is a critical time for your fish. Here in the South there is virtually no chance your fish will freeze. It is possible for them to suffocate in the summer when oxygen levels are low. Be sure to check your pond early in the morning, if you observe your fish at the surface gasping for air then it’s time to take action. You can add an aeration system, build another pond or thin out your fish population. If you don’t take action under these circumstances then Mother Nature will thin your fish population for you.
