Aquaculture Stewardship Council standards

Demonstrate your commitment to responsible aquaculture farming.

The Aquaculture Stewardship Council (ASC) standards for responsibly farmed seafood enable you to demonstrate to consumers that the seafood has been farmed in a way that minimizes or eliminates social and environmental impact of aquaculture farming. Certification according to ASC standards will qualify you to use the eco-label on products.  

The standards for responsible farming are managed by the Aquaculture Stewardship Council, whose mission is to achieve environmentally sustainable and socially responsible practices in the aquaculture sector using efficient market mechanisms that create value across the chain. 

What are the ASC standards? 

There are currently eleven ASC standards covering 17 species groups [abalone; bivalves (clams, mussels, oyster, scallop); flatfish; freshwater trout; pangasius; salmon; seabass, seabream, meagre; seriola and cobia; shrimp; tilapia; tropical marine finfish]. There is also a joint ASC-MSC (Marine Stewardship Council) standard for seaweed. 

To be certified to the ASC standard, farmers must comply with a set of requirements covering: 

  • Planning  
  • Development 
  • Operation of aquaculture production systems.

The standard focuses on production and its immediate inputs, with requirements that build upon best practices. It aims to be a starting point for continuous improvement and is therefore periodically updated to reflect the best available scientific knowledge, management practices and technologies.  

Meeting the full suite of requirements will require farms to: 

  • Have a high level of transparency and regular monitoring of key indicators  
  • Make some performance data publicly available  
  • Make other performance data available to the ASC 

To carry the ASC eco-label, the integrity of products originating in an ASC-certified farm is verified through the Chain of Custody (CoC) certification. For ASC, Chain of Custody is certified through application of the MSC Chain of Custody system, using ASC-specific requirements.  

Benefits of becoming certified 

Certification to the ASC standards gives producers several benefits:  

  • Access to markets with requirement for ASC certified seafood 
  • Clear and credible communication on responsible farming to customers and stakeholders 
  • Eligibility for products to carry the ASC eco-label  
  • Structured stakeholder involvement  
  • Independent verification of environmental and social best practice 

Getting started

The first step is to get more information on the certification scheme and become familiar with the ASC standard. The standard is available for download from the ASC website. 

Use the ASC pre-audit checklist as a tool to make sure you meet data collection requirements prior to the first audit. Some indicators require data to be collected at least 6 months prior to the first audit. 

DNV is an accredited third-party certification body for the MSC Chain of Custody standard as well and can support you with certification to this standard.   

Our experts are among the most experienced auditors in the industry, and we can provide certification to the ASC standard for your farm site.
