The highest growth of biomass was obtained in treatment P55F3 (stocking density 55g and Frequency 1x3 days) is 185.67 g / 0.098 m2. The results of the study, indicating that the stocking density and feeding tofu with different frequenci es no significant effect (P> 0.05) on the growth of biomass, population and the growth of length silk worms. The data observed in the form of biomass growth, population, length growth and quality of water. The treatment in this treatment: P45F1: stoking density 45 g and Frequency 1x1 days, P45F2: stoking density 45 g and Frequency 1x2 days, P45F3: stoking density 45 g and Frequency 1x3 days, P55F1: stoking density 55 g and Frequency 1x1 days, P55F2 : Solid Tebar 55 g and Frequency 1x2 days, P55F3: Solid Tebar 55 g and Frequency 1x3 days, P65F1: stoking density 65 g and Frequency 1x1 days, P65F2: stoking density 65 g and Frequency 1x2 days, P65F3: stoking density 65 g and frequency 1x3 days. This research was conducted by an experimental method using a completely randomized design (CRD) factorial with 2 factors and 3 levels of treatment and repeated three times. The material used is silk worms obtained from collectors. The media used in the research is a mixture of mud, dung quail, pulp, bran, sand and EM4. This study was conducted in 26 March to located at Jln. This study aims to determine the effect of stocking density and feeding tofu to a different frequency on the growth of silk worms. auratus brooder fed with bioencapsulated Tubifex was seen compared to control group fed with depurated Tubifex.Silk worms are one type of live food favored because it has nutrients that are good for the growth of fish larvae. Likewise, a significant improvement in total wet weight gain (p<0.009), FCR (p<0.01) and SGR (p<0.04) of C. auratus fed with bioencapsulated Tubifex showed less (55%) signs of tail/fin rot. The survival was significantly higher (p<0.05) in bioencapsulated Tubifex fed group (44%) than in control (22%).
auratus fries were infected with Pseudomonas fluorescents, the bioencapsulated Tubifex fed group resisted the infection. was recorded at a level of log 5.11/g on the 90th day of experimentation. None of the bacteriological parameters of the fish gut between the experimental and control groups differed significantly (p>0.05). in Tubifex showed significant improvement in total wet weight gain (p0.05) in bioencapsulated Tubifex fed group.
