Abstract
In order to investigate the n-3 highly unsaturated fatty acids (n-3HUFA) requirement of the Korean rockfish Sebastes schlegeli, two experiments were conducted in the flush-out aquarium system. 1. Effects of different dietary fatty acids on growth and feed efficiency Efficacy of different fatty acids on the Korean rockfish was investigated by feeding diets containing each of the different fatty acids, 12:0, 18:1n-9, 18:2n-6, 18:3n-3, and n-3HUFA for 9 weeks. The best growth and feed efficiency were obtained from the fish fed diet containing n-3HUFA (P<0.05). 2. n-3HUFA requirement Requirement of dietary n-3HUFA for the Korean rockfish (5.9 g in mean body weight) was investigated with the test diets containing different levels of n-3HUFA ranging from
