion Ratio
FCR average on treatment A was 2.14 ± 0.24 , treatment B was 2.44 ± 0.37 , C treatment was 2.69 ± 0.21 , treatment D was 5.39 ± 0.267
Protein Eficiency Ratio
The protein efficiency ratio on A treatment is the highest 1.18 ± 0.09. This is because the protein content in the feed A has the highest. The protein content on A treatment is 38.17 % and the fiber content the lowest is 2.26 %. The value of FCR on A treatment is the lowest of B, C, and D treatments

Conclusion
Feed treatments B (5% NLSF) can increase crude fat and gross energy of feed. The results of test three parameters show differences of noni leaf silage flour substitution dose in commercial feed affect the SGR, FCR and PER of Anguilla.
