Fish adaptability flow velocity test simulation system and method
The invention relates to a fish adaptability flow velocity test simulation system and method. The system is characterized in that the water inlet side in a test water tank is divided into a plurality of channels by partition plates, each channel is connected with a branch water inlet pipe, the upstream ends of all the branch water inlet pipes are gathered and connected to a main water inlet pipe, the main water inlet pipe is connected with a water pump, each branch water inlet pipe is provided with a control valve and a flow meter, an upstream steady flow grid and a downstream steady flow grid are arranged in the test water tank in the water flow intercepting direction, and each channel is divided into a buffer channel and a test channel by the upstream steady flow grid. The method comprises the following steps: setting the flow velocity of a test channel, putting a plurality of fishes, and recording the number of fishes in each test channel after the fishes swim to each test channel in a dispersed manner; attracting the fished to out of the test channels by using baits, and after the fishes swim to the test channels in a dispersed mode, recording the number of the fishes in the test channels again; and obtaining the adaptive flow velocity of the fishes after multiple times. According to the invention, adaptive flow velocities of fishes of different types and month ages can be tested.
本发明涉及一种鱼类适应性流速试验模拟系统及模拟方法，该系统为试验水箱内部进水侧被隔板分割成多个通道，每个通道均连接一个分支进水管，所有的分支进水管的上游端汇总连接到总进水管，总进水管连接有水泵，每个分支进水管分别设置有控制阀门和流量计，试验水箱内拦截水流方向设置有上游稳流格栅和下游稳流格栅，上游稳流格栅将各个通道分割成缓冲通道和测试通道。该方法包括设置好测试通道流速后，放入多条鱼，待鱼分散游到各个测试通道后，记录各测试通道中的鱼数量；鱼饵引诱出测试通道，待鱼分散游到各个测试通道后，再次记录各测试通道中的鱼数量；多次后得出鱼的适应性流速。本发明测试得到不同种类、月龄的鱼的适应性流速。
