Koi Pond Regulations in Illinois: IDNR Requirements for Dealers and Hobbyists
Illinois classifies koi as a restricted species under its Wildlife Code, requiring dealers to obtain aquaculture dealer licenses. Illinois koi dealers who rely on informal knowledge of IDNR rules face compliance gaps that can surface unexpectedly during inspections. The Illinois Wildlife Code's classification of koi as a restricted species means that commercial dealings with koi require specific licensing, and the documentation requirements that come with that licensing are detailed.

Illinois IDNR Regulatory Framework
The Illinois Department of Natural Resources (IDNR) regulates koi under the Wildlife Code's restricted species provisions. Key requirements for Illinois koi dealers:
Aquaculture dealer license. Commercial koi dealers in Illinois must hold an IDNR aquaculture dealer license before importing or selling koi. The license application requires documentation of facility compliance with IDNR standards, including containment requirements and health record-keeping commitments.
Health certifications. Imported koi must have valid health certifications from the state of origin. IDNR health certification requirements cover koi herpesvirus and spring viremia of carp screening, the two diseases of greatest concern under Illinois's aquatic invasive species framework.
Quarantine records. Illinois requires licensed dealers to maintain quarantine records documenting the isolation period, health observations, and release criteria for all imported fish. Records must be available for IDNR inspection.
Federal requirements. Federal USDA APHIS requirements apply in addition to Illinois state requirements. The koi dealer import compliance guide covers the federal framework.
Hobbyist Considerations in Illinois
Illinois koi hobbyists keeping fish in properly contained backyard ponds for personal enjoyment generally don't need an aquaculture dealer license. The dealer license requirement applies to commercial sales. However, hobbyists should be aware that:
- Releasing koi into Illinois public waterways is prohibited
- Illinois ponds with drainage connections to natural waters may face scrutiny if koi escape
- Selling or trading koi without an aquaculture dealer license puts hobbyists in violation of the Wildlife Code
