Fish rheotaxis
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 … WebMay 1, 2015 · Rheotaxis is a widespread behavior with many potential benefits for fish and other aquatic animals, yet the sensory basis of rheotaxis under different fluvial conditions is still poorly understood.

WebMay 3, 2012 · Zebrafish larvae show a robust behavior called rheotaxis, whereby they use their lateral line system to orient upstream in the presence of a steady current. At 5 days post fertilization, rheotactic larvae can detect and initiate a swimming burst away from a continuous point-source of suction. Burst distance and velocity increase when fish … WebAug 2, 2014 · Fish activity is quantified in terms of rheotaxis and tail-beat frequency measured automatically by tracking fish shape. Fish social behavior is quantified in terms of average nearest neighbor distance (ANND) and polarization. Results show that both social behavior and individual activity are significantly affected by change in temperature.

WebJul 18, 2024 · However, several questions remain unanswered, including how blind fish can perform rheotaxis or whether a passive hydrodynamic mechanism can support the phenomenon. One aspect that has been overlooked in studies of rheotaxis is the bidirectional hydrodynamic interaction between the fish and the surrounding flow, that is, … WebJun 6, 2024 · For over a century, scientists have sought to understand how fish orient against an incoming flow, even without visual and flow cues. In this study the researchers explore a potential hydrodynamic mechanism of fish rheotaxis — movement away or toward water currents — through the study of the bidirectional coupling between fish and …
