“…It has been proven that the application of feeding strategies based on fasting (FA) and re-feeding (RF) by activating compensatory growth response (CGR) can promote the feed efficiency in different farmed aquatic species and enhance the profit margins (Ali et al, 2003;Jobling 2010). In addition, fasting can be applied for different processes in aquaculture such as control of overproduction, reduction of feed and labor expenditures, correction of errors in the feeding programs (Krogdahl and Bakke-McKellep, 2005), final production quality (Favero et al, 2020), recuperation of stress (Davis and Gaylord, 2011;Waagbø et al, 2017), overwintering of fish (Triebenbach et al, 2009), and prevention of infectious diseases (Mohapatra et al, 2017).…”

An eight-week research was carried out to examine the influence of fasting (FA) and refeeding (RF) episodes on the compensatory growth responses (CGR) in sobaity (Sparidentex hasta, 10 g) and yellowfin seabreams (Acanthopagrus latus, 4.3 g) juveniles. Fish were fed with a commercial feed (contained 500 g kg−1 crude protein and 150 g kg−1 crude lipid) as following regimes: control (C, fish were fed three times every day), T1 (two weeks of feeding, one week of FA, and five weeks of RF), T2 (one week of feeding, two weeks of FA and five weeks of RF) and T3 (three weeks of FA and five weeks of RF). Two hundred and forty S. hasta juveniles were stocked into twelve 300-L tanks (20 fish tank−1), and 360 A. latus juveniles were allocated into other 12 tanks (30 fish tank−1). Each treatment was carried out in triplicates for each species, and each tank held only one of the species. The experiment was carried out for both species simultaneously. The weight and length of fish from the four groups were measured individually after the third week (after FA episode) and after eight weeks (after RF episode). After finishing the RF episode (eighth week), six fish of each tank were sacrificed with an overdose of 2-phenoxyethanol (1000 mg L−1), and the liver and the whole gut of the sacrificed fish were sampled, dissected, and then kept in a freezer (−80 °C) until further analyses. Survival rate was decreased in S. hasta juveniles with increasing the FA period mainly due to their cannibalistic behavior, which was triggered by starvation, but it was not affected in A. latus. The fasted groups in both species were significantly lost their weight after FA episodes. After five weeks of RF, S. hasta showed full compensatory growth response; meanwhile A. latus had a partial compensatory response (P<0.05). Hepatosomatic index value decreased after the FA period in both species, but it was restored to the normal level after RF phase. The activities of liver catalase, superoxide dismutase, glutathione-S-transferase, and glutathione peroxidase were increased in T2 group in S. hasta, but liver antioxidant enzymes were not affected in A. latus. In both species, the amount of the lipid peroxidation was significantly increased in the liver of fish groups subjected to T2 or T3 compared to T1 and control groups (P < 0.05). Liver alanine aminotransferase (ALT) and alkaline phosphatase (ALP) in S. hasta fasted for two weeks were higher than the other groups. The activities of trypsin, chymotrypsin, α-amylase, and lipase in S. hasta fasted for a week (T1) were higher than control. In addition, the activities of trypsin and chymotrypsin in A. latus fasted for two or three weeks were lower than C and T1 groups. The activity of ALP was increased with increasing FA period in both species. The findings of the present study showed that single-phase FA episodes reduce survival and induce oxidative stress in S. hasta juveniles; meanwhile A. latus juveniles did not show complete compensatory growth after RF episode.

“…In the fish P. mesopotamicus, hyperphagia is observed after 6 days of refeeding but reaches its maximum after 12 days of recovery. 30 Apparent latency could be explained by the prior recovery of the digestive system, possibly affected during feed restriction, before allowing a maximum increase in feed intake. 76 Hyperphagia appears to be a short-lived phenomenon, as in the Chinese shrimp (F. chinensis), subjected to 10 days of quantitative food restriction, in which hyperphagia was observed only during the first 10 days of refeeding.…”

Compensatory growth: Fitness cost in farmed fish and crustaceans

Feed restriction in fish and crustaceans is gaining interest due to its unusual acceleration of growth after a feed deprivation period. This phenomenon, known as compensatory growth, allows deprived organisms to reach the weight of never‐stressed counterpart organisms. Since feed is the major economic and ecological burden of fish and crustaceans farming, succeeding to reduce its quantity without loss of production may enhance a sustainable aquaculture development. A wide variety of restriction/feeding protocols, involving differences in nature, duration and intensity, have been tested on aquatic organisms. However, not all of them lead to optimal compensatory growth. Furthermore, before extending this practice to industrial setting, it is essential to assess physiological costs associated with both food restriction and compensatory growth. Indeed, although fish and crustaceans appear to be tolerant to dietary restriction, it involves metabolic, digestive, oxidative and immune changes. Nevertheless, return to basal values is not always achieved through refeeding. Compensatory growth has been observed and described in many taxa; however, physiological mechanisms during this process are poorly understood. On the other hand, the acceleration of growth itself appears to generate physiological consequences in organisms, particularly through the generation of oxidative stress. This review provides an overview of the fitness consequences associated with dietary restriction and the subsequent enigmatic compensatory growth in fish and crustaceans.

“…

Feeding is basic regulatory behaviour for organisms to maintain metabolism and a steady state of energy (Duran et al, 2019). In the wild, the distribution of prey is often uneven or missing due to changes in the environment, resulting in insufficient food, which affects physiological functioning (Favero et al, 2020). The success of fish reproduction is highly dependent on food intake, food supply and feeding behaviour, which are affected by a complex set of metabolic and neuroendocrine mechanisms.

To explore the feeding regulatory mechanism of the leptin gene and its receptor, the full‐length cDNA of Tbleptin‐B and TbleptinR were cloned from Trachinotus blochii, and their expression patterns in different dietary strategies were analysed. The preprandial expressions of Tbleptin‐A, Tbleptin‐B and TbleptinR in liver showed a downward trend as a function of time. However, 1 h after postprandial, Tbleptin‐A increased significantly, Tbleptin‐B decreased significantly, TbleptinR did not change, and their postprandial expressions were not significantly different with the control group at 3 h. This result indicated that Tbleptin‐A and Tbleptin‐B were involved in the postprandial regulation of liver within 3 h. Similarly, the expressions of Tbleptin‐A, Tbleptin‐B and TbleptinR in liver were not different from the control group after refeeding (d11), which showed that the expressions of them in liver would return to normal level after long‐term hungry golden pomfret getting enough food. In hypothalamus, the postprandial expressions of Tbleptin‐B and TbleptinR were significantly increased at 1 h, while Tbleptin‐A was inhibited. Similarly, after refeeding, the expression of Tbleptin‐A was significantly lower than that of the control group, and Tbleptin‐B was significantly higher than that of the control group. In summary, Tbleptin‐A, Tbleptin‐B and TbleptinR play different roles in coping with different dietary strategies in liver and hypothalamus. Tbleptin‐A is mainly involved in dietary regulation through liver, while Tbleptin‐B and TbleptinR are mainly active in the hypothalamus. These results provide valuable information to reveal the T. blochii feeding regulatory mechanism.
