I plan on building my system with a 290 gallon IBC (or something larger if I can find it cheap enough) in a greenhouse, and I'm thinking of using local fish species for my year round stock so I will only have to do minimal heating of the water for times when it gets really cold.

Since I'm in the mountains of Western NC, some of my main local fish are rainbow/brown/brook trout. According to wikipedia, Brook Trout like a wide range of water temperatures from 34 deg. F to 74 deg. F; it sounds like it would make an ideal fish for year round keeping.

Has anyone else tried raising trout in a FT that size? I'd kind of like to add a few every year so in 2-3 years I'd be able to have a few trout dinners every year.
