From Spiegel….

Berlin Zoo had put the carp into his moat to help keep the water clean by eating algae. But the 140-kilo (309-pound) bear shocked onlookers by catching the chubby fish and playing with his live prey until they stopped flapping. Then he gobbled them up.

“He ate them all in just a day and a half,” the zoo’s bear expert Heiner Klös told SPIEGEL ONLINE. “Whatever people may say, he’s a good hunter, and it’s all part of being a polar bear. This shows he’s totally fit. We won’t be placing any more fish in his moat, though.”

Germany’s top-selling daily Bild reported that onlookers were disgusted by the spectacle. The newspaper ran the headline “Knut Embroiled in Carp Scandal” and quoted animal welfare campaigners as criticizing the zoo for letting Knut eat live vertebrates in breach of German animal protection regulations.
