Does anybody breed anything as a food source for their larger fish?

[Heymikki]

So I’ve starting a bin of red worms and it’s got me thinking of all other crazy ideas to create a good food source for my larger fish. I’ve been considering the idea of breeding shrimp or crayfish as a food source for the larger fish. Does anybody do this?

Just white worms and daphnia, (daphnia indoors and outdoors) and mosquito larvae in season.

I culture superworms and dubia roaches, primarily to feed reptiles and amphibians. However, some of my larger fish like them too.
