Read: Breakthrough in omega-3 understanding could revolutionize feed industry, by Nicki Holmyard in SeafoodSource (31.05.2018): https://www.seafoodsource.com/features/breakthrough-in-omega-3-understanding-could-revolutionize-feed-industry
“… an international team of scientists from the United Kingdom, Portugal, Spain, Japan, and Australia found that omega-3s can be created by many marine invertebrates.”
“Our study provides a paradigm shift in understanding, as it demonstrates that a large variety of invertebrate animals, including corals, rotifers, molluscs, polychaetes and crustaceans, possess enzymes called ‘desaturases’ of a type that enable them to produce omega-3, an ability thought previously to exist almost exclusively in marine microbes,” [said lead scientist Oscar Monroig from the university’s Institute of Aquaculture].
