Abstract Most hatcheries use live microalgae and algae powder for artificial rearing; however, the effects of these different diets on the rearing process and bacterial communities is not clear. In order to investigate the effects of live algae and algal powder on the larval culture of Penaeus monodon. Two kinds of live algae (Chaetoceros muelleri, Thalassiosira weissflogii) and Spirulina powder were used to feed larvae in this study, and the effects on the environmental parameters of water, the digestive enzymes activity of larvae and the bacterial community from the zoea stage to the post larval (PL) stage were explored. The results revealed that feeding larvae with C. muelleri significantly improved the enzymatic activity of amylase and the survival rate of the larvae, and significantly reduce the concentrations of NH4-N, NO2-N and the quantity of Vibrio in the water (P

活微藻及藻粉对斑节对虾不同生长阶段微生物群落、存活、变态及消化酶活性的影响

摘要 大多数孵化场使用活的微藻和藻粉进行人工养殖；然而，这些不同饮食对饲养过程和细菌群落的影响尚不清楚。为了研究活藻和藻粉对斑节对虾幼体培养的影响。本研究采用两种活藻类（Chaetoceros muelleri、Thalassiosira weissflogii）和螺旋藻粉喂养幼虫，研究了从藻类阶段到藻类阶段对水环境参数、幼虫消化酶活性和细菌群落的影响。后幼虫（PL）阶段进行了探索。结果表明，用C. muelleri喂养幼虫显着提高了淀粉酶的酶活性和幼虫的存活率，并显着降低了NH4-N的浓度，
