| 摘 要： | 研究了由球形红假单胞菌(Rhodopseudomlonas sphaeroides)、噬菌蛭弧菌(Bdellovibrio bacteriovorus)及黏红酵母(Rhodotorula glutinis)制成的4种微生态制剂对中国对虾(Fenneropenaeus chinensis)育苗水质的影响.结果表明,试验组与对照组相比都能明显净化水质,试验组中以添加噬菌蛭弧菌和黏红酵母组的效果最差,添加球形红假单胞茵和噬茵蛭弧茵组的效果最好,此组水质的pH值稳定,NH4+-N明显下降,而亚硝酸盐、化学需氧量及硫化物等指标也优于其他试验组.统计分析显示,试验组与对照组相比,细菌数降低了3个数量级,添加嗜菌蛭弧菌试验组在减少异养茵(包含有害细菌)方面效果较好.同时用鳗弧菌攻毒,在5 d内,对照组的死亡率显著高于试验组(P<0.05),试验组免疫保护率为29.4%～58.5%,以添加嗜菌蛭弧菌和球形红假单胞菌组最高.建议联合使用噬菌蛭孤菌和球形红假单胞菌,混合密度初步定为2×105个/mL.

| Abstract: | Rhodopseudomlona sphaeroides,Bdellovibrio bacteriovorus and Rhodotorula glutinis were added to the water for the feed of Fenneropenaeus chinensis larvae under the experimental conditions.The results showed that compared with the control group,all the test groups can obviously purified the water quality.The effect of the test group to which were added B.bacteriovorus and R.glutinis,was the worst,while the group to which was added R.phaeroides and B.bacteriovorus was most effective for purifying the water in ... |
