Very few species of fish require live food, in order to become conditioned to breed, typically just those that strictly eat live in captivity.BTW, you veggie-only types: thank yer lucky stars that humans don't have to consume live food to breed.
This is common among the few fish I have bred.
I've lost count how many animals I have killed, cleaned, butchered, and eaten. From thousands of fish, to elk and moose. Not for blood lust, I was putting food on the table when times were lean. Nowadays I just make a trip to the grocery store, and I have given up fishing for sport. I don't eat lobster, so that's a non issue for me.
