Koi Pond Regulations in Washington State: WDFW Import Rules
Washington State WDFW has banned the import of live non-native fish without prior approval under its Aquatic Invasive Species rules. For koi dealers and hobbyists in Washington, this means that importing koi requires advance authorization, not just accompanying paperwork at the point of entry. You need approval before the fish are shipped.
Washington has some of the strictest non-native species import regulations in the US, and the regulatory framework is enforced. WDFW conducts spot inspections of licensed dealer facilities, and dealers using manual records frequently fail these inspections due to incomplete or disorganized quarantine documentation.

WDFW Import Approval Process
Before importing koi into Washington State, dealers must apply for and receive import approval from WDFW's Fish Program. The approval process involves submitting information about the source facility, fish species and quantities, health certification from the source state or country fish health authority, and the intended quarantine facility in Washington.
WDFW may impose conditions on import approvals, including specific quarantine periods, mandatory disease testing, and documentation requirements. Importing koi without prior WDFW approval violates the state's Aquatic Invasive Species regulations and can result in seizure of fish and permit revocation.
Dealer Licensing Requirements
Washington koi dealers need a WDFW Fish Dealer License. Dealers that also breed koi need a Fish Farming License or Aquatic Farmer Permit depending on their operation type. The conditional nature of koi import approval means license status alone is not sufficient for each import. Each lot requires individual authorization.
WDFW conducts periodic inspection of licensed facilities to verify that holding systems prevent escape into natural waterways and that quarantine and health documentation is current and complete. The inspection format is similar to federal USDA APHIS audits but focuses on Washington's specific documentation requirements.

Hobbyist Implications
Washington hobbyists ordering koi from online retailers located outside Washington need to verify that the seller understands Washington's import approval requirement. This is more demanding than most states. A seller who ships frequently to California or Oregon may not be familiar with Washington's pre-approval process.
Buying koi that arrive in Washington without WDFW import approval puts the buyer in a difficult position. The fish may technically be in violation of Washington AIS law regardless of the buyer's intent or awareness. Dealing with established, Washington-experienced importers who understand the pre-approval process is strongly recommended.
Releasing koi into Washington's natural waterways is illegal and carries serious penalties. Washington has an active AIS enforcement program that treats illegal fish releases as serious violations.
Documentation That WDFW Inspectors Look For
Based on WDFW inspection patterns, the key documentation areas for facility reviews include:
- Current import approval documentation for each active lot
- Health certificates from source state or country
- Quarantine start and completion dates
- Water quality test records during quarantine
- Disease findings and treatment records if applicable
- Clearance documentation before fish move to display or retail holding

Who needs Koi Pond Regulations in Washington State: WDFW Import Rules?

Look for health certificates issued by a licensed veterinarian in the origin state, clear quarantine records, and familiarity with WDFW's advance approval requirements.
