“…Dissolved oxygen was also reduced with an increasing density of African catfish, Clarias garienpinus [3]. Colossoma macropomum has anatomical adaptations on its lips that provide good resistance to dissolved oxygen levels between 3 and 1 mg L −1 [33][34][35][36]. The lowest oxygen levels in the present study were above 3 mg L −1 and the animals showed growth.…”

Stocking densities were evaluated for the rearing tambaqui in an RAS system. Experiment 1 used juveniles weighing 0.54 g at the following densities for 15 days: D0.3—0.3; D0.6—0.6; and D0.9—0.9 kg m−3. Experiment 2 used juveniles weighing 8.22 g at the following densities for 75 days: D0.8—0.8; D1.2—1.2; and D1.6—1.6 kg m−3. Experiment 3 used juveniles weighing 142.18 g at the following densities for 75 days: D2—2; D4—4 and D6—6 kg m−3. In Experiment 1, density did not influence performance (p > 0.05), with the exception of biomass, which was greatest in D0.9 (p < 0.05). In Experiment 2, final weight, weight gain and daily weight gain were highest for D0.8 (p < 0.05), as was triglycerides (p < 0.05), whereas biomass increased with increasing density (p < 0.05). In Experiment 3, weight, weight gain and daily weight gain were greater for D2 and D4 (p < 0.05), while final biomass was lowest for D2 (p < 0.05). Hemoglobin was lower for D4 and D6 (p < 0.05), while cholesterol and glucose levels were higher for D2 and D6 (p < 0.05). Colossoma macropomum demonstrated adaptive capacity for reared in RAS at high stocking densities.

Background Air exposure is an inevitable source of stress that leads to significant mortality in Coilia nasus. Our previous research demonstrated that adding 10‰ NaCl to aquatic water could enhance survival rates, albeit the molecular mechanisms involved in air exposure and salinity mitigation remained unclear. Conversely, salinity mitigation resulted in decreased plasma glucose levels and improved antioxidative activity. To shed light on this phenomenon, we characterized the transcriptomic changes in the C. nasus brain upon air exposure and salinity mitigation by integrated miRNA-mRNA analysis. Results The plasma glucose level was elevated during air exposure, whereas it decreased during salinity mitigation. Antioxidant activity was suppressed during air exposure, but was enhanced during salinity mitigation. A total of 629 differentially expressed miRNAs (DEMs) and 791 differentially expressed genes (DEGs) were detected during air exposure, while 429 DEMs and 1016 DEGs were identified during salinity mitigation. GO analysis revealed that the target genes of DEMs and DEGs were enriched in biological process and cellular component during air exposure and salinity mitigation. KEGG analysis revealed that the target genes of DEMs and DEGs were enriched in metabolism. Integrated analysis showed that 24 and 36 predicted miRNA-mRNA regulatory pairs participating in regulating glucose metabolism, Ca2+ transport, inflammation, and oxidative stress. Interestingly, most of these miRNAs were novel miRNAs. Conclusion In this study, substantial miRNA-mRNA regulation pairs were predicted via integrated analysis of small RNA sequencing and RNA-Seq. Based on predicted miRNA-mRNA regulation and potential function of DEGs, miRNA-mRNA regulatory network involved in glucose metabolism and Ca2+ transport, inflammation, and oxidative stress in C. nasus brain during air exposure and salinity mitigation. They regulated the increased/decreased plasma glucose and inhibited/promoted antioxidant activity during air exposure and salinity mitigation. Our findings would propose novel insights to the mechanisms underlying fish responses to air exposure and salinity mitigation.
