Pond Boss Forums INTRO Questions & Observations Slow Fish Kill

Chunks missing could be turtle bites after the fish died, walleye won't take chunks out like a shark or wahoo. Seems that most of the fish in the pond are smaller, and a GBH (Great Blue Heron) would eat them vs. just stab them and leave them like they do with larger fish.

I wouldn't add any more fish to the pond, your pond will be VERY fish heavy once they start reproducing. When you put the aeration system in, what was your start up procedure? Can you go out in the pond and take a temperature reading from different depths? If you go swimming out in it, is there a big temp change below 7-8 foot water depth?
