WebMay 30, 2013 · Abstract. Fish resist being swept downstream by swimming against a current. Mexican blind cavefish (Astyanax fasciatus) exhibit this innate behavior, rheotaxis, without the aid of vision, but it has been debated whether this ability requires sensing flow with the lateral line system.We tested the role of the lateral line by comparing swimming … WebThe sensory basis of rheotaxis (orientation to currents) was investigated in the blind Mexican cave fish, Astyanax fasciatus.An unconditioned rheotactic response to uniform velocity flows was exhibited, with a threshold of less than 3 cm s −1.Disabling the entire lateral line or the superficial neuromast receptor class increased the rheotactic threshold …
WebDec 15, 2015 · Many fish exhibit rheotaxis, a behavior in which fish orient themselves relative to flow. Rheotaxis confers many benefits, including energetic cost savings and interception of drifting prey. Despite the fact that most species of fish school during at least some portion of their life, little is known about the importance of rheotactic behavior to … WebJan 18, 2024 · During rheotaxis swimming, the fish rapidly aligns its body with the uniform flow and holds position for more than 200 periods. Two types of wake vortex patterns are identified for rheotaxis swimming.
WebNov 1, 2013 · Rheotaxis is a robust, multisensory behavior with many potential benefits for fish and other aquatic organisms. Visual (optic flow) cues appear to be sufficient for rheotaxis, but other sensory cues can clearly compensate for the loss of vision. Nevertheless, the nature of multisensory interactions … WebFish resist being swept downstream by swimming against a current.
