Escape rescue system of fishes from Hypoxia using natural energy

提出了一种利用自然能量的缺氧水体上涌降低鱼类死亡率的系统，并对其可行性进行了研究。为了解鱼类的氧变化规律和回避行为，对鱼类的水质和生态行为进行了全面的观测。3-鱼类的尺度行为与溶解氧的变化相对应，其阈值与实验数据基本一致。数值模拟的案例研究结果表明，曝气系统不能恢复足够的氧气水平，在缺氧的最坏情况下，鱼类的生存，但它可以在足够的氧气的情况下是有用的。在地表水里。

The system which reduces the mortality of fishes by upwelling of oxygen-depleted water(hypoxia), based on the natural energy, was proposed and its feasibility was studied. Overall observations of water quality and ecological behaviors of fishery fishes were conducted for clarifying the oxygen variability and following avoidance behavior of fishery fishes. 3-dimensional behavior of fishes occurred corresponding to the variation of dissolved oxygen and their threshold values were almost coincident with the experimental data. Results of case studies of numerical simulations suggested that the aeration system could not recover the oxygen level enough for fish survival in the worst case of hypoxia, but that it could be useful in the case with the enough oxygen. in the surface water.
