J.W. Thanks again for info on cornmeal, called local grain store and they said will sell for $5 50# bag, big diff from texas. And no I don't have to replace fish, just like to buy couple hundred dollars worth fatheads each year from fish farm that comes to local feed store. I have fenced off a 10'x10' area approx 2' deep with 1/4 in. plastic mesh to try and raise own fatheads, seems to be working as ice melted off completely yesterday and there is minnows all over this area. And yes I am going to experiment with the tilipia this spring too.
