Become a Lamprey Hunter!

Wisconsin Sea Grant is joining an effort by the Great Lakes Fishery Commission to help track how many sea lampreys are in the Great Lakes and where they are. For 50 years, sea lamprey control efforts have reduced the population by 90 percent in many areas. Despite continuing control efforts, lamprey numbers have rebounded recently in Lake Michigan. Great Lakes fishers can lend a hand by volunteering to become a “Lamprey Hunter.” By keeping track of where they see (and don’t see) lampreys, fishers can help control crews better target their efforts. Visit to learn how to participate, and contact UW Sea Grant Aquatic Nuisance Species Specialist Phil Moy via email at or phone (920) 683-4697.

Mashing Things Up in Web Mapping

David Hart, UW Sea Grant’s geographic information systems specialist, explored the expanding world of “mapping mashups” with urban and regional planning students last spring through a course he taught at UW-Madison. A “mashup” pulls data from different Web sources to produce a unique end product (such as a real estate Web site that maps homes for sale along with information about schools and churches, as well as proximity to businesses like grocery stores and coffee shops). Hart’s students reviewed existing mashups, created tutorials to demonstrate how to build one, and then created their own mapping mashups to meet a social or business purpose. Their final projects ranged from mapping routes, amenities, and points of interest for a bicycle tour around Lake Michigan to visualizing Amtrak monthly ridership data between Milwaukee and Chicago over a period of eight years. The final projects are posted at
