I have a small pond in my backyard. As the ice started to melt, I noticed a few small bass and sunfish that were dead. When it all melted, I found dozens more dead, including the 3 largest bass and one of the largest bluegills in the pond. Probably low oxygen levels.
depending where you are located and how much winter you had , it may have just been winter time stress . to have fish kill from low oxygen levels we have to have a much harder winter then we did here in Ohio . also if it was a oxygen issue i think you would have seen a lot more fish dead then you did
If we are planning to add White Amurs is that something we should do next month? I remember watching your video that said do it early spring while predator fish are still dormant?
Will keeping the air stones at the bottom of the pond in cold climates cause the pond water to “supercool” thereby causing the fish blood to thicken and and cause a winter fish kill? I have heard that aerators should not be left in deep water during really cold weather. That they should be moved up to only 3’-4’ deep. What is hour opinion?
don't see a problem with supercooling the water, first i only recommend at the most three stones per acre and use a 5 CFM pump. with this set up you can't move enough water to cause supercooling . plus i don't buy into the supercooling theory because there are ponds that are only 5 and 6 feet deep , the water temps will be about the same top to bottom in those ponds and the fish do just fine .
Thanks for the video. I put in a windmill bottom aerator to try to get rid of alot of these problems.

How often should I run aerator in winter and in summer? Is it the same all year long or what would you recommend for length of time?

we sell 11'' average size so loss from predator fish should not be a problem anytime
