“…In our study, feed utilisation parameters were better in the starvation groups in comparison to the control, the results suggesting that the lipid and protein in the feed were used effectively for both metabolic activities and growth in the S1 and S2 groups, but limited only to metabolic activities in group S3. These findings are similar to the results of some studies in which full or partial compensation was achieved, although different starvation and re‐feeding cycles were applied in various experiments in different fish species such as tilapia (Wang et al., ), Atlantic halibut (Heide et al., ), sea bream (Eroldoğan et al., ), olive flounder (Cho and Cho, ), Chinese sturgeon (Xiao et al., ), and rainbow trout (Azodi et al., ).…”

This study was designed to investigate the effects of starvation and re-feeding cycles on the growth performance and body chemical composition of Oncorhynchus mykiss juveniles. A total of 360 juveniles with initial mean weights (IW) of 8.46 AE 0.07 g (n = 360) were stocked into 400-L tanks in triplicate for each group, with 30 juveniles per tanks. The control group received regular feed, as is the common practice. The three other groups were periodically starved: 1 day starvation followed by 6 days re-feeding (S1), 2 days starvation followed by 5 days re-feeding (S2) and 3 days starvation followed by 4 days re-feeding (S3). The experiment lasted for 10 weeks, over the course of which the water flow rate was 4 L min À1 and the water quality parameters determined as: temperature 14.4 AE 1.1°C, oxygen 8.2 AE 0.4 mg L À1 and pH 7.5 AE 0.2. At the end of the study, S1 had the best growth performance (final weight, specific growth rate, average daily growth) of all test groups (P < 0.05). The lowest daily feed intake (DFI) and growth performance parameters were observed in S3 (P < 0.05), while protein efficiency ratio (PER), net protein utilization (NPU) and lipid efficiency ratio (LER) were higher in the S3 fish group than in the other groups (P < 0.05). Whole body protein and lipid contents were highest in S1 fish. The hepatosomatic index (HSI) and viscerosomatic index (VSI) were significantly different among groups (P < 0.05). Feed conversion ratio (FCR) was significantly lower in starvation groups S1, S2 and S3 than in the control (P < 0.05). Compensation coefficient (CC) values were higher than 1 in all starvation groups. The concluding indicate that rainbow trout exposed to 1 and 2 days of starvation in week cycles could achieve over compensation compared to the control. Additionally, partial growth compensation and improved feed utilization could be achieved in a starvation group within 3 days in a week, by beginning with the juvenile size over a 10-week experimental period.

“…Similar to our results, Blake et al (2006) reported the significantly higher whole body protein contents and lower lipid contents in rainbow trout following different restricted feeding and refeeding schedules. However, many earlier authors while studying the compensatory growth in fish due to restricted feeding and refeeding reported that at the end of the experiment there is no significant difference in whole body protein, lipid, and moisture contents between the restricted feeding groups and the continuously fed control group (Kim & Lovell 1995;Tian & Qin 2003Zhu et al 2004;Singh et al 2005;Roa & Vicente 2009;Cho et al 2010;Azodi et al 2013;Sevgili et al 2013;Srijila et al 2014). Cho et al (2010) reported that the whole body protein and moisture were not affected significantly due to restricted feeding and refeeding but the whole body lipid and ash contents were affected significantly in P. olivaceus.…”

To assess the compensatory growth, a 10‐month pond experiment was conducted in which three species of Indian major carps, viz. Catla catla, Labeo rohita and Cirrhinus mrigala (1 : 1 : 1), were stocked at 7500 ha−1 and the fish were subjected to different restricted feeding and refeeding protocols, viz. Control (C): Continuously fed for 10 months; Treatment‐1 (T‐1): Initial supplementary feeding for 2 months+ No supplementary feeding for 1 month + Refeeding for 7 months; Treatment‐2 (T‐2): Initial supplementary feeding for 2 months + No supplementary feeding for 2 months + Refeeding for 6 months; and Treatment‐3 (T‐3): Initial supplementary feeding for 2 months + No supplementary feeding for 3 months + Refeeding for 5 months in triplicate ponds. At the end of experiment, 100% growth compensation was achieved in T‐2 for all the three carp species. Among all treatments, higher weight gain, PER and PPV and lower AFCR were also recorded in T‐2, resulting in maximum fish production. The restricted feeding had significant effect (P < 0.05) on whole body chemical composition of fish. From this study, it is concluded that in 10‐month pond culture of carp in fertilized pond, the T‐2 would be the best and most economic feeding strategy.

“…Different cycles of food restriction/refeeding resulted in increased food intake during refeeding; however, only partial compensatory growth or no growth compensation was observed (Heide et al 2006;Blanquet and Oliva-Teles 2010;Türkmen et al 2011). By contrast, rainbow trout, Oncorhynchus mykiss, and black sea bream, Acanthopagrus schlegeli, both exhibited total compensatory growth when subjected to short cycles of food restriction or refeeding (Bhat et al 2011;Azodi et al 2013;Xiao et al 2013). In addition to the economic benefits of compensatory growth, the health of the fish should be taken into account following periods of reduced food because the negative energy balance can affect the immune response of the fish, making them vulnerable to pathogens (Martin et al 2010;Wendelaar Bonga 2011).…”

Feeding strategies that reduce feed and promote compensatory growth could be an interesting tool to reduce costs in the fish production. However, fish health must be monitored to evaluate if their physiological response to adverse conditions, such as parasite infection, does not become compromised. A 12-wk growth trial was conducted to determine the physiological responses of pacu, Piaractus mesopotamicus, that were subjected to different fasting/refeeding cycles and infected with the Dolops carvalhoi. The schemes were: (i) control group fish (FD), (ii) food-restricted and controlled refeeding group (FR/Rc), and (iii) food-restricted and refeeding to satiation group (FR/Rs). After 84 d, the fish were exposed to D. carvalhoi for 30 h. The fish subjected to food restriction did not exhibit compensatory growth. Cortisol levels decreased in all groups within 30 h after infection. Glucose levels increased 6 h after the D. carvalhoi in the FR/Rs and 30 h after infection in the FD. In all of the fish groups, the hematocrit values were reduced after infection, and it was associated with a reduction in the mean corpuscular volume and erythrocytes. At 30 h after infection, the number of erythroblasts increased. The use of the feeding schemes does not indicate a failure of the pacu physiological responses.
