The ASC farm standards set strict requirements for responsible aquaculture for different aquatic organisms that encourage seafood producers to minimize the key environmental and social impacts of aquaculture. The ASC standards are based on best practices and sound science. 

ASC Feed
ASC Feed Standard will be the first Standard to take into consideration the impacts created across all key ingredient groups and across the entire ingredient supply chain (feed mills & suppliers). Includes all major agriculture crops such as wheat, corn and canola, in addition to soy and palm oil, and marine ingredients.

The ASC Feed Standard became effective in January 2023 and feed mills are now applying for certification. ASC certified farms have until January 2025 to transition to ASC compliant feed produced under the ASC Feed Standard to continue to meet the ASC Farm Standards.

The following list of documents are separated by Farm and Feed: Documents 1 through 16 are for ASC Farms and from 17 through 19 are for ASC Feed.
