Seafood is considered the healthiest, because it's very rich in iodine and well-digestable proteins, plus fish is enormously good for industrial production because it is considerably more fertile than any animal species, even rabbits
The main point why fish is that fertile is that most fish species spawn several thousands of roe and that its spawn is independent from the parents from its very birth, plus most fish species are not fastidious about what food to consume.
So in order to have a school of several thousands of fish you only need a pool or a lake with optimal conditions for fish hatching and growth, fish food plus a bucket of live impregnated roe and several months of time!
My idea is starting my own small business by growing tons of delicious fish species this way, only first I should study biology well enough to create optimal conditions for fish growth, feeding and breeding and earn the initial stock. Any potential sponsors here?
