Pond Boss Forums AERATION Should I aerate? Winter 100 % fish kill - aeration?

2" snow and 2" of cloudy ice will stop all sunlight and plants under the ice will die, then decompose, creating even more of a draw on the O2 reserves. Most plants that grow underwater during the summer don't live during the winter, just like plants on land.....

3' water depth doesn't leave you with many options, you probably had 100% of the fish biomass in less than 30% of the pond. If the water drops that low again, I'd expect a significant winterkill even with aeration. Harvest during the year is a very vital part of pond management, especially if you are going into winter with less than full pool. In my personal pond when we had a drought I made sure to harvest over 100# of fish before the winter to lower the O2 demand from the fish.
