Abstract

|
A eight weeks feeding experiment was conducted to investigate the effects of different dietary dimethyl-β-propiothetin (DMPT) levels on growth and chemical components in Korean rockfish (Sebastes schlegeli). The content of DMPT extracted from Enteromorpha intestinalis by autoclaving was 31.1 mg%. Body weight gain and feed efficiency were significantly increased with dietary DMPT level. After eight weeks of feeding trial, moisture content decreased with supplemented DMPT level, while crude protein and lipid contents increased with dietary DMPT level. Amino acid contents of muscle was elevated in the DMPT added groups compared to control group. Amino acid composition of muscle in fish fed the diets supplemented DMPT was not different to that of control group. Fatty acid contents of muscle in fish increased with dietary DMPT level.
