Aquaculture Stewardship Farm Standard (ASC)
Ensure environmental and social best practices in fish farming
Enable sustainable aquaculture processes with ASC certification
Developed in line with industry best practice and with input from NGOs, scientists, retailers and producers, the ASC now has nine standards covering 12 species including salmon, trout, shrimp, bivalves, and tilapia. Each standard is specific to the species, but all seek to review the management of fish health, environmental impact, and social responsibility. As it rapidly becomes a requirement for those supplying fish to larger retailers, ASC certification can bring producers significant commercial benefits.

What is ASC certification?
The Aquaculture Stewardship Council (ASC) certification is a globally recognised standard for responsibly farmed seafood. It ensures that aquaculture operations adhere to stringent environmental and social criteria, providing assurance to consumers, retailers and businesses that seafood products are sourced sustainably.
What are the benefits of ASC certification?
ASC certification offers several advantages, including:
- Market access – Certified products are preferred by major retailers and food service providers that prioritise sustainability.
- Consumer trust – The ASC label is recognised globally, indicating a commitment to responsible aquaculture practices.
- Improved operational practices – Certification encourages aquaculture farms to adopt environmentally friendly and socially responsible methods.
What is the process for obtaining ASC certification?
The ASC certification process involves several key steps:
- Preparation – The aquaculture operation aligns its practices with ASC standards, addressing areas such as environmental impact, social responsibility and fish welfare.
- Application – The business applies for certification through an accredited certification body.
- Audit and evaluation – A thorough assessment of the operation’s compliance with ASC standards is conducted, including site visits and stakeholder consultations.
- Certification and ongoing compliance – Once approved, certification is granted, with regular audits to verify continued compliance.
How much does ASC certification cost?
The cost of ASC certification varies depending on factors such as the size and complexity of the operation. While specific costs cannot be provided upfront, LRQA can offer a tailored quote based on your organisation’s needs.
How long does it take to become ASC certified?
The timeframe for obtaining ASC certification varies based on factors such as the preparation of the aquaculture farm, the availability of certification bodies and the complexity of the audit. These factors can influence the duration of the certification process.
What does the new ASC combined standard mean for currently certified organisations?
Organisations already holding ASC certification will need to transition to the new combined standard once it is officially released. The ASC is expected to outline a transition timeline, providing a grace period for certified entities to align their practices with the updated requirements. This transition will involve retiring the existing species-specific standards and certified organisations will be required to adapt to the unified criteria. Specific dates and guidelines will be communicated by the ASC to ensure a smooth and efficient transition process.
What is the ASC combined standard anticipated for release in May 2025?
The ASC is planning to introduce a combined standard, tentatively scheduled for release in May 2025. This new standard aims to integrate various species-specific standards into a single, harmonised framework. The objective is to streamline certification processes, reduce complexity and ensure consistency across different aquaculture operations. By consolidating the standards, the ASC seeks to make it more straightforward for producers to understand and implement the requirements, thereby promoting broader adoption of responsible aquaculture practices.
ASC-certified seafood is used by globally recognised brands and retailers, including:
Walmart – A leading global retailer that prioritises sustainability in its seafood sourcing.
Whole Foods Market – A supermarket chain known for its commitment to high-quality, sustainably sourced products.
These brands rely on ASC certification to ensure they meet consumer demand for responsibly sourced seafood.
