对养殖水体的溶氧进行自动、连续监测,无论是为养殖实验提供数据,还是用于现场监测,以防突发性缺氧使生产遭受损失,都具有重要的意义。在海洋水质监测中,自动连续溶氧监测仪器已广泛使用,但在水产养殖中,由于水体中大量的浮游生物、碎屑、鱼体排泄物的存在,使得安装于现场用于 The automatic and continuous monitoring of dissolved oxygen in aquaculture water is of great significance both for providing data for aquaculture experiments and for on-site monitoring so as to prevent sudden hypoxia from losing production. In the marine water quality monitoring, automatic continuous oxygen monitoring instruments have been widely used, but in aquaculture, the presence of a large number of plankton, debris, fish excrement in the water makes installation on site
