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