Ask a fisheries biologist: A roundup of Wisconsin’s fall fish surveys

As is often the case, we saw a mixed bag of results in the fall surveys in Wisconsin.

Juvenile walleye are the main target. We found small to medium walleye year classes on the usual producers, including Chippewa Flowage, Round, Sand and Windigo lakes. We also assessed stocking survival on a few lakes, with moderately positive results on Chetac, the Spider chain and Sissabagama.

Muskies are a secondary target in these surveys. Reproduction looked strong on Black Dan and Barber.

We also saw many bass as a result of the warmer water temperatures. Largemouth bass on Nelson, Chetac, and the Tiger Cat Chain had very good size.
