Thanks for the Spencer Jack tip actually never even crossed our minds to check wit him. We do grow earth worms she is thinking of expanding her setup. It gets tough to keep up with 4000 fish sometimes not all adults but all ages.
4000 fish, well... err... that's a lot. I see now why you guys need bulk fish food. Maybe also grow some duckweed, it can be processed to a cheap, renewable, infinite fish food. I heard reports that in some fish farming industries duckweed are used for fishfood, not to mention aquaponics as well.
I'd avoid raising bloodworms unless you can guarantee they're to remain in a completely sealed culturing vessel. Bloodworms are larvae of the midge fly. It would be unnerving having mosquito looking midge flies loose all over the place.
I think crickets should be dropped, they're demanding... cultured Cockroaches can be a better alternative... Also they're more prolific than crickets. But as Oddball said below it should be contained in a enclosed container, if not it may cause invasion in your ecosystem and also in your house.
+1 they can slip out and thrive in other water bodies...
it depends how unnerving the OP would find it, it could be a good thing as then they will breed in all bodies of water, providing food.
If raising duckweed you can also culture amphipods (Gammarus) shrimp. These little side-swimmers are prolific dentrivores that will consume anything missed by your fish and provide free food for small to large fish.
Being in Canada, you'd have an easy time culturing daphnia.These cool weather shrimp will provide food for fry to small adult fish species. Hatchery supply companies sell grading sieves so you can separate newly hatced shrimp for fry from adult shrimp for larger fish.

Really ought to think before posting. With nearly 100 tanks to feed, growing enough bloodworms while maintaining a rotational crop would mean having to bear upwards of a 100,000 adult flies buzzing around the fish room. Even if they are non-biting, having swarms of these flys buzzing in your ears, flying into your eyes, and flying into every inhaled breath would render a person insane.
I think culturing blackworms, trout worms,nightcrawlers and brine shrimp might be an easier alternative. Also I've had problems with my fish getting intestinal parasites and infections when feed bloodworms regularly.
