MSC is an international certificate for sustainably caught wild fish from the Marine Stewardship Council, an international independent organization to protect marine life. Products with the MSC quality mark are guaranteed traceable to sustainable fisheries that meet the MSC fishing standard. This means that 1. there is no overfishing on fish stocks (fishing pressure and biomass are healthy) 2. there is respect for other marine life (such as birds, mammals, sensitive areas) and 3. good management takes place (catch agreements, compliance, check).

ASC sets specific requirements for salmon farming, such as antibiotic use, fish feed, biodiversity protection, greenhouse gases, waste management and chemicals. Specific attention is paid to risks in the salmon chain, such as the risk of fish escaping and the prevention of diseases and parasites. Requirements are also set for suppliers of young salmon. ASC also monitors working conditions and dealing with local communities. The requirements that ASC sets for salmon growth - water quality, animal health and living space - have a positive effect on animal welfare.
