八九月间,由于恰逢高温,对虾需氧量很大,所以,这期间内最容易发生对虾浮头现象。笔者总结了一些养虾户和养虾单位多年来的经验教训认为,如果喂养水面不超过2亩地的小型虾池,采取以下措施将是增加溶解氧,防止对虾浮头的一个十分有效的方法。 In August and September, due to the high temperature, the demand for prawn oxygen was very high. Therefore, the phenomenon of floating prawns was most likely during this period. The author summarizes the experiences and lessons learned by some shrimp farmers and shrimp producers over the years. If feeding small shrimp ponds with no more than 2 mu of water on the surface, the following measures will be a very effective way to increase dissolved oxygen and prevent shrimp from floating head.
