Koi Pond Regulations in New Jersey: NJDEP Dealer Compliance Guide

By KoiQuanta Editorial Team|Updated Mar 2026

New Jersey DEP requires koi dealers to obtain aquatic species import permits and maintain treatment and koi quarantine program records for two years. New Jersey DEP regulations are among the most detailed for koi dealers in the mid-Atlantic region. The two-year records retention requirement, combined with the specific documentation standards for treatment and quarantine records, creates a compliance burden that dealers who rely on paper logs routinely struggle to meet.

KoiQuanta's New Jersey DEP compliance module documents every permit, health certificate, and quarantine record required by NJ regulations, generating compliant documentation from daily management activities without separate record-keeping workflows.

New Jersey DEP Regulatory Requirements

The New Jersey Department of Environmental Protection (NJDEP) regulates koi under its Division of Fish and Wildlife's exotic species and aquaculture framework. Key requirements for New Jersey koi dealers:

Aquatic species import permits. New Jersey koi dealers must obtain NJDEP aquatic species import permits before commercial koi importation. The permit application includes documentation of containment facilities and health record-keeping commitments.

Two-year record retention. NJDEP requires treatment and quarantine records to be maintained for two years. This includes quarantine completion dates, treatment types and doses, water quality data during quarantine, and health observation notes.

Health certifications. Imported koi need health certifications meeting NJDEP standards for notifiable disease screening, including KHV and SVCV.

Treatment documentation. Unlike some states that focus primarily on quarantine records, New Jersey DEP specifically requires treatment records to be maintained with the quarantine file. Any treatments administered during quarantine must be documented with dates, products, and doses.

KoiQuanta's NJDEP compliance module pre-configures all required documentation fields. The koi dealer software for New Jersey covers dealer management alongside compliance.

Mid-Atlantic Import Corridor Compliance

New Jersey's proximity to major Mid-Atlantic import infrastructure, including Newark Liberty International Airport for air-freighted koi, means NJ dealers frequently handle recently imported fish. The import compliance documentation for these fish must meet both federal USDA APHIS requirements and NJDEP state requirements simultaneously.

KoiQuanta's dual-compliance module covers both regulatory frameworks. The koi dealer import compliance guide covers the federal USDA requirements in detail.

Hobbyist Considerations in New Jersey

New Jersey koi hobbyists keeping fish for personal use in properly contained ponds generally don't need import permits. However, NJ DEP does require permit holders for certain commercial activities, and the line between serious hobbyist and small commercial operation can be blurry. If you're selling koi to other hobbyists, even informally, NJDEP permit requirements may apply.
