We have had a heavy overcast for a few days now and it killed my biggest bluecat. It was 19 1/2 pounds. Made me sick. I seined about ten that were eight to twelve pounders and put them in my barn. I guess if they look okay when the clouds are gone I'll put them back in. We finally got rain this morning. It seem to help the other fish, but we are forcasted to have clouds for a week. My other pets in the other pond have electricity so I put in a pump to splash. I think they will be okay.
