中文摘要：以体长为(1.13±0.07)cm的大海马幼鱼为研究对象,观察复合微生态制剂AQ菌和EM菌对大海马幼鱼生长与存活及水中pH、化学需氧量(COD)、氨氮(NH_+~4-N)和亚硝酸盐氮(NO_2^--N)含量的影响。实验设二个处理组AQ菌组(A)和EM菌组(B),均保持养殖水体中有益菌浓度约1×10~4 CFU/mL,另设对照组C(不加复合微生态制剂)。经过35 d实验,结果表明:AQ菌和EM菌对幼鱼的生长及水质影响效果相差不大(P>0.05),都可促进幼鱼生长和提高成活率;能够提高水中的pH值,维持在7.7~8.2的适宜范围;有效降低水中COD、NH_4^+-N和NO_2^--N含量,与对照组相比,分别降低了31.0%、51.8%和68.3%,表现出显著性差异(P<0.05)。

外文摘要：Effects of complex probiotics AQ and EM on growth, survival and water contents of pH, chemical oxygen demand （COD）, ammonia nitrogen （NH4＋-N）, nitrite nitrogen （NO2-N） were studied by using body length was （1.13±0.07）cm of Hippocampus kuda Bleeker Juvenile. The experiment lasted for 35 days and three groups AQ （A） , EM （B）, control group （C, no complex probiotics preparation was added） were set up and A,B group had three replicates, maintain probioties in aquaculture water concentration about 1 ×10^4 CFU/mL. Results showed that the effect of AQ and EM were not statistically significant （P〉0.05） in growth of juvenile and water quality： both could promote the Hippocampus kuda Bleeker juvenile grow and improve survival rate and to improve the water pH, keep in the suitable range of 7.7 - 8.2 and effectively reduce the COD, NH4＋N, NO2-N content in water. Compared with the control group, was reduced by 31.0%, 51.8% and 68.3%, respectively, which there were signific.antly difference （P 〈 0.05 ） by multivariate analysis.
