Japanese seafood company Nissui Corporation has released its TNFD Report 2025, outlining how the group evaluates nature-related risks, environmental impacts and biodiversity dependencies across its seafood operations.
The report was published on 9 March 2026 and follows the framework developed by Taskforce on Nature-related Financial Disclosures.
It expands the company’s earlier TNFD disclosure first issued in 2023.
The document focuses heavily on aquaculture activities, particularly salmon farming operations in Chile, which the company identifies as a key growth area.
Expanded analysis across the aquaculture value chain
The 2025 report broadens the scope of analysis across the full aquaculture supply chain.
This includes feed production, freshwater aquaculture, marine farming operations and seafood processing activities.
The company said the assessment follows the LEAP approach, a methodology used within the TNFD framework to identify nature-related dependencies, environmental impacts, and potential business risks.
The analysis covers upstream and downstream activities within the aquaculture value chain.
Site-level environmental assessments
The report also introduces more detailed site-level assessments.
These include reviews of ecosystems surrounding salmon farming locations in Chile, identification of relevant biomes, and environmental interviews conducted at operating sites.
According to the company, this approach combines broad “bird’s-eye” analysis with detailed local assessments to better understand biodiversity impacts and operational risks.
Sector metrics and verification improvements
To strengthen the reliability of its analysis, the report references environmental assessments and certification records linked to the standards of the Aquaculture Stewardship Council.
These sources were cross-checked with site interviews to improve verification of environmental assessments.
The company also introduced aquaculture-specific disclosure metrics alongside TNFD’s global reporting indicators.
Sustainability strategy linked to marine ecosystems
The company states that protection of marine ecosystems and biodiversity is a central element of its sustainability strategy.
Within its corporate sustainability framework, the group identifies marine biodiversity as a key management issue tied to long-term seafood production.
Natural capital, including ocean ecosystems, is considered fundamental to its seafood and aquaculture businesses.
The company said it will continue expanding disclosure and stakeholder dialogue while implementing measures to manage nature-related risks identified in the report.
