“…Hypoxia conditions did not alter the plasma cholesterol concentrations of juvenile L. alexandri, compared to the normoxia treatment. This nding differs from other studies that found an increase or decrease in this metabolite in blood of sh also submitted to hypoxia (Bera et al 2017;Kuppitayanant et al 2011), feed restriction (Assis et al 2020;Favero et al 2019) or low water temperature (Costa et al 2016;Favero et al 2019;He et al 2015) and may be related to increased energy consumption (He et al 2015) and decreased synthesis of endogenous cholesterol by sh during stress situations. According to Costa et al (2019), exposure to stressors and the intensity of stress can lead to increased plasma protein concentrations in sh, as the energy need of these animals increases under such conditions.…”

We investigated blood gas, hematological and biochemical parameters and gill morphology and morphometry of Lophiosilurus alexandri juveniles submitted to hypoxia for 48 hours followed by recovery for 48 hours. A total of 48 juveniles (360.0 ± 141.6 g) were distributed among eight tanks (120 L) and subjected to hypoxia condition (water with dissolved oxygen at 2.12 ± 0.90 mg L − 1 ) or normoxia (at 5.60 ± 0.31 mg L − 1 ). Blood gas values (pH, PvCO 2 , PvO 2 , sO 2 , HCO 3 − , stHCO 3 − and base excess) in hypoxia were signi cantly different from normoxia, while lactate and the electrolytes (K + , Na + , Cl − , Ca 2+ and HCO 3 − ) there was no signi cant change among treatments. The erythrocytes differed signi cantly between hypoxia and normoxia at 24 h of recovery, while for hemoglobin and hematocrit there were no signi cant differences. There was a signi cant difference in glucose, triglycerides, and cholesterol for both normoxia and hypoxia, while plasma protein remained unchanged. All gill components (epithelial cells, erythrocytes, pillar cells, mucus cells, chloride cells, undifferentiated cells, and blood capillary lumen) differed signi cantly between hypoxia and normoxia. A reduction in the length of the primary lamella was observed in the hypoxia and recovery treatments, when compared to normoxia. The secondary branchial lamella showed no signi cant difference for both treatments. In general, juveniles of L. alexandri adapted well to hypoxia exposure for 48 h, as they were able to adjust most of their physiological variables to survive this stress condition and return to normoxia within 48 h.

“…Additionally, a decrease in feed intake of S. scherzeri due to either a decrease in feeding frequency or feeding ratio was also associated with a decrease in plasma TCHO concentrations [ 26 , 31 , 32 ]. In contrast, no change in TCHO concentrations was documented for pirapitinga [ 72 ], tamaqui ( Colossoma macropomum ) [ 6 ], and pacamã [ 17 ], whereas an increase was observed with pacu ( Piaractus mesopotamicus ) [ 76 ] and climbing perch ( Anabas testudineus ) [ 77 ], similarly suggesting variable results according to species and fasting regime. Therefore, further complementary research is necessary for the future.…”

“…Fish farmers employ fasting or limited feeding strategies in short- and long-term durations to reduce mortality or stress during water quality degradation, disease outbreaks, sorting, transferring, or harvesting or to simply improve feeding efficiency and reduce costs [ 1 , 2 , 3 , 4 , 5 , 6 ]. In contrast to fish fed continuously, those subjected to restricted feeding or fasting can experience greater growth once satiation feeding is resumed [ 3 , 5 , 7 , 8 ].…”

“…In contrast to fish fed continuously, those subjected to restricted feeding or fasting can experience greater growth once satiation feeding is resumed [ 3 , 5 , 7 , 8 ]. Such tendencies to return to original weights or growth trajectories are referred to as compensatory or catch-up growth [ 2 , 6 , 7 , 8 , 9 , 10 , 11 ].…”

“…Additionally, numerous studies have aimed to standardize rearing patterns through the application of limited food supply methods for reducing stress due to various unpredictable yet frequent events (e.g., environmental degradation, high/low water temperatures, disease, handling, etc. ), thereby developing appropriate feeding regimes for realistic aquaculture settings [ 5 , 6 , 13 , 14 , 15 , 16 , 17 ].…”

To verify the effect of fasting on juvenile leopard mandarin fish (Siniperca scherzeri mean weight, 14.7 g), compensatory growth, body composition, and blood content of juveniles were investigated for six weeks following two-week feeding treatments: fed continuously (control), and fasted for 5 (F5), 10 (F10) and 14 days (F14). Full compensatory growth was evident after four weeks of food resupply in all fasting groups. Specific growth rate, feeding rate, and feed efficiency in all fasting groups were significantly higher than those of the control after the first 2 weeks of food resupply. At the end of fasting, the lipid content, ratio of lipid to lean body mass, hepatosomatic and viscerosomatic indices in all fasting groups, or total cholesterol content in F14 significantly decreased compared to the control. These results indicated that juvenile leopard mandarin fish subjected to 5–14 days of food deprivation could achieve full compensatory growth after feeding resumption for 4 weeks and that the morphological and biochemical indices, as well as body and blood composition, remained comparable to the control group after the completion of the study under our experimental conditions.
