The effect of three different diets (formulated diet, FD; Undaria pinnatifida, UP; Laminaria japonica, LJ) on growth in the Haliotis discus hannai for 90 days was investigated. The shell length of UP (80.62 ± 1.92 mm) and LJ (81.14 ± 1.16 mm) were significantly faster than those of FD (79.38 ± 1.69 mm) (P < 0.05). However, shell breadth and total weight were no significant difference among three diets. On the other hand, the weight gain of FD (16.65% for 0-45day and 25.71% for 45-90day) tend to have higher than those of UP (14.57% and 23.30%) and LJ (12.65% and 24.51%). This results shows that seaweed diets (UP and LJ) help the shell growth of abalone and formulated diet (FD) help the weight gain of abalone. Therefore, the growth of shell and muscle will depend on different diets.
