Lake Michigan Top Destination for Fishing

Lake Michigan was the most popular place to fish during 2006–2007, according to results of a statewide mail survey of anglers holding Wisconsin fishing licenses.

However, nearly three-quarters of angler’s trips were made to waters other than Lake Michigan, Lake Winnebago, the Mississippi River and the Wisconsin River, hinting at the diversity of fishing in a state with 15,081 lakes and 42,000 perennially flowing miles of river.

Anglers spent more than 71 million hours on Wisconsin waters, and although walleye was their most targeted species, they caught more panfish than anything else. In total, 88.2 million fish were caught in Wisconsin during the 2006–07 license year, and anglers released nearly two thirds.

New Project to Address Climate Change Impacts on Wisconsin

A new statewide project will assess the potential consequences of climate change for Wisconsin’s ecosystems, industries, farms and human health and will recommend adaptation strategies.

The Wisconsin Initiative on Climate Change Impacts (WICCI) will organize teams of experts from the University of Wisconsin-Madison, state agencies and other institutions to consider how local and regional shifts in temperature, precipitation and extreme weather could affect key components of the state’s quality of life.

Great Lakes Waterfowl Threatened by Botulism

Thousands of waterbirds have died from type E botulism around the Great Lakes, and researchers say invasive species might be to blame.

It appears that quagga and zebra mussels filter out the botulism toxin from nearby mats of decaying Cladophora algae and then they’re eaten by fish such as the invasive and highly abundant round goby. The infected gobies, which become paralyzed by the toxin, are then easy prey for flocks of migrating, fish-eating waterbirds, such as common loons, red-necked grebes, and long-tailed ducks.
