HOW FISH HANDLE EDDIES

摘要

Most experiments that look at how fish swim observe the animal's movements in smooth flowing water; however, the real world isn't like that. Fish routinely encounter swirls and eddies that threaten to throw them off course; but by how much and how do they cope? Hans Tritico now at Youngstown State University, USA, and Aline Cotel at the University of Michigan, USA, decided to find out how eddies affect creek chub by putting the fish in a turbulent water tunnel and filming the water's motion and the fish's responses (p. 2284).
