acoustic ranching
n.— «Researchers at the Marine Biological Laboratory in Woods Hole hope to prove fish can be trained to associate certain sounds with feeding, by putting thousands of black sea bass in a dome-shaped structure at the bottom of Buzzards Bay, and feeding them pellets after playing a tone underwater. After they are released to supplement their diet with natural forage, the hope is they will return to the dome for recapture. “Basically the whole concept is: What if you can go out in the ocean and call only the fish you want into the net?”…The process is called “acoustic ranching,” Miner said, and is basically akin to Ivan Pavlov’s dogs, except underwater and with fish.» —“Buzzards Bay experiment aims to train fish to jump into the net” by Aaron Gouveia SouthCoastToday.com (Massachusetts) Mar. 4, 20008.
