Abstract

Taro fronds (Colocasia esculenta) are a natural ingredient that is abundantly available with sufficient nutritional content to be used as a feed ingredient. The research aims to determine the effect of fermented taro fronds (C. esculenta) on the growth and survival rate of milkfish (Chanos chanos) which was carried out at the Oesapa Pond Hatchery Unit. Milkfish (C. chanos) were distributed to experimental units according to procedures using a Completely Randomized Design (CRD) with four treatments and three replications. The treatments tested included Control (100% commercial feed), P1 (addition of 5% fermented taro fronds), P2 (8% addition of fermented taro fronds) and P3 (10% addition of fermented taro fronds). The results of the study showed that there had been an increase in absolute growth of 20.93 g, survival rate of 100% and a specific growth rate of 2.23% g/day. However, ANOVA showed that treatment had no significant effect on absolute weight, survival rate ratemand specific growth rate.

Abstract

Vannamei shrimp cultivation that applies intensive and supra-intensive technology using high stocking density treatment and maximum feeding has negative impacts such as organic waste from leftover feed and feces which causes growth in shrimp to be disrupted. This research aims to determine the effectiveness of adding EM4 probiotics to rearing media on the growth rate of vannamei shrimp. This research used a completely randomized design (CRD) with four treatments, namely without administration of probiotics, with addition of probiotics in maintenance media of 1 ml/l, 3 ml/l and 5 ml/l. The parameters measured in this research were the specific growth rate during the 28 days of rearing period. The results showed that giving probiotics at a dose of 1 ml/l gave the best specific growth rate of 3.47 g%/day on the 28th day.
