“…For example, significantly lower ADG (0.27-0.33 g d −1 ) has been reported in Nile tilapia (5.36 g) reared in BFT system (Hisano, Pinheiro, et al, 2021). The SGR in the present study is also much higher than that found by Elayaraja et al (2020).…”

Two freshwater macrophytes, water (Eichhornia crassipes) and coontail (Ceratophyllum demersum), were evaluated as carbon sources in biofloc system for Nile tilapia (Oreochromis niloticus), in comparison with molasses and a RAS with 10% water exchange daily (control). All-male tilapia (9.35 g) were stocked in 70-L fibreglass tanks at 10 fish tank −1 and fed on a commercial diet (30% cp) for 60 days. The average water temperature, pH and dissolved oxygen (DO) did not significantly differ (p > 0.05) among all treatments. Total ammonia-nitrogen (TAN) was significantly lower in the control group (0.11 mg L −1 ) than in biofloc treatments (0.15-0.17 mg L −1 ). Nitrite (NO 2 -N) concentrations were significantly lower, while nitrates (NO 3 -N) higher, in bioflocbased treatments (20.23-25.77 mg L −1 ) than in the control group (12.85 mg L −1 ). Biofloc volume (BFV) (28.17-33.50 ml L −1 ) and total suspended solids (TSS) (691-824 mg L −1 )were not significantly different among molasses and macrophytes treatments. The control group displayed lower growth rates and feed efficiency than macrophytesbased groups. Blood parameters, immunological responses, digestive enzymes activities, liver function enzymes and upregulation of IFNγ, TNFα and IL-8 genes were significantly better in molasses-and macrophytes-treated tanks than the control group. These results suggest that water hyacinth and coontail can be used as costless, eco-friendly carbon sources in biofloc systems.

“…Nilai efesiensi pakan diperoleh dari hasil perbandingan antara pertambahan bobot tubuh ikan dengan jumlah pakan yang dikonsumsi oleh ikan selama masa pemeliharaan. Semakin besar nilai efesiensi pakan, maka semakin efesien ikan memanfaatkan pakan yang dikonsumsi untuk pertumbuhan ikan tersebut.frekuensi pemberian makan empat kali sehari mendorong pertumbuhan terbaik dan respon efesiensi pakan pada ikan nila sebesesar 5-20 gram (Hisano, 2020).…”

Feed is the biggest component (50-70%) which causes an increase in production costs, to reduce feed production costs is to mix inexpensive and easily accessible natural feed with a high enough protein content. This study aims to determine the effect of a combination of avocado (Persea americana M.) and pumpkin (Cucurbita moschata D.) seeds on the growth of nile tilapia (Oreochromis niloticus L.). The design used non-factorial RAL consisted of 4 treatments and 6 replications, namely P0 (control feed), P1 (40 grams of avocado seed feed + 40 grams of pumpkin seeds + 20 grams of mixed material), P2 (20 grams of avocado seed feed + 60 grams of pumpkin seeds + 20 grams of mixed ingredients) and P3 (60 grams of avocado seed feed + 20 grams of pumpkin seeds + 20 grams of mixed ingredients). Data analysis using ANOVA. The results showed that feeding increased the growth of tilapia. In tilapia, a very effective growth was found in P2 feed of 16.44 grams with a growth rate of 3.12% / day. The conclusion of the study indicated that there was an effect of the combination of avocado and pumpkin seeds on the growth of tilapia.

“…The BFT also maintains its water quality at adequate levels, and can reach high productivity (30 kg/m³) and survival rates of 100% (Luo et The use of tilapia juveniles for initial stocking mainly in net cages is a growing trend in Brazil. According to Hisano et al (2020), the production of tilapia juveniles is an underexplored market and stocking at this stage has a number of advantages, such as vaccination, a reduction of the production cycle and in mortality, as well as an improvement in population homogeneity.…”

This study aimed to analyze the economic feasibility and the risk associated with the Nile tilapia juveniles cultured in a biofloc technology system. The indicators used in this study followed the operating cost criterion. Scenarios were analyzed in terms of variations in input prices and survival. Stochastic simulation were also carried out in order to determine the probabilities of economic results. The items with the greatest impact on costs were the acquisition of the greenhouse and fingerlings, which represented 27.64% (initial investment) and 33.24% (operating cost) respectively. The analysis showed that the biofloc technology system is viable in a short and long term, since it covered all the operational costs and showed a positive gross margin per production cycle, except in the pessimistic scenario. The risk analysis demonstrated that in 87.29% of the simulations obtained a positive profit. Thus, the tilapia juveniles production in biofloc technology system is a low-risk and economically viable investment.
