Abstract Introduction More eco-friendly aquaculture technology is required to reduce environmental pollution which has become a major issue in aquaculture industries in the last few decades. Aquaponics system is a culture technology to solve this waste issue. Thus, this study aimed at comparing growth performances, feed utilization efficiency, and nutrient recovery in aquaponics and conventional aquaculture system. Materials and methods Twenty-four juveniles of Nile tilapia (Oreochromis niloticus) weighing 1.12 ± 0.1 g were cultured in either aquaponics systems or conventional aquaculture systems for 30 days. Each system had three culture systems as replicates. The fish were fed the same amount with a commercial pellet three times a day. Results The result showed that the Nile tilapia reared in the aquaponics system had a significantly higher specific growth rate than that of fish reared in the conventional system, 7.5 and 6.3% BW/day, respectively. Similarly, the feed utilization efficiency of fish reared in the aquaponics was also significantly better than that of fish in the conventional system. Furthermore, the total biomass harvested from the aquaponics system was nearly eight times higher than the total biomass harvested from the conventional system. Conclusion Growth, feed utilization efficiency, and total nutrient recovery in terms of biomass were higher in the aquaponics system. These results suggest that aquaponics is not only an eco-friendly aquaculture system, but also could produce more biomass than a conventional aquaculture system, and therefore, could be scaled up in a commercial scale.

Feed Utilization Efficiency

Feed utilization by tilapia (Oreochromis niloticus) was less optimal. Feed utilization efficiency (FUE) by tilapia could be improved by feed them with the suitable E/P ratio value of feed. This studi was aimed to examine the effect of various dietary protein with the E/P ratio of 8,5 kcal/g protein on the growth of nile tilapia. The experimental fish used was nile tilapia with the average body weight of 0,50±0,02 g/fish. The feed was given three times a day i.e. at 8.00 am, 12.00, and 4.00, pm by applied at satiation method. The experimental fish was maintained for 35 days with the density of 1 fish/l. The experiment used was completely randomized design with 4 treatments and 3 replicates. The treatments A, B, C, and D were trial feeds with protein content of 28, 30, 33, and 36% with DE content 240, 255, 280.5, and 306 kcal, respectively. The variables measured were total feed consumption (TFC), ratio efficiency protein (REP), specific growth rate (SGR), and survival rate (SR). The data showed that various dietary protein with equal E/P ratio resulted significantly effect (P<0,05) on FUE, REP, and SGR; but did not significantly effect (P>0,05) on TFC and SR. The TFC values of A, B, C, and D were 17,84±1,24, 18,70±0,28, 17,42±0,53, and 18,65±0,34 g; FUE values were 27,20±2,49, 38,19±3,84, 41,05±1,74, and 44,49±5,60%; REP values were 0,96±0,09, 1,28±0,13, 1,26±0,05, and 1,25±0,16%; and SGR values were 1,46±0,08, 1,94±0,28, 1,95±0,08, and 2,05±0,30%/day. The SR values of A, B, C and D were 100±0,00, 97,78±3,85, 97,78±3,85, and 95,33±4,04%, respectively. It was suggested that the increase of dietary energy and protein with a certain level of E/P ratio could improve the feed utilization efficiency and growth of tilapia

High protein content in maggot is one of the advantages for increasing fish growth through artificial feed. This study aimed to find the best optimization and feed formulation for fish meal substitution with maggot meal on growth, feed utilization efficiency, and survival rate of milkfish (C. chanos). Milkfish (C. chanos) with an average weight of 0.62±0.01 gram/fish was used as test fish. Feeding is carried out at 07.00 a.m., 12.00 p.m., and 17:00 p.m. through fixed feeding rate method. The tested fish was kept for 42 days with a stocking density of 1 fish/l. The experimental design used was a completely randomized design with five treatments and three replications. The treatments which had been done were fish meal substitution with maggot meal as follows: A (0%), B (25%), C (50%), D (75%), and E (100%). The research parameters included total feed consumption (TFC), feed utilization efficiency (FUE), protein efficiency ratio (PER), relative growth rate (RGR), survival rate (SR), and water quality. The results showed that the fish meal substitution with maggot meal had a significant effect (p<0.05) on FUE, PER, RGR and had no significant effect (p>0.05) on TFC and SR. The best treatment of each treatment is in treatment C with a composition of 50% maggot meal substitution on fish meal which resulted in a TFC value of 40.17±4.58, FUE of 27.51±0.77, PER of 0.83±0.03%, and RGR of 2.34±0.10.

Chitosan is a functional polysaccharide that is capable of inducing various biological activities. This research aims to examine the effect of chitosan on growth and blood profile of tilapia fish. The method used in this research was experimental methods with completely randomized design (RAL) consisting of 4 treatments and 3 times. 120 Tilapia fish in 5-7 cm in range size were reared in aquarium at density of 10 fish/aquarium. Feedwere given at the additional dose of 10 ppt, 50 ppt, and 100 ppt chitosan. The observed variables were growth rate, survival rate, fish blood profile, water quality, feed utilization efficien . The results showed that the best chitosan treatment was at a dose of 100 ppt which produced FCR of 3.48 ± 2.25, AGP: 0.13 ± 0.03, SGR: 0.85 ± 0.84 and EPP: 28.70 ± 16,54.
