Fish are proficient in sensing hydraulic conditions and are well adapted to moving in their liquid environment. When fish attempt to overcome challenging hydrodynamic conditions, they can wait for supportive water flow conditions and choose the most energy efficient routes. In my research, I explore the relationship between hydrodynamic stimuli and the swimming behaviour of fish using modern technologies, such as Particle Image Velocimetry, Computational Fluid Dynamics, Video tracking, and Acoustic telemetry. Machine learning appoaches, such as Random Forest or Artificial Neural Networks, are used to identify and visualize complex patterns within these multivariate data sets.
