“…The possibility of full compensatory growth of fish varies depending on fish species, fish size, feeding protocol, water temperature, feed nutrients, duration of feeding trial, etc. (Bilton and Robins 1973; Jobling and Koskela 1996; Rueda et al 1998; Gaylord and Gatlin 2000, 2001; Wang et al 2000; Tian and Qin 2004; Cho 2005a, 2005b; Cho and Jo 2005). However, weight gain of flounder in the 2WS + 6WF treatment was significantly ( P < 0.05) higher than that of fish in the (5DS + 9DF) × 4 and (4DS + 10DF + 6DS + 8DF) × 2 treatments, but not significantly ( P > 0.05) different from that of fish in the (1WS + 3WF) × 2, (10DS + 18DF) × 2 and (2DS + 5DF + 3DS + 4DF) × 4 treatments.…”

“…Compensatory growth of fish, which is rapid or faster than normal growth rate of fish, resulting from refeeding after undernutrition could be an applicably effective fish culture technique in the occurrence of red tide and cold‐water mass (Cho et al 2006). Compensatory growth of fish was largely influenced by several factors, such as fish size or age (Bilton and Robins 1973), feeding protocol (Jobling and Koskela 1996; Rueda et al 1998; Gaylord and Gatlin 2000), nutrient levels in the diet (Gaylord and Gatlin 2001), feeding regimes (Wang et al 2000; Cho and Lee 2002; Tian and Qin 2003, 2004; Cho 2005a, 2005b; Cho and Jo 2005; Cho et al 2006; Oh et al 2007), and so on. Also compensatory growth has been observed in most of the cold‐, warm‐, and tropical‐water finfish species (Bilton and Robins 1973; Quinton and Blake 1990; Damsgaard and Dill 1998; Rueda et al 1998; Gaylord and Gatlin 2000, 2001; Wang et al 2000; Tian and Qin 2003, 2004; Cho 2005a; Cho and Jo 2005).…”

This study was performed to determine compensatory growth of juvenile olive flounder fed the extruded pellet (EP) with different feeding regimes. Seven treatments with triplicates of different feeding regimes were prepared; α fish was daily fed for 6 d a week throughout 8 wk (8WF); α fish was starved for 1 wk and then fed for 3 wk twice [(1WS + 3WF) × 2]; β fish was starved for 2 wk and then fed for 6 wk (2WS + 6WF); χ fish was starved for 5 d and then fed for 9 d four times [(5DS + 9DF) × 4]; δ fish was starved for 10 d and then fed for 18 d twice [(10DS + 18DF) × 2]; δ fish was starved for 2 d, fed for 5 d, starved for 3 d, and then fed for 4 d four times [(2DS + 5DF + 3DS + 4DF) × 4]; and φ fish was starved for 4 d, fed for 10 d, starved for 6 d, and then fed for 8 d twice [(4DS + 10DF + 6DS + 8DF) × 2], respectively. Total feeding day was all same, 36 d except for control group (48 d). Weight gain of flounder in the 8WF treatment was higher than that of fish in other treatments. And weight gain of flounder in the 2WS + 6WF treatment was higher than that of fish in the (5DS + 9DF) × 4 and (4DS + 10DF + 6DS + 8DF) × 2 treatments. Feed consumption of flounder in the 8WF treatment was higher than that of fish experienced feed deprivation. Feed efficiency ratio (FER), protein efficiency ratio (PER), and protein retention (PR) were not significantly different among treatments. Chemical composition of the whole body of fish with and without liver, except for moisture content of liver, was not different among treatments. T3 level of fish in the 8WF and 2WS + 6WF treatments was higher than that of fish in the (5DS + 9DF) × 4 treatment. It can be concluded that juvenile olive flounder achieved better compensatory growth at 6‐wk refeeding after 2‐wk feed deprivation compared with that of fish with different feeding regimes. And T3 level of fish seemed to partially play an important role in achieving compensatory growth.

“…Compensatory growth has been reported in cold‐water fish such as salmonids (Bilton and Robins 1973; Miglavs and Jobling 1989; Quinton and Blake 1990; Jobling and Koskela 1996; Damsgaard and Dill 1998) and warm‐water fish such as channel catfish, Ictalurus puntatus (Gaylord and Gatlin 2000, 2001); gibel carp, Carassius auratus gibelio (Xie et al 2001; Zhu et al 2004); red porgy, Pagrus pagrus L.

Compensatory growth of juvenile olive flounder, Paralichthys olivaceus L., and changes in proximate composition and body condition indexes of fish during fasting and after refeeding were investigated during the summer season. Groups of 25 fish each (initial body weight of 16 g) were randomly distributed into fifteen 180-L flow-through tanks. Fish were fed the experimental diet containing crude protein 46.9% and crude lipid 8.0% with estimated energy level of 14.6 kJ/g diet for 6 d/wk. Five treatments in triplicate were prepared for this study: C, S1, S2, S3, and S4. Fish in the control group (C) were hand-fed to apparent satiation twice daily. Fish in treatments S1, S2, S3, and S4 experienced 1, 2, 3, and 4 wk of starvation and were then hand-fed to apparent satiation twice daily during the remaining 7, 6, 5, and 4 wk of the experiment, respectively. A group of starved fish in the similar size was stocked and fasted throughout the 8-wk feeding trial for chemical and blood analysis. The feeding trial lasted for 8 wk. Weight of fish linearly decreased with week of starvation (P , 0.0001). Linear relationship between condition factor (CF) and hepatosomatic index (HSI) against week of starvation was observed in the starved group of fish. Survival was not significantly (P . 0.05) affected by feeding strategy. However, weight gain and specific growth rate (SGR) of olive flounder in C, S1, and S2 were significantly (P , 0.05) higher than those of fish in S3 and S4. The poorest weight gain and specific growth rate (SGR) were obtained in fish of S4. Feed consumption of olive flounder in C, S1, and S2 was significantly (P , 0.05) higher than that of fish in S3 and S4. Feed efficiency, protein efficiency ratio, and protein retention of olive flounder in C and S1 were not significantly (P . 0.05) different from those of fish in S2 but significantly (P , 0.05) higher than those of fish in S3 and S4. Hematocrit, CF, and HSI of olive flounder were not significantly (P . 0.05) affected by feeding strategy. Chemical composition of fish was not significantly (P . 0.05) affected by feeding strategy. In considering these results, it can be concluded that juvenile olive flounder have the ability to fully compensate for 2-wk feed deprivation during the summer season. Besides, feed efficiency in fish fed for 7 and 6 wk after 1-and 2-wk feed deprivation was comparable to that in fish fed for 8 wk.
