Other Gardening

Raising maggots in bottles for fish food: Ground-up wild fish are used to feed farm fish. It’s a pretty revolting cannibalistic concept. But as much as a third of all the fish taken from the sea goes towards this purpose, and it’s inefficient: it takes around three pounds of wild fish to produce one pound of farmed salmon. Fish meal prices are, naturally, rising rapidly as the number of fish in the sea dwindles. So Drew got to thinking: what is it that every fisherman in the world uses to lure fish with? Worms, or maggots. And what makes maggots? Flies – maggots are fly larvae. Drew starting wondering if maybe flies could become the basis for fish-food instead of fish. So he started a company, AgriProtein, to give it a shot. Today the business has “immense cages of flies” in Stellenbosch. After female flies lay eggs – up to 1,000 – they are hatched into larvae and given blood and guts from a nearby abattoir to feed off. In just a few days, they are plump and ready to be ground into meal for (much cheaper) fish food. Drew says they can barely keep pace with the demand from fish farms. “It’s a profitable business, helping save our seas,” he summed up. http://www.dailymaverick.co.za/article/2012-10-26-sustain-our-africa-from-maggots-to-marketing/#.UwftBmJdXOU
