Welcome to the forum.
It's strange you would mention raising edible fish, I just finished my "Crayfish in Aquaponics Guide Book" and was going to do one on Greenhouses, but decided about 10 hours ago to do one on "Edible Fish in Aquaponics Guide Book" instead.So why I am here in this forum, to learn as much I can about raising fish.
It will take me about 3 to 4 weeks to do all the research and put it all together. Hope you can be patient enough to hang around until the release.
