Abstract (in Japanese) (See Japanese page) 
(in English) It is well known that the physiological activity presents complex behavior, and that chaos and fractals analyses are considerably effective to understand the complexity. Then, in this report, we aim to improve environmental load evaluation methods based on change of the chaos and fractal characteristics. First, we extract the action potential of a fish which doesn’t depend on visual information as a biological signal with an indoor water tank. In experiments, environmental loads are added to the water of the indoor water tank, and we verify the existence of the chaos movement loci by means of the Fractal Dimensions, analyzing the influence of the environmental loads on these loci from a view point of chaos and fractal characteristics. In conclusion the result shows that the dependence on the environmental loads can be found from the chaos and fractals analysis.
