Dear Sir,
I have a commercial sized aquaponics system in Nicaragua Amigos for Christ | In His Service It is my strong opinion that Friendly Aquaponics is the best source for commercial training in the world. That is where I got my training. For further info. go to Friendly Aquaponics...
Two good sites to look at Morning Star Fishermen | Aquaculture an answer to Global Hunger in 3rd world countries. Educational Training Center in fishfarming and aquaculture.
Best of luck.
