Sources: 5. Developments: 2. Brazil has introduced new regulatory frameworks for environmental licensing, including the General Environmental Licensing Law (Law No. 15.190/2025) which established general norms and analysis deadlines across various government levels. In conjunction with these broader laws, the National Council of the Environment (Conama) issued Resolution 517/2026 to update licensing specifically for the aquaculture sector, replacing the 2009 regulations. This update shifts the classification of aquaculture enterprises—covering fish, crustaceans, and mollusks—from area-based criteria to annual production volume. Under this new system, small-scale operations may use the self-declaratory License by Adhesion and Commitment (LAC), medium-scale enterprises will follow the Single Environmental License (LAU), and large-scale operations will continue with ordinary licensing processes. While the cultivation of non-native or hybrid species does not automatically change the licensing modality, mandatory biosecurity and escape prevention measures remain required. The aquaculture-specific rules are set to take effect in April 2027. ## Timeline ### 2026-10-19: Brazil implements new environmental licensing laws Brazil implements the General Environmental Licensing Law and introduces new aquaculture regulations based on production volume, effective for various sectors through 2026 and 2027. 3 sources. https://clstr.news/cluster/brazil-implements-new-environmental-licensing-laws ### 2026-10-17: Brazil updates aquaculture environmental licensing rules Brazil has updated its aquaculture environmental licensing rules via Resolution 517/2026, scaling requirements based on annual production volume to ensure proportionality. 2 sources. https://clstr.news/cluster/brazil-updates-aquaculture-environmental-licensing-rules --- Cite as: Brazil aquaculture environmental licensing updates.
