Abstract:

Group behaviors formed by organisms or objects due to cluster properties are common in nature. The study of group behavior helps human beings to deeply understand the natural world and provides theoretical guidance for intelligent cluster control. Individual interactions of fish schools can induce neighboring fish bodies to share information, thus improving the success rate of fish migration. In this study, fish upstream behavior experiments were carried out under the self-constructed ecological fish passage, and individual and school upstream experiments were carried out by setting semicircular obstacles to create a low-turbulence flow field. Based on the YOLOv5 algorithm, we captured the high-precision fish movement trajectories of the fish group under different flow conditions, and combined them with the results of numerical modeling to obtain hydraulic indicators. Track the passive swimming behavior of fish in the experimental area, and count the characteristic parameters of each interaction behavior. Combined with the hydraulic indicators at the location where the behaviors occurred, the response relationship between the movement strategy of the fish throughout the upstream journey and the perceived flow field was comprehensively derived. Through the analysis of fish interaction behaviors, flow field preference, and the influence of sidewalls, a two-dimensional cluster rule model of the fish population was established based on the principle of minimum potential energy. The results of this study are helpful in deconstructing the dynamic upstream process of fish in specific migratory scenarios. It will provide a system of quantitative indexes for the interactive movement of carp, which can be applied to specific behavioral scenarios such as the test of the swimming ability of fish, the deconstruction of upstreaming behaviors, and also provides inspiration for the design and control of future robotic swarming formations.
