The technical viability of tilapia (I-ExCEL strain Nile or red) and giant freshwater prawn (GFP) co-culture in cages-within-tanks was evaluated while appropriate feeding protocols for tilapia-GFP co-culture in cages in a eutrophic lake were determined. Specifically, production parameters in all test species grown for five months in tank co-culture (where only tilapias were fed) were compared, while the best feeding protocol from among the following treatments: (a) Tfed—fed tilapias; (b) GFPfed—fed prawns and (c) T-GFPfed—both species fed, were defined. I-ExCEL Nile tilapias grew faster in tank co-culture whether reared singly or otherwise. However, red tilapia-GFP tank co-culture gave the best results considering key production traits in all test species (red tilapia —2.52%/day specific growth rate or SGR, 83.3% survival; GFP—1.17%/day SGR, 72.85% survival). Lake-based co-culture was technically feasible at stocking densities of 12.5/m2 for tilapia and 2.4 to 4/m2 for prawns even when only tilapias were fed; prawns grew to desired marketable sizes by thriving mainly on detritus and natural food organisms in the lake. However, further refinements can still be made to optimise the co-culture schemes to make them more sustainable and provide artisanal fish farmers options in increasing farm yields through multi-species aquaculture.

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. Table 5% (3.06) 1% (4.89), While no effect For Figures F count 0.90 <of F. Table 5% (3.06) 1% (4.89) and Feed Converation Ratio as F count 2.23 <of F. Table 5% (3.06) 1 % (4.89).
