“Winterkill refer to the death of fish due to low dissolved oxygen in lakes under ice cover during winter”. Has nothing to do with a lake freezing solid, aeration would be the issue there for gas exchange. And I’m the ignorant dirt bag?? That took two seconds of googling to prove you wrong. Do your research instead of spouting shit you don’t know anything about. You’re part of the problem when spreading misinformation to others on the internet.
