Tassal moving to natural pigment

A move that I'm sure will win more investors to Tassal's side.
Tassal just announced that the astaxanthin added in fish feed in the future will be derived from natural sources. I have read in an article before that synthetic astaxanthin actually costs more to make (even though the benefits for fish and humans are the same), so this wouldn't be an added cost if it is true.
