It is the mission of the Museum of Biological Diversity Fish Division to build a strong representative collection of North American freshwater fishes with secondary strengths in Mexico and Central America. To build a strong collection from lakes, rivers, and streams of Ohio with the best documentation available; this includes a repository for all the states' rare, threatened and endangered voucher specimens. To maintain an ongoing relationship with the state of Ohio agencies involved in fish research. These include Ohio Department of Natural Resources Division of Wildlife and the Ohio Environmental Protection Agency Division of Surface Waters.  (Sometimes, however, we acquire specimens from farther away!)
