I might as well go for broke and shoot for the moon:
A local hatchery that could, and would, accurately sex their fish and gladly sell me all male BG, and all female YP.
No need to have them sex yellow perch if you get them in the early spring. You can easily sex yourself. Same goes for bluegills if you get them large enough. It's it's too early in the year to sex the bluegills put them in a cage until mid May or so. Then it's easy to sex them.
That's true, and I usually have a couple spare cages I could use for native BG. However, I wouldn't know one end from the other on a YP..
After I learn to differentiate them, what would I do with the males? I only want perch in one pond.
