Effect of feeding a combination of silage of fish offal and fermented tofu dregs with different doses on the population and biomass of silkworms ( Tubifex tubifex)

Research output: Contribution to journalConference articlepeer-review

Abstract

Silkworm (Tubifex tubifex) is one of the natural food that is often used in fish farming. Determining the success of silkworm cultivation is strongly influenced by the culture media, which is generally rice mud. Rice field mud is a living medium for silk worms in nature, but the low nutrient content requires the addition of silage of fish offal and fermentation of tofu dregs. This study used a maintenance medium dose of 100% rice field mud (control), 75% fish offal silage + 25% tofu dregs fermentation (P1), 50% fish offal silage + 50% tofu dregs fermentation (P2), and 25% of tofu silage. fish + 75% tofu dregs fermentation (P3). The main parameters in this study were the growth of biomass and population of silkworms during 21 days of rearing. While the supporting parameters of this research are water quality parameters which include temperature, pH, and DO. Analysis of the data in this study using Analysis of Variance (ANOVA) 1 factors. The results of the calculation of optimal biomass and population were obtained in 25% silage of fish offal + 75% fermented tofu dregs with an absolute biomass value of 18.6 grams and an absolute population value of 8,698 individuals.
