“…This probably resulted from differences in fish size, water temperature, and/or the duration of feeding trials among the studies. SGR (0.22%/day) of grower olive flounder in the 12WF-C treatment in this study was comparable to that (0.20%/day) of grower fish averaging 287 g fed a commercial diet to satiation once a day at a mean temperature of 12.1°C for 15 weeks (Kim et al, 2009) and within values (0.18-0.56%/day) obtained from grower fish averaging 255 g fed diets containing various protein and lipid levels daily at 15.5°C for 14 weeks (Kim et al, 2010). Therefore, growth of grower olive flounder in the 12WF-C treatment in this study seemed to be relatively well achieved.…”

“…Therefore, there is a body of evidence indicating that manipulation of dietary nutrient composition can affect the compensatory growth of fish. A variety of feeding trials with juvenile olive flounder have been reported (Kikuchi, 1999;Lee et al, 2000;Alam et al, 2002;Kim et al, 2005;Cho et al, 2006b;Kim et al, 2006;Lee et al, 2006); on the other hand, only a few feeding trials (Kim et al, 2009(Kim et al, , 2010 at suboptimal temperatures involving grower fish have been performed to date. Kim et al (2010) reported that the optimum dietary protein and lipid levels for grower olive flounder averaging 255 g were 45% and 14%, respectively, at 15.5°C and were equivalent to an estimated energy level of 17.4 kJ/g diet.…”

“…Generally speaking, grower olive flounder must overwinter to grow up to highly valuable marketing size at fish farm. To date, there have been only few studies with grower olive flounder ( Kim et al, 2009 ) compared to studies with juvenile fish ( Iwata et al, 1994 ; Cho, 2005 ; Huang et al, 2008 ; Cho and Heo, 2010). In addition, no study on compensatory growth of grower olive flounder has been performed yet.…”

Compensatory growth of grower olive flounder (Paralichthys olivaceus) was determined at suboptimal temperature (13.0±1.9°C). Fifteen fish averaging 201.1 g per tank were distributed into 18 of 300 L flow-through tanks. Six treatments were prepared in triplicate: fish were hand-fed with an extruded pellet to apparent satiation once a day for 16 weeks (16 WF); and the other five groups of fish were hand-fed for 15, 14, 13, 12 and 10 weeks after 1-, 2-, 3-, 4- and 6-week feed deprivation, referred to as 15 WF, 14 WF, 13 WF, 12 WF and 10 WF, respectively. A linear relationship between body weight of fish and feed deprivation was observed: Y (Body weight of fish) = −1.81X (Weeks of feed deprivation)+201.07, R2 = 0.83. Weight gain of grower olive flounder in 15 WF, 14 WF, 13 WF and 12 WF treatments was comparable to that of fish in 16 WF treatment, but lower than that of fish in 10 WF treatment. Specific growth rate of fish in 15 WF treatment was higher than that of fish in 16 WF, 14 WF and 10 WF treatments. Feed consumption of fish was not affected by feeding regime. Feed and protein efficiency ratios of fish in 15 WF treatment were higher than those of fish in 13 WF, 12 WF and 10 WF treatments. Grower olive flounder could achieve full compensatory growth when fish were daily fed for 12 weeks after 4-week feed deprivation at suboptimal temperature.

“…그리고 수온 역시 어류의 성장에 영향을 미치는 중요한 환경인자 중의 하나로서 (Brett et al, 1979), 수온이 낮아지면 어류 체내 의 소화효소 활성 및 대사율이 감소하게 되어 (Fauconneau et al, 1983) 먹이 섭취량이 적어지고, 수온이 상승하게 되면 활동성 및 대사율 증가로 사료 섭취율도 증가하기 때문에 수온에 따른 적정 사료 공급율 및 공급횟수를 설정하는 것이 매우 중요하다. 넙치 사육을 위한 사료공급체계에 관한 연구 는 주로 넙치의 성장에 적합한 여름철에 대부분 수행되었으며 (Lee et al, 2000;Kim et al, 2007a;Kim et al, 2009a), 저수온기 의 경우 치어 및 미성어에 관한 연구가 일부 수행되었으나 (Kim et al, 2007b;Kim et al, 2009b) (Hung and Lutes, 1987;Kim et al, 2007a). 철갑상 어 및 gilthead sea bream과 같은 타 어종에서도 본 연구와 유사한 결과를 보였다 (Hung et al, 1989;Mihelakakis et al, 2002).…”

“…그러나 평균수온 11-12℃에서 치어기 넙치 (6-13 g, 45-53 g)를 대상으로 한 연구에서는 1일 2회로 만복 공급하는 것이 바람직하다고 보고되었으며 (Kim et al, 2005;Kim et al, 2007b), 수온 12℃에서 미성어기 넙치 (270-350 g)의 경우, 적정 사료공급 횟수는 1일 1회로 나타나 (Kim et al 2009b), 어체 크기에 따른 적정 사료공급 횟수에 차이를 보였으며 어체의 크기가 증가함에 따라서 감소하는 경향을 보였다. 어류의 최대 성장을 위한 적정 사료공급 횟수는 어체 크기 뿐 아니라, 어종, 사료의 영양소 함량 및 수온과 같은 사육환경 등에 의해서도 달라질 수 있는 것으로 알려져 있다 (Wang et al, 1998;Lambert and Dutil, 2001;Dwyer et al, 2002;Riche et al, 2004).…”

Two 15-week feeding trials were conducted to investigate how the rate and frequency of feeding affected the winter growth of olive flounder (13℃). In the first experiment, triplicate groups of fish (initial mean weight 117±6.0 g) were fed extruded pellets twice a day at feeding rates of 0.1, 0.25, 0.4, 0.55, and 0.57% (satiation) body weight per day (BW/d). The weight gain, specific growth rate, and feed efficiency increased significantly (P<0.05) with the feeding rates from 0.1 to 0.55% BW/d, but no significant differences in these parameters were found for fish fed diets of 0.55% BW/d and satiation. The moisture and ash contents of whole body of fish tended to decrease as the feeding rate increased, but the opposite trend was found for crude lipid content. In the second experiment, triplicate groups of fish (initial mean weight 117±6.3 g) were fed extruded pellets to apparent satiation at the three different feeding frequencies: one meal 2 days, one meal a day and two meals a day. The weight gain and specific growth rate of fish fed one meal 2 days were significantly (P<0.05) lower than those of fish fed one or two meals a day, whereas no significant differences in the weight gain and specific growth rate were found between fish fed one and those fed two meals a day. Feed efficiency and condition factor were not significantly affected by feeding frequency. Based on these results, a feeding rate of 0.3% BW/d is recommended as maintenance feeding level, and the optimum feeding frequency is one meal a day with satiation feeding for the growth of olive flounder (117-147 g) during winter (13℃).
