bsfman & food chain, thanks for the tips and ideas. I have been doing a fair amount of googling and you gave me something things I hadn't thought to look for, like information on fish diet & omegas. I wonder how the corn shortage will affect what fish farmers are feeding?

I will look into yellow perch, too. I know that wild perch do great in Oklahoma.

We had a brutally hot summer this year, and it had not even occurred to me that raising fish would not be a year round activity. I had to go to the mountains for the entire month of July because it was so hot here. Fish would certainly not have made it in the 100+ weather. Glad I found this forum!

Thanks,
Donna
