Fish being taught how to eat on command
Fish species at a Chicago aquarium are to be taught how to eat on command.
They will also be trained to gather at a designated area of their pools at the Shedd Aquarium to make feeding time as orderly as possible.
Among the first students are groups of sharks, including a 4-foot blue Napoleon wrasse, a blue-blooded species with the ability to change sex.
"What we're trying is probably the most complex training effort ever attempted with fish," said Bert Vescolani, vice-president for the Shedd's aquarium collections.
Rachel Wilborn, a Shedd worker, recently used a mechanical clicker to catch the attention of some of her pupils, three zebra sharks named Freckles, Blondie and Seymour.
"They come right up to the side and ask for food, but to get it, they have to touch a rubber bulb on the end of a pole with their snouts," she said.
The three hit the bulb and got tuna steaks as a reward.
Even Trogg should be able to catch something then [
