“…Similarly, there have been some studies in which the body chemical composition was not affected by the feeding strategies (Gaylord and Gatlin, 2000;Xie et al, 2001;Zhu et al, 2004;Turano et al, 2007). Nevertheless, the lower body lipid composition of G3 compared to the other groups in our study was caused by the reduction of lipids, which is the primary resource in fish, for the protection of basal metabolism and survival during starvation.…”

This study was designed to investigate the effects of starvation and refeeding cycles on growth performance and body chemical composition of juvenile sea bass. For this purpose, a total of 720 juveniles with an initial mean weight (IW) of 5.85±0.54 g were divided into 12 tanks (400 L) in triplicate groups. During the period of the experiment, the control group (C) was fed to satiation three times a day. The feeding regimes of the other three groups were designed as follows: 2 days starvation / 8 days satiation (G1) (5 cycles), 5 days starvation / 20 days satiation (G2) (2 cycles) and 10 days starvation / 40 days satiation (G3) (1 cycle). After 50 days, only group G1 demonstrated partial compensatory growth. The difference between the final weights (FW) of groups was found statistically significant (P<0.05). Specific growth rates (SGR) of fasting groups were lower than those of the control group (P<0.05). G1group was determined to have the best values of feed conversion ratio (FCR) and economic conversion ratio (ECR). Hepatosomatic index (HSI) did not differ significantly between groups (P>0.05). Total fat (TF) was lowest in G3 (P<0.05). The partial compensation by group G1 presents possibilities for economic optimization.

“…The PER and PR of the fish under the 6W-100 treatment was higher than those of the fish under the 8W-95 treatment, but no different from those of the fish under all other treatments in our study. Similarly, other studies showed no significant improvement in the feed efficiency although the fish achieved full compensatory growth after food deprivation (Zhu et al, 2004;Cho et al, 2006a). The CF and HSI were not affected by food deprivation or feeding ratio in this study.…”

The effects of food deprivation and feeding ratio on the growth, feed utilization and body composition of juvenile olive flounder Paralichthys olivaceus were investigated in 810 juvenile fish averaging 6.4 g in weight randomly distributed in 27 400-L flowthrough tanks. A 3 [food deprivation: 8-week feeding without food deprivation (8W), 7-week feeding after 1-week food deprivation (7W) and 6-week feeding after 2-week food deprivation (6W)] × 3 (feeding ratio: 100%, 95% and 90% of satiation, hereafter denoted by 100, 95 and 90, respectively) factorial design was applied. The weight gain of the fish was significantly affected by both food deprivation and feeding ratio. The weight gain of the fish under the 8W-100 treatment was higher than that of those under the 7W-95, 7W-90, 6W-100, 6W-95 and 6W-90 treatments, but did not differ from those of fish under the 8W-95, 8W-90 and 7W-100 treatments. The specific growth rate (SGR) and the feed intake of the fish were affected by both food deprivation and feeding ratio. However, the feed conversion ratio (FCR) was unaffected by both food deprivation and feeding ratio. The protein efficiency ratio (PER) was affected by the feeding ratio, but not by food deprivation. The protein retention (PR) was affected by food deprivation, but not by feeding ratio. Juvenile olive flounder subjected to 1-week food deprivation at 100% satiation (7W-100 treatment) achieved full compensatory growth.

“…Feeding efficiency was especially low in S4 after feeding was resumed, and did not recover until the second interval. Time may be required to reestablish effective digestive processes in the stomach following a period of feed deprivation Zhu et al, 2004).…”

We investigated compensatory growth of Nile Tilapia Oreochromis niloticus in structural size and live weight in response to different deprivation periods and refeeding. Four treatments were assigned randomly to fish in 12 glass tanks, with each treatment performed in triplicate. The control group was fed to satiation three times a day throughout the experiment. The other three treatment groups were starved for 1 week (S1), 2 weeks (S2), or 4 weeks (S4) and then fed until the end of the experiment. After the experiment, no significant differences were observed among S1, S2, and the control group in average weight or length, whereas the weight and length of S4 were significantly reduced. Relative condition factors of the three starved groups decreased significantly until the end of the restricted period but recovered rapidly after refeeding. The specific growth rate in weight (SGR W ) of the three restricted groups recovered quickly upon refeeding and were significantly higher than the control group, but these differences disappeared gradually until the end of the experiment. No significant difference in specific growth rate in length (SGR L ) was noted between the control group and the three restricted groups after refeeding. All three groups showed hyperphagia for a short period upon refeeding, and no statistical differences were observed in feeding efficiency among the four groups.
