Something systemic seems to be at play.
Do you have water test results for ammonia, nitrite, nitrates and PH?
Is there any gardening-related substance that might have got into the pond before it froze over, either your own or possibly over a fence from a neighbour? I've read posts in the past where the pond has inadvertently ended up with a poisonous substance.
I don't have pond experience but hopefully someone who does will be able to help out.
