Michigan DNR's Regulatory Framework

Michigan DNR regulates koi under the Natural Resources and Environmental Protection Act (NREPA), which gives the DNR broad authority over non-native species introduction. Key requirements:

Import restrictions. Michigan DNR restricts koi importation to approved sources that meet health certification requirements. Not all koi importers are approved sources for Michigan. Dealers need to confirm that their import sources are acceptable under Michigan DNR's framework before placing orders.

Approved import route guidance. KoiQuanta's Michigan import route guide helps dealers navigate which import sources and transport pathways are compliant with Michigan DNR requirements. Using an unapproved import route, even if the fish are otherwise healthy, creates regulatory violations.

Health certifications. All imported koi need health certifications that meet Michigan DNR's disease screening standards, particularly for KHV, SVCV, and other notifiable diseases.

Dealer permits. Commercial koi dealers in Michigan need appropriate DNR permits for their operation type.

Hobbyist Implications in Michigan

Michigan koi hobbyists face restrictions beyond what many states impose. The NREPA framework means:

Purchasing koi from out-of-state sources requires confirming those sources meet Michigan DNR requirements
Releasing koi into Michigan waterways is strictly prohibited
Pond drainage to natural waterways requires appropriate containment to prevent escape

Michigan hobbyists who buy koi at out-of-state koi shows or from internet retailers should verify that those sources have the health certifications Michigan requires before transporting fish into the state.

The koi dealer import compliance guide covers the federal USDA requirements that apply alongside Michigan DNR state requirements.
