Fish behavior is one of the essential indicators, not only for evaluating the water environments following the impact of development activities on river ecosystems, but also for estimating the functional aspects of river improvement. In contrast to the past ecological studies that have tried to explain the preferences of fish from field measurements in a natural habitat, our study is directed toward developing a methodology for such evaluations with the aid of numerical simulation techniques. The final goal of our study is to evaluate the fish preference in a hydraulic environment by numerical simulations with a fish school model and the observed hydraulic data around the hydraulic structures. In this project, mathematical models for predicting the fish behavior to various hydraulic environments in agricultural canals have been examined by using water tank experiments and numerical simulations.First, the water tank experiments were executed to characterize the schooling behavior of Jap … More anese Medaka fish (Oryzias latipes). Several characteristic variables were introduced to quantify the global structure and the typical characteristics of a fish school in the experiments : the nearest neighbor distance, the polarization and the expanse. The fractal dimension, the return map and the correlation dimension, which are the parameters proposed in the field of chaos engineering, were also used to characterize the nervous strain of fish individuals in the given environment.Next, the Newtonian dynamics model and the behavioral pattern model were investigated to simulate the schooling behavior obtained in the water tank. The comparison of both models showed that the behavioral pattern model could reproduce the characteristic variables of real fish school more accurately. The artificial neural network model could also simulate the schooling behavior obtained in the water tank experimentsFinally, the hydraulic experiments using an open channel were carried out in order to determine the preference curves for the hydraulic environments such as the water depth, the flow velocity and the shield factor.

鱼类行为是必不可少的指标之一，不仅用于评估开发活动对河流生态系统的影响，而且还用于估算河流改善的功能方面。与过去试图解释自然栖息地中鱼类偏好的过去的生态学研究相反，我们的研究旨在借助数值模拟技术来开发这种评估的方法。我们研究的最终目标是通过使用鱼类学校模型的数值模拟以及在氢化结构周围观察到的氢化数据来评估氢化环境中的鱼类偏好。在该项目中，已经通过使用水箱实验和数值模拟来检查用于预测农业运河各种氢化环境的鱼类行为的数学模型。首先，执行了水箱实验以表征日本的教育行为…更多的是Anese Medaka Fish（Oryzias latipes）。引入了几个角色变量，以量化实验中鱼类学校的全局结构和典型特征：最近的邻居距离，极化和扩展。分形维度，返回图和相关维度（这是混乱工程领域提出的参数）也被用来表征给定环境中鱼个个体的神经压力。next，Newtonian Dynamics模型和行为模型模型被研究以模拟在水箱中获得的教育行为。两种模型的比较都表明，行为模式模型可以更准确地重现真实鱼类学校的特征变量。人造神经元网络模型还可以模拟在水箱实验中获得的学校行为，进行了使用开放通道的氢化实验，以确定水深度，流速和盾构因子等氢化环境（例如水深，流速和盾构因子）的偏好曲线。较少的
