WebMost aquatic animals can navigate in complex flow environments. Fish, for example, can consistently orient and swim against oncoming flow (rheotaxis) even without visual cues. Rheotaxis is a challenging process that involves multiple steps, including flow sensing and motor control. Previous studies proposed a data-driven model of rheotaxis in which fish … WebRheotaxis is a response to a current in a fluid. Positive rheotaxis is shown by fish turning to face against the current. In a flowing stream, this behaviour leads them to hold their position in a stream rather than being swept downstream. Some fish will exhibit negative rheotaxis where they will avoid currents.
