BERLIN — A German city is looking for a way to get rid of a giant catfish that is believed to have developed a taste for ducklings after eating all of its fellow fish in the municipal pond.

The roughly 4.9-foot fish has been making waves in Offenbach, near Frankfurt. News agency dpa reported that the city government said Monday that it has found a professional angler to catch the fish, first seen about a year ago, but a formal contract has yet to be signed.

The city plans to have its unwelcome guest caught alive and taken to a private pond somewhere, but officials will first have to be satisfied that it can’t escape into flowing water and that its new home is suitable for a catfish.
