This experiment was conducted to clarify the adequate and excess amounts of n-3 highly unsaturated fatty acids (HUFA) in the diet for juvenile striped jack, Pseudocaranx dentex. Experimental diets were formulated to contain 65% white or brown fish meal as protein source. Dietary lipid contents and n-3HUFA levels were adjusted to about 15% and 1.5-6.1%, respectively, using triglycerides (EPA 28 oil), a n-3HUFA mixture (Ester 85), beef tallow and palm olein. After a 10-week feeding experiments, best weight gain and feed efficiency along with the lowest hepatosomatic index (HSI) were observed in fish fed diets containing 2.3-3.4% n-3HUFA. Further elevation of dietary n-3HUFA content resulted in reduced growth and increased HSI. In the liver, moisture contents decreased and crude lipid contents increased with increase of dietary n-3HUFA level.<BR>It is suggested that adequate levels of n-3HUFA in the diet and in the dietary lipid for juvenile striped jack are 2.3-3.4% and 15-25%, respectively, whereas excess amounts are more than 4.8% and 30%, respectively, at the 15% dietary lipid level.
