For the preservation and restoration of ecosystems in agricultural canals, it is important to quantify not only the characteristics of preferable habitat such as water quality and hydraulic condition but also environmental preference of fish or wildlife. In this research, environmental preference of Japanese Medaka Fish (Japanese killifish, Oryzias latipes) and hydraulic environments in agricultural canals were investigated by laboratory experiments and on-the-spot examinations. Japanese Medaka Fish was selected as a river fish subject to this research because Japanese Medaka is now regarded as the symbolic fish for the restoration of countryside ecosystems in Japan.Judging from the hydraulic measurements in and around artificial blocks that are recently constructed for providing fish nest in agricultural canals, the three environmental factors of water depth, current velocity and cover were selected as the principal factors affecting the availability and quality of the fish habitat in … More agricultural canals. Based on the background that fish behavior is essentially noncommittal and that the behavioral responses to an environmental change vary widely among both individuals and circumstances, the preference intensities of Japanese Medaka to the three environmental factors were quantified by fuzzy logic modeling and laboratory open-channel experiments. A simple genetic algorithm was introduced to search for the optimal functional representation of preference intensity. The fuzzy-GA preference intensity model was then successfully verified by laboratory water-tank experiments and on-the-spot examinations. The good agreement between the predicted and observed distributions in considering the two factors of current velocity and cover indicated that the two factors obviously affected the environmental preferences of Japanese Medaka.For the purpose of evaluating the environment of fish habitat through the individual-based model approach, the schooling behavior of Japanese Medaka was analyzed to determine the interactions between individuals : the spacing between individuals, the spatial distribution of individuals and the communication processes. The behavioral pattern model was introduced to describe the behavior of fish schooling. The results of the numerical simulations using the model agreed with the experimental data in many regards, including the polarization, the nearest neighbor distance, the expanse and the fractal dimension.The differences of swimming behavior among individuals were also quantified by calculating return map, fractal dimension, correlation dimension and wavelet transform for swimming trajectory, swimming velocity and turning angle respectively The feasibility of the assessment for the degree of tension or rest of fish in specific environment and the fish-based biomonitoring for chemical contaminants in water environment was examined using the calculated results.

为了保存和恢复农业管中的生态系统，不仅量化了首选栖息地的特征，例如水质和氢聚糖状况，而且还要量化鱼类或野生动植物的环境偏好。在这项研究中，通过实验室实验和现场检查，研究了日本Medaka鱼（日本杀虫剂，Oryzias latipes）和农生环境的环境偏好。日本的甲麦加鱼被选为这项研究的河鱼，因为现在被认为是日本恢复日本乡村生态系统的象征性鱼类。根据最近在人工块中及其周围构建的氢化测量结果，这些测量最近是为在农业管中提供的，在农业巢中提供的质量，当前景点的质量，范围内的三个环境因素，范围内的三个环境因素，范围内的三个环境因素。 …更多的农业运河。基于背景，鱼类行为本质上是非官员的，并且对环境变化的行为反应在个人和环境之间差异很大，日本Medaka对三个环境因素的偏好强度通过模糊逻辑建模和实验室开放通道实验来量化。引入了一种简单的遗传算法，以搜索偏好强度的最佳功能表示。然后，通过实验室水坦克实验和现场检查成功验证了模糊的GA偏好强度模型。在考虑当前速度的两个因素时，预测和观察到的分布之间的良好一致性表明，这两个因素显然影响了日本Medaka的环境偏好。目的是通过基于个体的模型方法评估鱼类栖息地的环境，分析了日本Medaka的教育行为，分析了个人之间的相互作用以确定个人之间的间距：个人之间的间距分配，并分配了个人的交流和跨越的分布。引入了行为模式模型来描述鱼类学校的行为。数值模拟的结果使用该模型与许多方面的实验数据一致，包括极化，最近的邻居距离，延伸和分形维度。在特定的环境和水环境中化学污染物的基于鱼类的生物监测中，使用了计算结果。较少的
