Last spring, we featured UW grad student, Dan Oele’s work on northern pike in Green Bay. Dan was trying to answer the question, “Do pike return to the waters where they first emerged from eggs to spawn, or will any suitable stream do?” Now, it appears he has an answer. And his results are good …
Forgive the late post here, but your trusty blog author has been out and about in the Rocky Mountain front range for the past few days.

Last Tuesday, the United States’ Environmental Protection Agency released the results of a comprehensive study that measured the vital signs of 1.2 million miles of American rivers and streams. The prognosis wasn’t great. Measuring things like water clarity, nutrient pollution, bacteria levels and mercury contamination, the EPA found that 55% of the river miles studied …
Last summer, a team of researchers from the University of Wisconsin–Madison’s Center for Limnology and Wright State University in Ohio, were on the shores of Africa’s Lake Tanganyika, the oldest and deepest of the African rift lakes, for the field season. CFL grad student, Ben Kraemer, decided a summer wasn’t long enough and decided to …
Here in Wisconsin, the end of the work week is often celebrated with a dinner of lightly battered, deep-fried deliciousness. We’re talking bluegill, perch, walleye and, for those not yet hip enough to eat our delectable native fish – cod.
