Omega-3: The Ultimate Circular Crop?
Traditionally big-farmed fish like salmon obtain their necessary omega-3 through consuming fish meal made of small oily fish, like anchovies. These small fish are wild caught, accounting for around 20% of all wild fishing — the majority of which could be eaten by people directly. And so, fish farming like this puts great strain on global stocks of these smaller fish.
MiAlgae is a company based in Edinburgh, Scotland that cultivates microalgae in 30,000-liter fermenters to be used in dried form, primarily for fish and pet food. What the company has essentially said is, “What if we can cut out the small fish and feed farmed fish algae, the thing that actually produces the omega-3 directly?”
