Where you live, you're unlikely to see water temperatures over 20C. Perch would work well, though they don't grow as fast as some others. Trout would work well for you also. I grow them here in Wisconsin.

Probably the best advice, however, is to find and visit your local hatchery. Ask them what they'd recommend, and what their prices are. Consider buying 7-8" fish. They're not that expensive and you will grow them out much faster.
