" 'If you've caught a male bass during the spawning season, that means it will have trouble guarding the nest for quite awhile', says Dr. Jason Schreeer, an assistant professor of biology at the State University of New York in Potsdam.
While at the University of Waterloo in Waterloo, Ontario, Schreer and two associates looked at the effects of forced exercise on smallmouth bass.   In effect, they used a 'treadmill for fish' to investigate "Cardiac Response to Variable Forced Exercise at Different Temperatures: An angling Simulation for Smallmouth Bass'.
The treadmill consisted of tubes in which the velocity of water flowing past the fish could be controlled. "It wasn't perfect, he says. "The smallmouth didn't have a hook in its mouth, and it wasn't subjected to air'."
