Abstract:
The production of alternative feeds as a substitute for commercial feeds is expected to reduce the
cost of farmers, with fermentation techniques to improve feed nutrition so that it is better and more
durable by utilizing rice bran. This study aims to find out the right dose of feed and find out the effect
of feeding on the growth of koi fish seeds. The methods used are experimental and observation
techniques. Data analysis techniques use SPSS. The results of the study on fish weight produced
normally distributed data, homogeneous and there was also a real difference, namely in the
treatment A, B, C and K can be seen the best treatment, namely in B (100% fermented rice bran
feed). While the results of the study on the length of the fish produced normally distributed data,
homogeneous and there was an influence, there was also a real difference, namely the best treatment,
namely in B (100% fermented rice bran feed) with the best dose of 0.08gr. Based on the statement
above, the fermentation of rice bran affects the growth of koi fish seed cultivation.
