Hello.
When I approach the pond the Yellow perch come to me and I often seen small perch (fry) swim past them without them touching them, but if I put minnows the same size they chase after them.
Have you ever observed this.
From the research I made they said yes, fish can recognize their own species (sight, smell, chemical signals) and avoid them if there are other species to eat, but this behaviour isn't absolute if there a lack of food cannibalism occurs.

Lots of data that fish can recognize their own young as noted. Also other species are recognized via same senses.

I recall seeing somewhere (undoubtedly either PBMag or InFisherman) where male BG recognize their own fry and only eat other males offspring.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
