What's the Catch

Remember Charlie the Tuna from those commercials? Charlie was constantly trying to finagle a way to be selected for processing (why he would want to be filleted and canned is another question).

Today, it turns out scientists are working on a way to turn fish — and not just tunas — into Charlies eager to get caught, gutted and IQF'd. The strategy is based on conditioning them with a Pavlovian response to a sound they associate with food. Scientists would play the sound just before releasing food into the water. Later, after the fish are at mature weight, the same sound would lure them into a net for harvesting.

Sorry, Charlie.
