I am located in NE OH and considering stocking some Talapia in my pond this season. We have had a warmer than normal Spring so far and the pond is active, alive and well. I am already seeing some FA bloom and was wondering how soon I can safely stock Talapia without risk of them dying off due to the water temp not being warm enough. I don't know my water temp... I have not measured the water temp yet, but I certainly can take a few measurements to see where it is prior to stocking. The fish farm says they raise them in 75F water so how much of a difference in temp can they tolerate?
