New Ohio Mussel Survey Protocols Announced

Region 3, May 10, 2013

The U.S. Fish and Wildlife Service, Ohio Ecological Services Field Office and the Ohio Department of Natural Resources, Division of Wildlife are pleased to announce the release of joint agency Mussel Survey Protocols for the State of Ohio. These protocols were developed to provide standardized guidance to project applicants about acceptable survey methods and levels of effort for a variety of common project types. These protocols are adapted for Ohio from “West Virginia Mussel Survey Protocols, March 2013, by Clayton et al.” These protocols are generally applicable to all streams in Ohio that may harbor mussels.


Many Ohio streams have been assigned into one of four groups for the purpose of determining the appropriate survey effort and protocol to follow. Survey protocols are based on stream size and potential for the presence of federally listed mussels. Regardless of stream group classification, all four groups of streams require a mussel survey. Streams not assigned into a group should also be assessed to determine if habitat for native mussels is present. Mussel surveys may also be recommended for these streams.
