Pond Boss Forums MANAGING AN EXISTING POND Feeding Yellow Perch in-pond feed training

This is true but postitive phototaxic is only true for yellow perch less than 1" long. Older perch are neutral phototaxic to light. I suspect your underwater light attracted zooplankton which attracted small fish, which attracted the perch. Eventually the perch tried tasting some sinking-moving pellets and found them acceptable. Regardless it was a creative way to feed train some larger perch.
