DonoBBD, I think you have a perch and GSH heavy pond like mine with few predators. Our water quality and make up might be quite different though. Do you have much problem with FA?
I had a few years with heavier FA, stocked Tilapia assuming it would always be that way, but last year, no tilapia and very little FA, and this year none at all.
I don't do anything special, run the aerator 12 hours a day, try to keep fertilizer out but my fert people do broadcast granules and I'm sure some gets into the pond.
My FA problems have gone away now that I have been aerating at night. 8pm to 8am keeps my pond much much cooler than 24/7. Running the air 24/7 I had water temps in a low 80's.
So the surface gets warm but only the top 10-30"s depending on the day and wave action.
I have only used two quarts of blue dye this year.
Yes yellow perch only with a few walleye and common shiners, few emerald shiners. One pain in the ass mink.
Cheers Don.
