Evaluation of Extruded Pellets and Raw Fish-Based Moist Pellet for Growth of Sub-Adult Flounder Paralichthys olivaceus
Year: 2008
Type: article
Abstract: This study was conducted to evaluate extruded pellets (EP) for the growth of sub-adult flounder Paralichthys olivaceus by comparing with raw fish-based moist pellet (MP). Two replicate groups of 150 fish per each tank (initial mean weight 594±6.5 g) were fed one of two EPs (EP1 and EP2) and a MP for 32 weeks. Survival was not significantly affected by experimental diets. Final mean weight of fish fed the EP1 was not significantly different from that of fish fed the MP, but that of fish fed EP2 was significantly lower than that of fish fed EP1 and MP (P＜0.05). Feed efficiency and protein efficiency ratio of fish fed the EP1 and EP2 were significantly higher than those of fish fed MP (P＜0.05). Daily feed intake of fish fed the EPs was significantly lower than that of fish fed MP (P＜0.05). Condition factor was not significantly different among all groups. The contents of moisture, crude protein and lipid in dorsal muscle were significantly affected by experimental diets (P＜0.05). Based on the results of this study, the dietary formulations used in EP1 and EP2 could be applied in the practical extruded pellet feeds for sub-adult flounder (594-1,126 g).
