Talked to my fish guy the other day and he said I probably pumped in a herbicide and killed the plankton bloom in the pond and that caused a lack of oxygen. That why most of the bigger fish died and some lived. He said if it was a pesticide everything would have died.

On the bright side I will be getting more bass from him in august or Sept. Also put my trap out there and have trapped some baby coppernose bluegill. So not all is lost. The minnows are finally starting to eat feed again.
