Actually, Tilapia seem to thrive in warm water. According to one source, they can withstand up to 107 degrees water temp. What you have to be concerned about is the water temp on your plant roots. Most plants go to seed when their roots reach a certain temp. I was growing Okra last summer and my water temps were in the high 90's and the Okra, sweet potato leaves, and Tilapia loved it.

Also, your system can be designed with tanks or pipes in the ground to help offset daytime temps.
