对虾病毒病与化学需氧量相关关系研究

A STUDY ON THE RELATIONSHIP BETWEEN COD AND SHRIMP VIRAL DISEASE

通过对虾池内主要环境因子与对虾病毒病相关关系的研究 ,发现虾池内化学需氧量(COD)太高是诱发对虾病毒病暴发流行的主要环境因子之一。利用多级S型净化池可以大幅度消除水体中的COD 。

There is a close relationship between COD and shrimp viral disease. COD is one of the important environmental conditions for breaking out shrimp epidemic virosis. The 'S' type multistage purification pond was very good for removing COD considerably and prevented effectively from breaking out shrimp epidemic virosis.
