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.

为探讨利用鱼类呼吸和游动活动监测镉等亚急性和慢性有毒物质及农药的可行性。1991年，研究了(1)鱼类回避行为对镉的检测灵敏度；(2)3种农药在鱼体中的累积速率。研究发现，鱼类的回避行为可以检测到1/10的LC_(50)浓度，而氯丙酯在鱼类体内的蓄积量更大，毒性也更强。1992年，(1)对鱼类呼吸活性指标的数据采样方法进行了调查；(2)对几种鱼类的呼吸活性进行了数据采集。研究发现，用计算机采集的数据与实际呼吸活动相吻合，蓝鳃是适合于这一目的的鱼类之一。1993年，研究了(1)检测呼吸活动异常的数据分析方法；(2)检测农药对呼吸活动的亚急性毒性效应的敏感性。发现鱼的呼吸活动可能能够检测到低于LC_(50)值的浓度。
