摘要:Abstract: We analyzed the bait feeding in broodstock strength, artemia-feeding stage and copepods feeding stage of the red grouper Epinephelus akaara. The result shows that the survival rate of the oyster- feeding broodstock is 89.33%, the fertility rate of the egg is 78.9% and the hatching rate is 80.1% which are significantly higher than those of white shrimp feeding-group and razor clam-feeding group (P < 0.05); when the offspring reaches the artemia-feeding stage, we feed them with fish oil (4 g/L) wrapped by strengthening Chlorella + rotifers astaxanthin (5 g/L) instead and the survival rate is 29.53%; the growth rate of the total length is 175.00% which has the best effects. The survival rate and the growth rate of the total length are significantly higher than other groups when we feed the fish with oil package (4 g/L) package copepoda and astaxanthin (5 g/L) in the copepods feeding stage of the red grouper. Finally, the survival rate and the growth rate of the total length significantly increase (P < 0.01) when the red grouper is feed with soft particle bait (eel powder:anchovy = 3:2, with 5 g/kg astaxanthin) in the later stage.
