“…Twelve-month hybrid abalones were obtained from the grading station in ZhongXin Yongfeng (Fuzhou, China) in early April 2022. Studies have shown the color of male and female abalone gonads was milky white and grayish green, respectively (Shepherd and Laws, 1974;Vélez-Arellano et al, 2015). Abalones were acclimated and fed a commercial diet for two weeks in the sh steak of abalone farm in Lianjiang Country, Fujian Province before the experiment.…”

A natural feed of fresh seaweed and sixteen diets designed by L16 (43) orthogonal array were formulated to contain differentlevels of protein (200, 250 g, 300, 350 g/kg), α-Vitamin E (VE) (0, 0.1, 0.3, 0.5 g/kg) and Vitamin E (VC) (0, 0.5, 1, 1.5 g/kg) to evaluate the effects of dietary protein, VE, VC and their combination on growth and gonadal development of hybrid male abalone (Haliotis fulgens ×H. discus hannai ). Each diet was randomly assigned to triplicate groups of 18 abalones (34.27±2.93 g) that were stocked in sea cages for eight weeks. Results showed that the maximum weight gain (WG) and speci c growth rate (SGR) were obtained in hybrid male abalone fed D10 diets. The highest gonad somatic index (GSI) value was found in the D14 diet. Moreover, the ANOVA results showed that only dietary protein could signi cantly affect the GSI of hybrid male abalones (P < 0.05). The mRNA expression of vasa in the testis of D14 abalone was the lowest. Abalones fed the D14 diet had higher testosterone level and sperm in testis than those fed other diets. In conclusion, protein of 300 g/kg, VE of 0.1 g/kg and VC of 1.5 g/kg (D10) and protein of 350 g/kg, VE of 0.1 g/kg and VC of 1 g/kg (D14) might be the optimal combinations in the diet for growth and gonadal development of hybrid male abalones respectively.
