【Abstract】 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.更多还原
