Kinematical features of locomotion -basis of fish control management in zones of influence of hydrotechnical structures

Abstract

The structural analysis of the locomotion of various fish species presented in this work opens the possibility to take a fresh look at the solution of the problem of controlling fish behavior in a stream - through the prism of the kinematic structure of vortex structures generated by fish in the course of their swimming by different styles. In the locomotion of fish, there is an analogy with the phenomenon of the superimposition of two "antagonistic" forms of the jet stream - the wakeful (behind the streamlined object) and the flooded turbulent stream.

The parameters of flow-forming elements for controlling the behavior of fish in artificial channels

“…A review where the main studies on the problems and results of the analysis of the hydraulic structure of a turbulent flow in interaction with the body of various fish species and the characteristics of the behavior of fish in a water flow are considered is given in works (Pavlov and Pakhorukov, 1983;Fish Protection at Water Diversions, 2006;Borovskoy and Mikheev, 2011;Mikheev et al, 2019Mikheev et al, , 2020.…”
