didn't mean to start arguments here,,,just really need to know how doable this is before i turn him loose,,,,,,more of a hobby for him than a money maker.....not sure how much of a problem heating the water would be, he seems to be interested in tilapia, might be cause that's usually what I buy....I keep my ferment right inside the barn door and it does not freeze,,,only after putting it out for the birds does the problem start....so it might be doable to keep water temp inside the barn...
trout sound interesting only because the water temp could be lower,,,,but the only time I ate trout, I picked little bones out of it and it really was not that good,,,in defense of the trout, my sister in law cooked it and she ruins boiled water...
