The Aquaculture Stewardship Council was established in 2010 by the WWF (World Wildlife Fund) and Dutch Sustainable Initiative. It is an international non-profit organization working to increase the sustainability of both fisheries and farmed fish (aquaculture) worldwide.


The ASC mission is the work towards sustainable farming and social responsibility by utilizing efficient methods to create value in the entire feed to food value chain. The ASC standards cover parameters such as environment, ethical considerations, animal welfare, and economic conditions. It further covers all production types; recirculating aquaculture systems (RAS) and flow-through systems. Each species of fish has its own standard.

ASC and Aller Aqua

Fish feed produced at Aller Aqua is approved in terms of paragraph 5 in the ASC Freshwater Trout standard. It is also possible to be approved in terms of paragraph 4 in the ASC Salmon standard. These paragraphs concern environmentally efficient utilization of resources, including:

  • Traceability and transparency of raw materials in feed
  • Responsible origin of marine raw materials (including the use of wild fish for feed)
  • Dependency of wild-caught marine ingredients in feed (the source of the marine raw materials)
  • Responsible origin of non-marine raw materials in feed


Traceability and transparency in raw materials for feed

For documentation of specific requirements for traceability for feed ingredients, Aller Aqua has chosen the mass balance principle. Mass balance documents the amount of purchased raw materials with the amount of feed sold. In addition, we provide information about all raw materials which constitute more than 1% of the weight of the feed.

Responsible origin of marine raw materials

Requirements state that all fishmeal and fish oil used in feed stems from ISEAL accredited fisheries such as MSC and IFFO-RS certified processing. Recognizing that this is not a viable possibility a number of alternatives are provided. Aller Aqua has chosen Fish Source score, which is calculated for marine raw materials used in the feeds. This dispensation from 100% ISEAL-certification is temporary and awaits a new complete ASC-feed standard.

Dependency of wild-caught marine ingredients in feed

To determine our dependency ratio for marine raw materials we carry out a calculation that provides a number, which we can then monitor over time. Like other fish feed producers, we strive to reduce our dependency on marine raw materials and to find great alternatives to these valuable raw materials.

Responsible origin of non-marine raw materials in the feed

Aller Aqua has a documented responsible sourcing policy for feed ingredients.
This requires that 100% of all ingredients based on soy should be certified RTRS (Round Table on Responsible Soy Production).
