I can see this doing well for those that have a small aquaponics home set up. A few bugs every now and then would be a great treat for your tilapia or pike.
Insects generally form a very important part of the food chain, so why not culture them and then transfer that protein up into a more palatable form.
Here is a useful excerpt from permaculture guru Bill Mollison.
Bill Mollison: "Yes, well sometimes you walk on the land and you have the crop. People say, “I’ve just bought some land I want to develop a crop.” I’ll give you and example. I had a young bulldozer operator in Australia. He’d just bought some really run-down cattle land. He had a bulldozer and he put some dams in. Then he said, “Will you come onto my farm and tell me what I ought to do here?” He had nice dams there which he had stocked with trout. ”How are they going?,” I asked him. ”Fine,” he said. ”I got some eight pounders out of them.” ”When did you put them in?,” I inquired. ”Last year,” he replied. And the place was swarming with grasshoppers; it was overgrazed.
I said, “You’ve got your crop; your crop is grasshoppers!” On a 1.8 to 1 conversion ratio you can get a pound of trout for every pound and a bit of grasshoppers. You can trawl those grasshoppers just like you trawl fish. So, the other thing is, grasshoppers go for yellow, so if you float yellow balloons on the dams, you get a rain of grasshoppers into the water. So that’s what he did, and he had his crop. The land might already have its crop on it, and yet you might want to change that crop, and you will come out worse off.
For instance, we have a pasture grub that runs at 20 ton to the acre living in the first four inches of the soil. If you covert it into turkey, you’re talking 5 ton of turkey to the acre, just for a small soil-skimming operation daily. But they’re still trying to get rid of the pasture grub! And yet that land can barely sustain a sheep on four or five acres. So where’s the trade off between a 120 tons of protein and 40 pounds of protein as sheep? So, wherever we see that the crop is already there we’ve come out on top. And we have nothing to do."
I also heard him say that anacondas have the highest protein conversion rate in the world, if you are looking for a more exciting crop.
