Feb. 12 (UPI) -- A Wisconsin spear fisherman landed a gargantuan 171-pound sturgeon estimated to be about 130 years old.

Jon Eiden said he was fishing Monday with his father, John Eiden, when he landed the 85.5-inch-long sturgeon on Lake Winnebago.


The Wisconsin Department of Natural Resources said the 171-pound fish, estimated to be about 130 years old, was tagged at the Shawano Dam in 2012.

Eiden said catching the old fish was bittersweet.

"Whenever you take a trophy like that, whether it's a whitetail, or a sturgeon. But it's part of the conservation, and happy to be a part of it," he told WLUK-TV.
