NEW LONDON - A spring ritual is underway in Wisconsin. And, it's an early start to the sturgeon spawning run on the Wolf River.
Dozens of the large, ancient fish spawn in shallow river water west of New London. State Department of Natural Resources sturgeon biologist Ryan Koenigs says the spawning season has started about nine days earlier than usual. And it could last just a few days.
Biologists say some male sturgeon migration every spring, but the females make the trip every three to five years.
