I am going to experiment with this. I got some of Rex's Tilapia this year and they are doing very well. Probably over 500 between 2-4" swimming around in 1/2 acre pond. Started with 17 that averaged 3/4lb. My plan is to get a 150 gal plastic tank and a good air pump and a couple of 10" air stones on the bottom. Will be in the basement with constant cool temp of around 62 degrees. I plan on putting around 60 3" Tilapia in around mid-October. I'll feed pellets and occasionally rotate in some fresh water and mabe a complete cleaning half way through. I'm in Ohio so should be able to re-stock in late April-early May. I figure the cool water temp will keep them from growing fast. Any input/advice on this project will be appreciated. Thanks Jeff
