Comparison of Various Fish Meals as Dietary Protein Sources for Korean Rockfish, Sebastes schlegeli

Two experiments were conducted to investigate the utilization of various types of fish meal as dietary protein sources in Korean rockfish (Sebastes schlegeli). In the first experiment, averaging 5.7 g fish were divided into two groups and fed one of diets containing steam-dried white fish meal (SWFM) or brown fish meal (BFM) for 45 days. Weight gain and feed efficiency from fish fed SWFM were significantly (P SWFM, flame-dried white fish meal (FWFM), , or hydrolyzed fish protein (HFP) for 21 weeks. No significant differences were found among fish fed the six different diets in weight gain, feed efficiency, condition factor, whole body composition, and relative liver weight. Results of the present studies indicated that fish size should be considered in selecting feed ingredients and also feed cost could be lowered by replacing SWFM with FWFM or BFM in growing Korean rockfish diet.
