Effectiveness of Combination of Feed Form Cake and Feed Natural Silk Worms (Tubifex Sp) on Feed Conversion Ratio (Fcr), Specific Growth Rate and Giant Freshwater Prawn Survival (Macrobacium Rosenbergii) Larval Stage

Abstract

This study aimed to determine the effectiveness of the combination of cake feed and silk worm feed on feed coneration ratio (FCR), Survival, and specific growth rate (SGR) of prawn larvae (Macrobacium rosenbergii). The research was conducted on 8 February - 9 March 2018 at the Fisheries Laboratory of University of Muhammadiyah Malang. Shrimp used in this study is larval prawns stadia larvae. This research was conducted by experimental method using randomized block design (RAL) with 5 treatments and 4 replications. P1 100% silk worm and 0% cake feed, P2 25% silk worm and 75% cake form feed, P3 50% silk worm and 50% cake form feed, P4 75% silk worm and 25% cake feed, P5 100 % feed cake form. Feed is given in ad-station for 40 days. Observed data include Feed coneration ratio (FCR), Survival, specific growth rate (SGR), and water quality. The results showed that the combination of cake feed and silk worm feed had a significant effect on the growth rate of Specific (SGR) Fcount 7.58> from F.

The Effect of Combination of Tubifex sp and Artificial Feed on the Growth and Molting of Giant Shrimp (Macrobrachium Rosenbergii) Stadia V.

“…The increase that occurs in natural feeding of silkworm and artificial feeding in cake form are appropriate combination for the giant prawns adaptation that go from natural feeding to artificial feeding, so as to accelerate the absolute growth (Sutarjo, 2018). While, cake feeding has complex value in a complete feeding ration in the nutrition content that has been determined.…”

“…It is known that the absolute and relative growth rates of giant prawns given more tubifex feeding or in P4 compared with other treatments of 101.69 mg. The high rate of growth in this 4th treatment, influenced by the complex content in the natural feeding of silkworm is needed by the giant prawns with appropriate combination and with the addition of artificial feeding in the form of cake for the giant prawns that are still in the adaptation to artificial feeding (Sutarjo, 2018). The Giant Prawns Needs of Protein is bigger than other organisms, the function of protein in the giant prawns' body, among others, to maintain the tissue, the formation of tissue, to replace the damaged tissue and growth (Yuwanta, 2010).…”
