This study was conducted to evaluate the effects of replacing dietary fish oil (FO) with poultry oil (PO) in a diet for olive flounder, Paralichthys olivaceus. In the experiment, triplicate groups of 15 juvenile olive flounder averaging 3.93±0.07g (mean±SD) were fed one of the seven experimental diets. Seven diets were formulated to replace FO with PO at 0% (PO₀), 25% (PO<SUB>25</SUB>), 50% (PO<SUB>50</SUB>), 75% (PO<SUB>75</SUB>), and 100% (PO<SUB>100</SUB>). Additionally, two treatments were replaced FO with PO at 68.6% and docosahexaenoicacid (DHA) at 14.4% (BT<SUB>68.6</SUB>D<SUB>14.4</SUB>), and PO at 82.8% and DHA 17.2% (BT<SUB>82.8</SUB>D<SUB>17.2</SUB>) of diet, respectively. At the end of 8-week feeding trial, weight gain (WG) and specific growth rate (SGR) of fish fed PO 50% diet were significantly lower than those of fish fed PO 75% and PO 100% diets (P<0.05). However, WG and SGR of fish fed control diet were not significantly different from those of fish fed the other diets. There were no significant differences in feed efficiency and protein efficiency ratio of fish fed the experimental diets. Survival rate (%) of fish fed the all diets were not significantly different. Replacing FO with PO had no adverse effects on measured indices of serological parameters and whole body composition (P>0.05) after the 8-weeks feeding trial. Reducing FO up to 75% significantly decreased whole-body EPA, DHA and total n-3 fatty acids (P<0.05) relative to control group; while, whole-body DHA had no significant differences between control and DHA supplemented group (P<0.05).
Based on the results of growth performance, we concluded that PO can be potentially replaced with FO up to 100% in the diet containing 53.9% of fish meal for juvenile olive flounder.
