| 摘 要： | 人工引入光合细菌于凡纳滨对虾养殖环境中,监测与养殖环境相关的水质因子(氨氮、亚硝酸氮、化学需氧量)的变化;观察不同光合细菌使用浓度下凡纳滨对虾对人工制造的胁迫环境的抗逆性;观测不同光合细菌使用浓度下凡纳滨对虾的成活率与体重增长率。研究光合细菌对水质改善和凡纳滨对虾抗逆性的影响。结果表明,光合细菌能显著(P<0.05)降低水体中的化学需氧量、氨氮含量并抑制亚硝酸盐氮的产生;当光合细菌投放浓度为3×103cfu/mL时,水体中化学需氧量、氨态氮、亚硝酸盐氮含量的均值分别比对照组降低了31.59%、43.42%、52.20%;成活率比对照组提高了18.67%,体重增长率是对照组的1.34倍;当光合细菌使用浓度为3×102cfu/mL~3×104cfu/mL时,对虾抗逆性显著(P<0.05)增强,对虾在氨氮、亚硝酸盐氮、高锰酸钾、甲醛胁迫下24 h的成活率均值分别比对照组提高了36.67%、25.00%、26.39%、10.00%。

| Abstract: | Different concentrations of Photosynthetic bacteria were introduced into culture environment of larval Penaeus vannamei.In the course of experiment,nitrite nitrogen,ammonia and COD were measured.15days after the introduction of Photosynthetic bacteria,the survival rate,the raise rate of the weight and the stress resistance were measured.The comparative test results between treatment and control groups showed that the introduction of Photosynthetic bacteria in appropriate density could significantly(P<0.05) ... |
