HEI Biologists Assist with Mussel Survey and Relocation Project

As part of a mussel survey and relocation project, biologists at Holland Engineering completed snorkel surveys of the Huron River in metro Detroit. Due to the new mussel protocol requirements and tight project deadlines, this project had to be completed quickly and efficiently.

Michigan releases new mussel protocols for 2018. Are you up to date?

Freshwater mussels are filter feeders who burrow in the substrate of rivers, streams, and lakes throughout the world. The U.S. alone is home to some 300 species. According to the U.S. Fish and Wildlife Service (USFWS) and the Nature Conservancy, approximately 70 percent of mussel species in North America are extinct or endangered. Michigan contains four federally listed species (six including two not found in the state since 1930) and twenty-six additional state-listed mussel species (all federally listed species are also listed in the state). Two of the state-listed species will be reviewed by the USFWS for possible federal listing before 2023.
