Last summer I stocked my 2/3 acre pond with yellow perch, hybrid bluegill, and largemouth bass. It is 10-16 feet deep. All of the fish did well all summer. I aerated all winter. This spring I am finding a lot of dead fish. The fingerling bass I planted are now 10" plus fish that are floating up now and then and look to have been dead for a long time. My bluegill are around 5" or so and are dying now. I find a couple every day or so and some of them are even still partly alive. There are some red sores on the sides of some of them that are faint. I have no idea how the perch are as we rarely ever saw them anyway.

I have pulled out dead fish that total about 10% of the stocked rate.

Where do I start? This pond is my baby and it is terrible to just watch the fish die.
