Objects of this research was to study the possibility of monitoring methods for sub-acute and chronic toxic substances such as Cadmium and agricultural chemicals by using respiratory and swimming activity of fish.In 1991, (1) detection sensitivity for Cadmium by avoidance behavior of fish and (2) accumulation rate of three agrochemicals in fish body were investigated. It was found that avoidance behavior of fish will be able to detect 1/10 of LC50 concentration, and that Chloropropylate was more accumulated in fish body and more toxic than other two agro-chemicals.In 1992, (1) the data sampling methods for the indicator derived from respiratory activity of fish and (2) respiratory activity of several fishes were investigated. It was found that the data collected by computer coincided with actual respiratory activity, and Blue Gill is one of the suitable fish for this purpose.In 1993, (1) the method for data analysis to detect the abnormal respiratory activity, and (2) sensitivity for the detection of sub-acute toxic effects of agro-chemicals on respiratory activity were investigated. It was found that respiratory activity of fish may be able to detect the lower concentration than LC50 value.

这项研究的目的是研究通过使用鱼类的呼吸道和游泳活性来监测亚急性和慢性有毒物质（例如镉和农业化学物质）的可能性。1991年，（1）通过避免鱼类的避免行为的cadmium敏感性，并研究了三种农业剂在鱼身体内的累积率。发现鱼类的回避行为将能够检测到1/10的LC50浓度，并且比其他两种农业化学物质在鱼体中积累更多，毒性更具毒性。在1992年，（1）（1）研究了来自鱼类的呼吸活性和（2）呼吸道活性的数据样本方法，该指标被研究了几种鱼类的呼吸活性。发现通过计算机收集的数据与实际的呼吸活性相吻合，而蓝ill是适合此目的的合适鱼类。（1）（1）研究了数据分析的方法，用于检测异常的呼吸系统呼吸系统，并研究了对农业化学对呼吸系统活性的亚急性毒性作用的敏感性。发现鱼的呼吸活性可能能够检测到低于LC50值的浓度。
