Interactions of dietary eicosapentaenoic acid and vitamin C on growth performance, anti-oxidation and muscle quality of abalone Haliotis discus hannai Ino

A 93-day feeding trial was conducted to investigate the effects of dietary eicosapentaenoic acid (EPA) and vitamin C (VC) on the growth performance, anti-oxidation and muscle quality of abalone Haliotis discus hannai (initial body weight: 26.89 ± 0.26 g; initial shell length: 60.36 ± 0.25 mm). Six experimental diets in a 3 × 2 two-factor design were formulated with graded levels of dietary EPA (0.25%, 0.75% and 1.25%) and dietary VC (0 and 1260 mg/kg). Results showed that the weight gain rate (WGR) of abalone was significantly increased with the increasing dietary EPA levels (P
