BOSTON (AP) - Call them Pavlov's fish: Scientists are testing aplan to train fish to catch themselves by swimming into a net when
they hear a sound that means feeding time.
A marine researcher says, "It sounds crazy, but it's real." He
says 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.
