光合细菌对养殖水体的生态调控作用

Micro-ecological requlation of photosynthetic bacteria in maricutural pond waters

本文报道了养殖池施用光合细菌后，水中异养细菌、弧菌、发光细菌和光合细菌的消长情况，研究了它们的相互关系。结果表明，添加光合菌后，池水中光合细菌数量增加而弧菌和发光菌数量减少，表明了光合细菌具有调节养殖环境做生态系的作用。

In the shrimp culture ponds, Photo Synthetic Bacteria (PSB) were applied regularly.The number of heterotrophic bacteria, vibrios, photogenic bacteria and PSB in pond waters was monitored, and the growth and decline of these microorganisms and their relationship were preliminarily studied. The results showed that with the increase of PSB in number, the number of vibrios and photogenic baiteria decreased and indicated that PSB can regulate the micro ecosystem in the maricultural pond waters.
