Surfsteve, the book Cecil suggested utilizes upground pools. I also highly suggest you get VanGroder's book. It can often be found on used book sites.
Brand new it's only $25.00. It's a steal for the wealth of information it has. Not difficult to read either like some aquaculture books.
If anyone knows of a place to buy this book that isn't broken (charging from $100-$2500 for this paper back) I would greatly appreciate it. It seems that amazon.com price adjustment bots have inflated the price of this book for every online book store that I found stocking it.
