This study is done in August until October 2007 in ?SUMBER HARAPAN? farming group in kemloko village, Nglegok district of Blitar Regency and in the Fishery and Oceanography laboratory of East java province.
This study aims at finding out the influence of different fedding techniques (SGM Milk powder, duck?s yolk, and chicken?s yolk) on Koi fish (Cyprinus Carpio) aged 4 days toward the growth and its life survival of Koi fish (Cyprinus Carpio).
This study is expected to give more improvement on the life expectancy of the fish and minimize the death rate of Koi fish (Cyprinus Carpio) so that it can be used as information and consideration as well in giving the nutritious feeding to support the success of this fish seedling business.
The materials used in this study is 600 Koi fish seedlings aged 4 days weight 0.014 in each week, SGM milk powder for 0-6 months aged babies, duck?s yolk, and chicken?s yolk. The method used is experimental one and the experiment design is Complete Random sampling by giving three different treatments. Treatment A is feeding on SGM milk powder for 4-6 months aged babies, treatment B is by giving duck?s yolk, and treatment C is by giving chicken?s yolk and each treatment is repeated four times.
From the result of the study, it shows that those three different technique in feeding influence on the growth in significant way. The best result is shown by treatment A that is the giving on milk baby powder ?SGM? that is about 0.10275 gram, and it is followed by treatment B (duck?s yolk) and treatment C (chicken?s yolk) in which each is about 0.07475 gram and 0.0505 gram.
The different feeding also affects the survival rate; the best result is shown by treatment B (duck?s yolk) that is about 72.5% which is followed by treatment C (chicken?s yolk) about 69% and then it is followed by treatment A ( SGM milk powder for 0-6 months) which is about 50.5%.
Based on the measurement during the study, the water quality shows the optimum current on the temperature of 20? 26 degree Celsius (in the morning) and 24 ? 31 degree Celsius (in the afternoon); the DO (dissolved Oxygen) is about : 7.3 ? 7.5 ppm; pH (acid rate) : 7.5 -8.5 ppm.
Based on the study it is concluded that to get best growth and life survival of Koi fish seedling (Cyprinus Carpio) aged 4 days it is suggested for us to feed them with duck?s yolk.
