Selling live non-native aquatic organisms in Michigan
Registration with the Michigan Department of Natural Resources (DNR) is required for any person selling, or possessing for the purpose of selling, non-native aquatic species. This applies to wholesale vendors, retail vendors and shops, hobbyists and water garden retailers and nurseries. Entities must register yearly with the DNR. A separate registration is required for each location of sale. Anyone selling at trade shows must register separately for each sale event.
A confirmation number is provided for each registration. The seller is required to retain and conspicuously post the confirmation number at the sale location as proof of registration. Registration expires on Dec. 31 of the issuing year and must be updated each year.
Reporting the sale of non-native aquatic organisms
Anyone registered with DNR must also report sale information. Registrants are required to report the name and number of individuals of each aquatic species sold using the online reporting form. Some species are exempt from reporting; however, all sellers must submit a report regardless of the species sold. Reporting should cover sales from Jan. 1 to Dec. 31.
