Effect of dietary nutrient composition on the growth of olive flounder (Paralichthys olivaceus) with different feeding regimes

Abstract

We have examined the effect of dietary nutrient composition on the growth, body composition and blood chemistry of juvenile olive flounder (Paralichthys olivaceus) maintained on two different feeding regimes. Three experimental diets [HP (high protein), HE (high energy) and IPE (intermediate protein and energy)] were crossed in a two-factor design with the two feeding regimes, which consisted of 2WS + 2WF (2-week starvation and then 2-week feeding) and 4WS + 4WF (4-week starvation and then 4-week feeding)], for 8 weeks. The total days of feeding in all treatments were the same. The final weight of fish was affected by feeding regime, but not by dietary nutrient composition. Long-term starving and feeding (the 4WS + 4WF treatments) yielded higher growth than the alternating short-term starving and feeding regime (2WS + 2WF treatments). The feed consumption of fish was affected by dietary nutrient composition, but not by feeding regime, while the feed efficiency of fish was affected by feeding regime, but not by dietary nutrient composition. Moisture, crude protein and crude lipid contents of the liver of the fish were affected by dietary nutrient composition, but not by feeding regime.

Growth performance and body composition in response to dietary protein and lipid levels in Nile tilapia (Oreochromis niloticus Linnaeus, 1758) subjected to normal and temporally restricted feeding regimes

“…This was pronounced in the treatments in the diet containing high protein and lipid levels. Similarly, feeding high dietary protein alone or in a combination of high dietary protein and lipid led to higher feed intake, which generated a better CG response in previous studies with olive flounder (Cho et al., ; Cho, ) and channel catfish (Gaylord and Gatlin, ). An improvement in feed efficiency was also observed in fish fed the 36% protein diets versus fish fed the 30% protein diet in this study.…”

“…Nutrition is an important factor that must be considered in effective aquaculture management otherwise the fish would be unable to get enough energy to fuel their rapid growth (Gaylord and Gatlin, ; Ali et al., ; Wu et al., ). Several researchers have given attention to the significance of nutrition in the regulation of CG response (Gaylord and Gatlin, ; Turehini et al., ; Cho et al., ; Cho, ; Cho and Heo, ). The desired effect of CG in fish might be achieved with proper nutrition regardless of which feeding regime is adopted.…”

“…Additionally, inconsistent CG responses have been reported in the literature (Ali et al, 2003). In fact, the extent of the CG response appears to vary on a species-specific basis (Hayward and Wang, 2001;Zhu et al, 2001;Ali et al, 2003) and is affected by factors such as water temperature (van Dijk et al, 2005), feeding regime (Zhu et al, 2001;Cho et al, 2010;Morshedi et al, 2013), sex (Barreto et al, 2003), degree of maturity (Jobling et al, 1994), diet composition (Gaylord and Gatlin, 2001;Turehini et al, 2007;Cho, 2011;Cho and Heo, 2011), feeding trial duration (Gaylord and Gatlin, 2001;Ali and Jauncey, 2004;Wang et al, 2009), and the extent of feed deprivation or restriction (Quinton and Blake, 1990;Saether and Jobling, 1999;Zhu et al, 2001;Turano et al, 2008;Sevgili et al, 2012).…”

Effect of restricted feeding and refeeding on compensatory growth, nutrient utilization and gain, production performance and whole body composition of carp cultured in earthen pond

“…Cho et al . () 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 . We also observed that due to restricted feeding and refeeding, there was a significant change in lipid and ash contents in all the three carp species.…”
