Scientists Try For 'Remote-Control Fish' Researchers Seek To Bolster Bass Stock

Boston -- Call them Pavlov's fish.
Scientists are testing a plan to train fish to catch themselves by swimming into a net when they hear a sound that means feeding time.
A marine researcher said, "It sounds crazy, but it's real."
He said these "remote-control fish" could someday be used to bolster the depleted stock of black sea bass.
The bigger goal is to defray costs of fish farming, an important source of the world's seafood.
Previous experiments have used sound to train a fish to feed -- similar to what Russian scientist Ivan Pavlov did to get his dogs to salivate at the sound of a bell.
But no one has ever tried to get fish to leave and come back ready to be caught.
The research at the Marine Biological Laboratory at Wood's Hole is funded by a $270,000 grant from the National Oceanic and Atmospheric Administration.
