Researchers will take to Green Bay next month to see whether a member of the herring family is making a comeback. The Cisco had a thriving history in the waters around Door County in the 1930s through the 1950s, when pollution and other factors began decimating the species. The U.S. Fish and Wildlife Service will use the Kewaunee-based Research Vessel Stanford H. Smith to net and assess the populations of the Cisco and other fish species. Fisheries Biologist Ted Treska says if there are signs the Cisco stocks are returning that's good news for the waters of Green Bay.
Treska says Cisco populations are thriving in eastern Lake Michigan where they're being caught in abundant numbers from break walls and other locations near Charlevoix.
