Scientists at the University of Wisconsin-Madison are conducting groundbreaking research on ?lake mixing? as a tool to control fish species composition.Deep lakes tend to stratify into two layers, the upper layer warm and the lower layer cold. Different fish species require different water temperatures, so mixing the lake can have major implications for some sensitive fish species.
?Nothing like this has been done before,? said Jake Vander Zanden, professor of limnology and zoology at UW-Madison, referring to mixing up the lake?s temperature zones.
