avasata, Thanks for the tip, thats good to know.

ewest, Thanks for the links, I have read those aswell. The Data table is what I'd like you to reveiw when you have the time. The goal is a predetor /prey stocking ratio, but i realize few have probably done this before, so they may not want to express an opinion, but ya'll have ALOT more knowledge than me so any suggestions that hold water would be greatly appreciated.As for Tilapia, I'm chosing Blue because they can tolerate colder temps (just in case). And they are found naturally in our resaca (ponds) system.
