영문 초록

This study was performed to define the effects of various levels(0~15%) of dietary yellow loess on growth in Korean rockfish(Sebastes schlegeli). After seven weeks of feeding trial, weight gain, feed efficiency and chemical constituents of muscle were investigated. Chemical composition of yellow loess were composed of SiO₂49.80%, A1₂O₃27.50%, FeO₃8.33%, CaO 0.09%, MgO 0.64%, K₂O 1.62%, Na₂O 0.12%, P₂O5 0.20% and MnO 0.03%. Weight gain and feed efficiency in the 7. 5% and 10% yellow loess group were much higher than those in the other group. Moisture contents of muscle showed higher values the yellow loess addition groups than the control group. Crude protein contents of muscle were not affected by the dietary yellow loess. Crude lipid contents were decreased with dietary yellow loess level. While crude ash contents of muscle were increased with dietary yellow loess level.
