MADISON, WI (WTAQ) – When you hear the words “fish sticks,” don’t assume it’s what you’ll have for dinner.
“Fish sticks” is also a term that represents a growing trend in Wisconsin waters. Larger numbers of fallen trees are being placed in lakes and streams, so fish can use them for habitat.
State DNR fisheries’ biologist Scott Toshner says a tree can live for a century, and then spend at least another 100 years helping fish populations in a variety of ways.
Toshner says some species lay their eggs on wood, while others use the trees to protect themselves from larger fish. He says every species of fish uses wood at some point in their lives.
Up to 15 species have been observed living in and around a single submerged tree. Tadpoles, minnows, and other small fish quickly hover in the branches — while shredders and filter feeders start nibbling on the wood, or the algae which soon accumulates.
The state approved general permits a couple years ago, which made it easier to develop tree projects in Wisconsin lakes. There are 29 so far — all but four in the north.
Toshner, who’s based in Brule, says lake associations have been helpful in developing many projects. The state provides up to 75 percent funding.
