Influence of 18:2n-6/20:5n-3 ratio in diets on growth and fatty acid composition of juvenile abalone, Haliotis discus hannai Ino

A 120-day feeding trial was conducted to examine the effects of the ratio of dietary linoleic acid (LA, 18:2n-6) to eicosapentaenoic acid (EPA, 20:5n-3) on the growth and fatty acid composition of juvenile Haliotis discus hannai (initial shell length 10.23 ± 1.48 mm; initial body weight 0.13 ± 0.05 g) in a recirculation water system. Five semipurified diets with 35 g kg−1 total lipid were formulated to contain graded LA/EPA ratios (1 : 0, 0.75 :...
