Kalamazoo Lake is an important area for adult sturgeon migrating up the Kalamazoo River to spawn, officials said.
“Survival of the eggs and fry exceeded expectations this year,” said DNR fisheries supervisor Dave Borgeson.
Researchers from Grand Valley State University’s Annis Water Resources Institute have been awarded a $50,000 one-year grant from the Match-E-Be-Nash-She-Wish Band of Pottawatomi Indians, the Gun Lake Tribe, to study lake sturgeon in the Kalamazoo River.
The first of nine rock reefs is under construction in the St. Clair River delta northeast of Detroit. The goal of the project, which is led by Michigan Sea Grant, is to boost populations of lake sturgeon and other rare native fish by providing river-bottom rock structures where they can spawn.
