- Description
- Point locations for collections of Michigan fish The data set was created to facilitate production of point maps showing distributions of fish in Michigan, both historical and current. The data came from MDNR (approximately 63,000 records, 5000 sites, dating from 1923), UMMZ (35,000 records, 4700 sites, dating from 1874), United States Geological Survey, Great Lakes Science Center (USGS/GLSC) (34,000 records, 4600 sites, dating from 1958), United States Fish and Wildlife Service (USFWS) (33,000 records, 4100 sites, dating from 1947), Michigan River Inventory (MRI) (8000 records, 546 sites, dating from 1937). University of Michigan Center for Great Lakes and Aquatic Science (UM/CGLS) (1,400 records, 100 sites dating from 1982) and miscellaneous sources (600 records, 600 sites, dating from 1923). The MRI collections were made by Drs. Paul W. Seelbach, Michael J. Wiley and students from the UM School of Natural Resources and Environment combined with collections made mostly on large rivers by the MDNR. The UM (CGLS) collections were made by Dr. David Jude. Hybrids and unidentified species were excluded from all data sets. In the UMMZ collections, the identification of species has been painstakingly addressed and voucher specimens are available for amost all of the fish collections. However, in the other collections identification of species is accepted but, in most cases, no voucher specimens for verification of identity are available.
