WHO CAN DO FRESHWATER MUSSEL SURVEYS?• The Ohio Division of Natural Resources (ODNR) and United
States Fish and Wildlife Service (USFWS) publishes a list of approved surveys in Ohio annually
• The list is comprised of both ODNR only and USFWS permitted individuals
• ODNR Approved Surveyors: • Permitted individuals who can only complete work on
streams where no federally listed species are known• Tend to be less experienced surveyors
• USFWS Approved Surveyors:• USFWS permitted individuals can complete work in
streams with state and federally listed species • Federally permitted individuals tend to have more
experience• Important to request a copy of your selected contractors
permit, as the results of surveys completed by a non-permitted individuals will likely not be excepted

America with 71% of the 300 species considered endangered, threatened or of special concern
• Relatively complex and interesting life cycle• Includes a host fish and
a parasitic life stage

WHERE DO MUSSEL SURVEYS NEED TO BE COMPLETED?

REFER TO THE OHIO MUSSEL SURVEY PROTOCOL
• Joint document created by ODNR and USFWS
• All streams listed in Appendix A of the Ohio Mussel Survey Protocol (or any stream with >10mi2 of drainage) require a mussel survey.

WHY ARE MUSSELS SUDDENLY SUCH AN ISSUE IN OHIO?

MUSSELS HAVE REGULATORY AUTHORITY
• OHIO: All mussels are protected in the State of Ohio (Section 1533.324 of the Ohio Revised Code).
