The blue tilapia hybrids do not tolerate as cold of water as the pure blue tilapia. If your pond ever gets any ice cover the blue hybrids will definitely not survive your winter conditions. All you have to do is periodically as in every two weeks this winter check your pond water temperature this winter. If it drops below 48F the hybrid blues are dead. Checking periodically all winter gives you a good idea how much lower the water temperature gets this winter. I am predicting your pond water will be in the 39-40F range as its low temperature. Report back and give us your low water temp measurement. We will see how far I miss the 'mark'.
Will do. It was around 64 degrees last week but this cold snap we've had must have dropped it down a bit. I haven't checked it since. [EDIT] Checked it after cold snap and it's down to 55 degrees.
My other concern with his fish are he said they will average 5 to a pound. How many do you think I should put in to keep them from being an expensive snack?
