“…Similar findings on full compensation have also been reported in sparid species by Silva et al (2019) in juvenile Lophiosilurus alexandri, a carnivorous Neotropical catfish; Jafari, Falahatkar, and Sajjadi (2018) in Siberian sturgeon; and Rueda, Martinez, Zamora, Kentouri, and Divanach (1998) in red seabream, Pagrus pagrus deprived for 7, 14 or 28 days and followed by 91 days of re-feeding.…”

“…A similar result was observed by Morshedi et al () for Siberian sturgeon, Acipenser baerii in the same protocol. Similar findings on full compensation have also been reported in sparid species by Silva et al () in juvenile Lophiosilurus alexandri , a carnivorous Neotropical catfish; Jafari, Falahatkar, and Sajjadi () in Siberian sturgeon; and Rueda, Martinez, Zamora, Kentouri, and Divanach () in red seabream, Pagrus pagrus deprived for 7, 14 or 28 days and followed by 91 days of re‐feeding. In addition, Bavcevic, Klanjscek, Karamarko, Anicic, and Legovic () reported full compensation in gilthead seabream, Sparus aurata with feeding limited at 1.4% body weight for 30 days followed by re‐feeding to satiation for 30 days.…”

An 80‐day feeding trial was conducted to evaluate the influence of different short‐term fasting and re‐feeding strategies on growth and physiological responses in yellowfin seabream, Acanthopagrus latus (2.4 ± 0.2 g) fingerlings. The fish were subjected to four different feeding regimes, and the control group fed four times daily to apparent satiation throughout the whole feeding period, while the other three groups were deprived for 2, 4 and 8 days followed by 8, 16 or 32 days of re‐feeding (F2R8, F4R16 and F8R32, respectively) in repeated cycles for 80 days. The fish in the control and F2R8 groups had the highest and the lowest total length, respectively (p < .05). Moreover, fish exposed to F4R16 had the highest hepatosomatic indices, while control fish had the lowest hepatosomatic indices (p < .05). Fish in the F2R8 group relatively had higher catalase and glutathione‐S‐transferase activities than other groups (p < .05). Furthermore, total protease, α‐amylase and alkaline phosphatase activities in the F4R16 and F8R32 were higher than the F2R4 and control groups (p < .05). Overall, this study showed that compensatory growth in weight and length and digestive enzyme activities were observed in the F4R16 and F8R32; however, the increase in the activity of antioxidant enzymes in the F8R32 group indicated that oxidative stress remained after 80 days of re‐feeding in the liver.

“…To date, two major restrictive feeding strategies were widely used, including short-term fasting, refeeding, and protein-restricted feeding. Short-term fasting and refeeding can produce the compensatory growth phenomenon that has been reported in Lophiosilurus alexandri ( Silva et al, 2019 ), Barbonymus schwanenfeldii ( Eslamloo et al, 2012 ), Acipenser baerii ( Morshedi et al, 2013 ), Fenneropenaeus chinensis ( Zhang et al, 2010 ), Cherax quadricarinatus ( Stumpf et al, 2011 , 2014 ), and Penaeus vannamei ( Shao et al, 2020 ). However, the unsatisfactory performance of short-term fasting and refeeding has also been reported widely: fish subjected to short-term fasting and refeeding were unable to maintain the same growth rate as control fish ( Eroldoğan et al, 2008 ; Peres et al, 2011 ; Takahashi et al, 2011 ).…”

A 6-week feeding strategy experiment was conducted to investigate the effects of time-dependent protein restriction and subsequent recovery on shrimp. Diets with protein levels of 43 and 36% were used as adequate and restricted diets, respectively. Shrimp with an initial body weight of 6.52 ± 0.46 g were given four feeding strategies: feeding on an adequate diet for six weeks (T1, the control), having protein-restricted diet in weeks 1 and 4 (T2), being given a protein-restricted diet in weeks 1, 3, and 5 (T3), and having protein-restricted diet in weeks 1, 2, 4, and 5 (T4). WG, SGR, FE, and PER of shrimp in T1–T3 showed no significant difference (P > 0.05), these indicators of T4 were significantly reduced (P < 0.05). No significant differences were found in digestive enzyme activities of shrimp among all treatments (P > 0.05). Crude protein content of shrimp muscle in T4 was lower than that of T1–T3. The expression level of tor in T4 was lower than that in other treatments, while 4e-bp was higher than that of other treatments. To balance saving on feeding cost and growth performance, giving the shrimp a protein-restricted diet for 1 week with subsequent refeeding (T2 and T3) is suitable for shrimp under high-density conditions.

“…Ministério do Meio Ambiente, 2014; ICMBio, 2016). A series of studies has been conducted with the aim of expanding knowledge regarding reproduction, physiology and growth of the species (Costa et al, 2015; Silva et al, 2019; Takata et al, 2018). Moreover, the species has potential for aquaculture because of the quality of its flesh (Sant'ana et al, 2014) and its ability to be conditioned to accept formulated diets via different methods of feed‐conditioning (Cordeiro et al, 2016; Luz et al, 2011), which has facilitated studies of nutrition and large scale production for the species (Melo et al, 2016; Santos et al, 2012).…”

The present study investigated the effects of salinity on growth, mortality, gill morphology and muscle cellularity in Lophiosilurus alexandri. Fish were submitted to the following salinity for 28 days: 0 (S0), 2.5 (S2.5), 5.0 (S5), 7.5 (S7.7) and 10 (S10) ppt. Growth and protein efficiency ratio (PER) decreased with the increase of salinity. All fish from S10 died between the 16th and 21st day of the experiment. Mortality in S7.5 was 78% at the end of 28 days of salinity exposure. Increased salinity was accompanied by increased vascular congestion, hyperplasia of gill filament epithelium, lamellar fusion and loss of structural integrity of pillar cells. Fish at S2.5 and S5 had higher mucosal cell hyperplasia. Chloride cell quantity was higher in fish in the S2.5 to S7.5. In general, L. alexandri juvenile exposed to treatments of freshwater and S2.5 had similar patterns of muscle cellularity, with high averages for the most of the variables of muscle cellularity evaluated. The large fibre size classes tended to decrease with increasing salinity. L. alexandri juveniles may be cultivated up to 2.5 g of salt/L, and superior concentrations change growth, induce damage to gills and modify muscle cellularity.
