“…Tambaqui is being reared in different systems, such as in earthen ponds with minimal water exchange and under aeration regimes (emergency and supplementary) at 12.5 fish/m 2 (Izel‐Silva et al, 2020), incages at densities of 300–480 fish/m 3 (Frisso et al 2020) and also in BFT testing the efficacy of Bacillus subtilis at 100 fish/m 3 (dos Santos et al 2020), indicating the species capacity to adapt to different systems. Silva and Fujimoto (2015) also reported this species capacity to tolerate high density, but optimal stocking density in BFT systems is still not well established.…”

Biofloc systems (BFT) are considered environmentally friendly as they operate with minimal water use, which is enhanced by the performance of specific microbial communities effective in controlling nitrogen by-products that are potentially toxic to animals (Avnimelech, 1999). Currently, production technologies in BFT have been made available mainly for shrimp (Litopenaeus vannamei) (Ferreira et al. 2020) and Nile tilapia (Oreochromis niloticus) (Cao et al., 2020).Despite prospects for the viability to produce tilapia in BFT, legal restrictions in regions like the Amazon restrain the expansion of aquaculture activity with ruling aspects related to deforestation and, consequently, occupation of areas and use of water resources, in addition to culturing non-native species (Benatti & Fischer, 2018;Junk, 1984). In line with this, BFT can be considered a strategy to extend aquaculture. However, in order to be economically feasible, production intensification is frequently required as well as the target organism to tolerate higher densities (Krummenauer et al., 2011). Thus, the knowledge on the response of the most important species in the Amazon, such as the tambaqui (Colossoma macropomum) in BFT systems, can contribute to develop aquaculture in the tropical region worldwide.

“…Water quality parameters remained within the recommended range for neotropical sh species (Baldisserotto 2020), except for dissolved oxygen, which was below 4 mg L − 1 . Low levels of dissolved oxygen were also observed in the morning in other studies in ponds with tambaqui in the Amazon region (Gomes and Silva 2009;Izel-Silva et al 2020) and in cages in oodplain lakes (Chagas et al 2005(Chagas et al , 2007, as well as with tambatinga ( Colossoma macropomum x Piaractus brachypomus) reared in seasonal ponds during the wet season (Lima et al 2018). Low oxygen levels (< 1 mg L − 1 ) are common in the natural habitat of tambaqui, and the species developed some physiological adaptations that allow survival and growth in such conditions (Chagas et al 2007;Neves et al 2020).…”

Two feeding rates, 3% and 4% body weight per day (3%BW and 4%BW), and two feeding frequencies, twice and three times a day, were assessed during 84 days at the initial grow-out phase of tambaqui in earthen ponds. In a completely randomized 2x2 factorial experimental design in quadruplicates, 4,800 juvenile tambaqui (94.5 ± 6.4 g) were assigned to sixteen 300-m2 earthen ponds. No mortalities or difference in growth between treatments were observed during the trial. Total feed intake and feed conversion ratio were low in the fish fed at 3%BW. Fat deposition in the fish carcass and concentration of glycogen and lipid vacuoles in the hepatocytes were also low in fish fed at 3%BW. Plasma cholesterol and triglycerides were higher in the fish fed three times a day at 4%BW. Increased concentration of malonaldehyde was observed in the carcass of fish fed three times a day at 4%BW at the end of the storage period. Fish fed twice a day presented higher total feed intake per meal than fish fed three times a day, demonstrating that tambaqui was able to regulate the feed intake to benefit from a low feeding frequency. No difference was observed in pond phytoplankton and zooplankton concentration or sediment chemistry. Fish fed at 3%BW presented higher stomach content weight, demonstrating the contribution of the natural food as a complementary nutrition to tambaqui. Based on the results, tambaqui of 95 to 350 g reared in earthen ponds may be fed twice a day at 3%BW.

“…Aquaculture used automatic aerator systems that monitored DO level fluctuations, resulting in lower energy costs [12]; [19]. The method restricted the excessive supply of DO, which is provided by mechanical aerators.…”

“…Therefore, considerable work should go into creating better operational plans for aerators [11]. Regarding aeration management, J. Izel-Silva [12] investigated feasibility of using two aeration strategies in the Tambaqui production. They proposed that an emergency aeration regime (at DO<3 mgL−1) preferable to supplementary aeration in terms of growth performance, economic efficiency, and fish health maintenance.…”

Aeration plays a pivotal role in an intensive shrimp pond regarding shrimp growth and energy costs. The purpose of this study was to find a way to reduce energy costs while maintaining shrimp performance. The study was carried out in about 0.3 hectares of outdoor ponds for 80 days with stocking density being set to 80 shrimp/m2 in two types of treatment an Automatic (AP) and a Manual paddlewheel (MP). Parameters observed were dissolved oxygen (DO) concentration, temperature of water and pH, energy cost, and shrimp biomass. Resulting study found that mean DO concentrations in both treatments were not significantly different, which were 4.99 ± 1.45 ppm and 4.94 ± 1.54 ppm for AP and MP respectively. Temperature and pH were also found to be in same range of 26.81-34.08 oC and 7.8-8.3. Differences in paddlewheels had no effect on final biomass; AP produced 2249.56 ± 300.67 kg, while MP resulted in 1547.43 ± 359.04 kg. However, the treatments reduced total energy costs significantly, from $657.84 ± 6.13 for MP to $409.76 ± 3.52 for AP. Using of an automated paddlewheel based on real-time DO concentration can contribute significantly to lowering production costs and energy consumption without interfering with shrimp performance.
