AQUACULTURE articles - Hakai Magazine and The Atlantic: What It Takes to Feed Billions of Farmed Fish Every Day - They’re usually just given ground-up fish. One company is exploring a more sustainable alternative: maggots.

excerpt:

As Vickerson has learned, black soldier flies can be farmed extremely efficiently. Enterra pioneered and patented some of these techniques. But at the heart of their operation is a very low-maintenance livestock. You don’t have to hunt, fish, or grow anything to feed black soldier flies. They don’t require fresh water. As larvae, they’re happy eating all manner of food waste that would have ordinarily gone to compost or the dump. Black soldier fly grubs, Vickerson explains, can recycle those nutrients back into the food chain because, unlike many other insects, they can consume a wide variety of foods. In the larval stage, they’re packed with protein and are high in fat, including the omega fatty acids highly prized by the aquaculture industry and consumers alike. Native to the Americas, black soldier flies now range throughout the warmer parts of the world, although they don’t naturally occur in Canada.

This line in that article caught my eye: “Norway, at any given time, there are about 400m farmed fish and only 500,000 wild fish.” If they can raise so many fish in farms, why can’t the same techniques be used to re-introduce Atlantic salmon to their native habitats, in north-eastern North America, for example?

Thank you for the informative title instead of “You won’t believe what’s in farmed fish feed!!”
