Bill,
I used this guide last year when removing perch from the big pond before draining it, and then again to be doubly sure before putting them back. The illustrations and photos matched the vent appearances of the bulbous females and males that exuded milt. I sent all the males to Scott's pond.
So I sorted twice for both bluegill males and yellow perch females and hopefully I was 100 percent accurate.
There were a few perch that appeared to be males but did not exude milt. I sent those to Scott's pond to play it safe. Not sure if they were males that weren't mature yet or females that dropped their eggs early. Or perhaps sterile?
