Fish Studies Show Walleye Thrive

The walleye population in the Tittabawassee River is thriving and reproducing naturally, based on recent findings from the Michigan Department of Natural Resources (DNR).

The DNR conducted a study in 2003 that showed a significant increase in natural walleye reproduction compared with previous years. The 2003 results show that about 72 percent of walleye studied reproduced naturally in the Saginaw Bay and its tributaries, and only 28 percent of the walleye were planted by DNR fish hatcheries. In studies conducted in previous years, only about 20 percent of walleye from Saginaw Bay were reproducing naturally.

A separate study conducted by the DNR also showed that walleye egg production, hatchability and short-term survival were equal to or greater than that of other areas in Michigan.

Each year, the DNR takes millions of eggs taken from walleye and sends them to its Wolf Lake Fish Hatchery. When the eggs hatch, the young walleye are used to stock several rivers all over the state of Michigan, including the Tittabawassee.

Results from the most recent DNR study on egg production show that eggs taken from walleye on the Tittabawassee survived at a rate similar to those taken from walleye on the Muskegon River, and better than eggs taken from walleye in the Little Bay de Noc, in Michigan’s Upper Peninsula.
