Cecil,
I remember reading about a cement tank used in an aquadome to raise fish and the fish were beat up from contact with the, apparently not too smooth, walls of the tank. I guess the same is true in concrete raceways. This weekend I had an excavator in to dig a 40 foot long, 5 foot deep v shaped trench in which I'll build forms for a concrete wall to trap and deliver the spring into a pipe. If the flow is enough I may try tank culture outdoors, other than swimming pools what are some tank construction alternatives? I want to wait through at least 1 summer to see what the average flow is before I put in a tank. If nothing else, I'm succeeding in drying up a large muddy spot and condensing the flow into a manageable narrow stream flowing to my pond. I read the article about Tiger Trout in Pondboss but they're hard to come by. They would be better to grow out in my pond.
Didn't you say you had a copy of Small Scale Aquaculture? If so, there are some varations of tanks in there. Fiberglass tanks are available too. Do you have a copy of the Aquatic Ecosystems catalog? In there they sell steel circular tanks that you can set up on site or you can bury in the ground, and as one option pour concrete in the bottom with your drains in place. I have a good book on trout culture I can send you that covers this stuff if you promise to send it back when you are done. Email me your mailing address and I will send it to you. My email is in my profile.
