Development of series artificial diets for abalone and its culture efficiency

The studies on developing series artificial diets with different diet prescription, production technics and its culture efficiency for Abalone larval, juvenile and adult had been carried out.The results showed that Abalone larval fed with the artificial diet instead of part of diatom adhered to board 10 days longer than that only fed diatom, seedling output and survival rate increased by 30%—40% and 15%—20% respectively, average growth rate of Abalone juvenile of 3.5 mm fed on the diet for 66 days was 169 μm·d-1, average growth rate of adult of 25 mm fed adult diet for 90 days was 172 μm·d-1, average weight gain was 105 mg·d-1, average feed coefficient 2.0.which were 20 μm·d-1, 12 mg·d-1 higher and 0.1 lower than those of one commercial diet which was 152 μm·d-1, 93 mg·d-1 and 2.1 respectively.
