The salmon industry uses approximately 40% of the world’s available EPA and DHA, with the oth- er aquaculture industries using 35% and the human nutrition industry the remainder. Owing to the fi- nite nature of these fatty acids, the salmon industry has had to reduce its use in order to maintain suffi- cient supplies to enable the industry to keep grow- ing and keep up with the strong consumer demand for salmon. However, this has led to a 50% decline in the levels of omega-3 EPA and DHA in salmon fillets, whether of Norwegian, Scottish, Chilean or Tasmanian origin. This reduction in the nutritional value of salmon is a key concern for the value chain. Consumers purchase salmon for several reasons, but it is mainly the healthy omega-3 content that it pro- vides that is the key motivation. Finding alternative sources of these precious omega-3 resources is there- fore a top priority for aquaculture in general and the salmon industry in particular. At the beginning of the interview, you stated that the industry must adopt new technologies and practices to deal with the sustainability problems it face. As DSM, you have a natural marine algae -based solution that you have developed with Evonik. Could you give us information about this new technology product? How does this solution contribute to the industry?
