Skretting Australia & the ASC Feed Standard
When you see the ASC sustainability label on a seafood product, it means the seafood has been farmed according to the criteria of the robust ASC environmental and social standard. Skretting Australia is proud to play our role in supporting the presence of the ASC label across Australia and New Zealand.
Our ASC Journey
After years of preparation, Skretting Australia became the first Australian feed mill to be audited and certified against the ASC Feed Standard in 2025.
The Aquaculture Stewardship Council (ASC) is an impact-driven organisation working to accelerate the seafood farming industry's transition towards greater sustainability through world-leading certification and improvement programmes.
Achieving ASC Feed Standard certification demonstrates Skretting Australia's commitment to responsible feed production and enables us to support ASC-certified farmers across Australia. Beyond supporting certified aquaculture operations, the standard drives continual improvement throughout the feed supply chain by establishing robust environmental, social, and sourcing requirements.
While certification represents a significant milestone, maintaining certified status requires ongoing commitment. Through regular audits, performance monitoring, and continuous improvement initiatives, we work to uphold the requirements of the standard and contribute to a more responsible and transparent aquaculture industry.
ASC Feed Standard Overview
The ASC Feed Standard establishes requirements for responsible feed production across environmental, social, and supply chain performance. The standard is structured around five principles that address the key sustainability impacts associated with aquaculture feed manufacturing and raw material sourcing.
Principle 1: Legal, Social and Environmental Performance
Establishes the foundational requirements for feed mills, including legal compliance, management systems, worker welfare, health and safety, environmental management, resource efficiency, emissions, waste management, and stakeholder engagement.
Principle 2: Responsible Ingredient Sourcing
Requires feed manufacturers to implement due diligence systems that identify, assess, and manage environmental and social risks within ingredient supply chains. This includes supplier oversight, traceability, risk assessment, and corrective action processes.
Principle 3: Ingredient Accounting System and Eligible Ingredients
Defines requirements for ingredient traceability, mass balance accounting, chain of custody controls, and the use of eligible raw materials. This principle ensures that ingredients claimed under the standard can be accurately tracked and verified throughout the supply chain.
Principle 4: Responsible Marine Ingredient Sourcing
Addresses the sourcing of marine-derived ingredients such as fishmeal and fish oil. Requirements focus on legal and sustainable fisheries management, ecosystem protection, stock health, bycatch considerations, and social responsibility within marine supply chains.
Principle 5: Responsible Plant Ingredient Sourcing
Establishes requirements for terrestrial crop-based ingredients, including the management of environmental and social risks associated with agriculture. Key topics include land-use change, biodiversity protection, deforestation and conversion risk, labour rights, and responsible farming practices.
ASC Declarations and Data
As part of our ongoing compliance with the ASC Feed Standard, we are required to publish up-to-date information relating to specific ASC criteria. This includes details of our ingredients, their regions of origin, and associated risk assessment information. Much of the data reported here is also included in our annual Impact Report, and is reproduced here for ease of access.
