Fish Radio has reported on the global search for alternatives to wild fish as a food source for farmed fish, and how insects fit the bill.  Now that South Africa fly farming company we’ve touted called Agriprotein has just won a ‘food chain global champion’ award in Britain for its MagMeal – an ingredient used in fish and animal feeds made from flies reared on food wastes.

Every year a quarter of the world’s  fish catches – 20 million tons – is directed away from dinner plates  and instead goes  into fish meal, according to the U.N.’s Food and Agriculture Organization.

World fish growers are facing increased criticism to find other food sources.

Fish meal accounts for 60 to 70 percent of farmed fish production costs. It can take up to four pounds of wild fish meal to grow one pound of farmed salmon.

Tests prove that all kinds of insects can make a good feed but the high crude fat content in black soldier flies provides an extra nutritional boost.  AgriProtein uses food wastes to cultivate fly colonies and converts the larvae into MagMeal.

The company calls the U.S. the “world center” of  protein consumers and  organic wastes – a natural fit for its fly building business.

The company has plans to build 200 fly farms in the US and Canada  by 2027, Undercurrent News reports, supplying the $100 billion aqua-feed market.

Scientists from Idaho universities also are embracing the “waste to nutrient industry” with a maggot-based fish feed that also reduces billions of pounds of cow poop.

Idaho is the nation’s largest rainbow trout producer and the fourth biggest dairy state.

Flies feed on the manure and seed it with maggots; it is enriched with fish guts and turned into a feed that is being snapped up by the trout.
