“…In Phase 2, the water quality parameters of DO, temperature, pH and alkalinity for the microcosm-macrocosm system remained the same among treatments and were considered ideal for the growth of tropical species [57,71,72]. With the mature BFT system, nitrogen compounds (TAN, N-NO 2 − , and N-NO 3 − ) remained at safe levels [62], with no need for water changes, only replacement for evaporation and losses related to the clarification process (total of 1200 L), which kept SS at safe levels, especially to prevent gill occlusion and increased DO consumption by microorganisms present in the biofloc [8].…”

The objective was to evaluate the hematological and biochemical blood parameters and performance of Colossoma macropomum submitted to BFT maturation and under different feeding regimes. BFT maturation was carried out for 60 days (Phase 1). Feeding on six or seven days a week and feeding rates of 4% or 6% of biomass were tested (Phase 2). The water quality parameters were monitored throughout the experimental period. At the end of Phases 1 and 2, blood samples and zootechnical performance were evaluated. In Phase 1, total ammonia was higher on the 17th day (1.25 mg TAN L−1) and stabilized from the 21st day onwards. Nitrite reached a peak (9.67 mg L−1) on the 26th day. There was an increase in nitrate between the 25th and 60th day (1.79 ± 0.01 vs. 5.45 ± 0.01 mg N-NO3− L−1, respectively). FCR (1.90 ± 0.21), weight gain (9.81 ± 1.08 g), and SGR (1.26 ± 0.12%) were highest at 30 days of phase 1. The glucose level (118.23 ± 26.30 mg dL−1) was highest on the 30th day. The plasmatic protein (5.36 ± 0.30 g dL−1) and alanine aminotransferase (ALT) levels (27.58 ± 6.58 UI mL−1) were highest after 60 days. The hemoglobin level (5.77 ± 0.74 g dL−1) was lowest after 30 days. In Phase 2, the triglycerides, ALT, and hematocrit levels were different at the end of the experiment under all feeding regimes. Histological analysis of gills showed a normal condition for fish under BFT. It was possible to apply a feeding regime of six days a week and 4% biomass for juveniles, with 43 g on average.

“…However, previous studies on RAS have indicated that cultivating this species at stocking densities of 1.4 and 2.5 kg/m 3 does not affect performance thus studies with higher stocking densities to reach the optimal densities in RAS are warranted (Santos et al, 2021).…”

“…Tambaqui (Colossoma macropomum) (Cuvier, 1818) belonging to the family Serrasalmidae is a freshwater fish species native to the Amazon river basin and is currently the most commercially reared native species in Brazil. This species is also widely cultured in South America and certain parts of Asia (Santos et al, 2021). Traditionally, this fish species has been extensively and semi-intensively cultured in earthen ponds (de Farias Lima et al, 2019).…”

“…The authors recommended that larvae of C. macropomum can be successfully reared in slightly saline RAS at stocking densities of up to 50 larvae/L.In another study, de Souza e Silva et al (2021) found better survival, growth, and stress resistance in C. macropomum juveniles (initial weight 0.35 ± 0.10 g) at stocking densities of between 3 and 5 animals/L. However, under different experimental conditions (bigger size),Santos et al (2021) recommended 0.5 kg/m 3 ; initial weight of 34.88 ± 0.60 g and 1.5 kg/m 3 ; the initial weight of 150.61 ± 0.58 g thus indicating that optimum stocking densities correlate with the size of the stocked animals.…”

The human population is expected to reach 9.7 billion by 2050. This in turn will put more pressure on the limited available resources such as land and freshwater. Combined with the high food demand, highly virulent pathogens, and worsening effects of climate change, cases of chronic hunger and malnutrition are expected to escalate in the future. Therefore, the implementation of sustainable food production systems is crucial in safeguarding food security. Recirculating aquaculture systems (RAS) have gained much attention today for the intensive production of certain aquatic species in controlled conditions. In these systems, wastewater is purified via several water purification steps and recycled back into the system. As such, water quality parameters such as water temperature, dissolved oxygen, dissolved carbon dioxide, pH, Total Ammonia-Nitrogen, nitrites, nitrates, and total soluble solutes are maintained within the desirable range required for proper growth and survival of the reared species. However, maintenance of good water quality largely depends on certain factors, most noticeably, the stocking density. Stocking densities below and above the recommended optimal levels negatively impact the behavior, growth performance, and immunity of reared animals. As a consequence, huge production losses are incurred. This review, therefore, aims to discuss the effect of stocking density on behavior, growth performance, feed utilization, and immunity of reared species in RAS. Moreover, optimum stocking densities of several aquatic species reared in RAS under certain culturing conditions are highlighted for sustainable production of food.

“…In this context, native species with suitable productive performance tend to stand out, especially the tambaqui (Colossoma macropomum, Cuvier 1818), a native species of the Amazon River basin, currently among the most commercialized and widely spread native species in Brazilian fish farming, with remarkable productive and commercial records (Brazilian Association of Fish Farming, 2021). The production technology packages for the species are adapted to different cultivation systems, stocking densities, and varied feeding (Merola & Cantelmo, 1987;Reis et al, 2019;Santos et al, 2021).…”

New approaches to food preservation by reducing the use of synthetic compounds have highlighted active plant compounds, drawing the attention of several researchers around the world, mainly to investigate the application of these compounds in food products more susceptible to deterioration, such as seafood and freshwater fish. The objective of this article was to carry out a systematic review and bibliometric analysis to investigate trends and patterns in the literature for the topic addressed and quantitative data. The review also presents a set of relevant data on procurement, application, and trends in the investigation of bioactive compounds on shelf life extension in fish products. The review allowed us to assess that the application of active plant compounds in fish products has been more evidenced in studies from 2015. The analysis also revealed that although some species of plants and fish are recurrent in the studies, the number of coauthorships is low, demonstrating a lack of affinity between the authors of the topic. The review showed that different methods of extraction and application of plant bioactive compounds demonstrated significant effects in reducing lipid oxidation and prolonging the shelf life of fish products. However, more detailed investigations of the composition of active compounds can corroborate more promising data regarding commercial viability.
