The sneaky folks over at the Marine Biological Laboratory at Wood’s Hole, Massachusetts have a three step plan to improve fishing. Step one: train fish to respond to specific sound frequencies. Step two: let fish go out into the wild and get plump and fat. Step three: use said sound to call fattened fish back, willingly getting themselves caught for consumption.
The project is being funded by a $270,000 from the National Oceanic and Atmospheric Administration and so far it's had limited success. The researchers are trying to see how effective the sound broadcasts are at coaxing fish into feeding areas — some fish forgot the signal's meaning after five days, while others reacted to the sound for up to ten.
In May, the scope of the project will be much larger, using the AquaDome in Buzzards Bay as a two-day boot camp to train fish to return to their voracious masters.
