Will post pics of sexing yp by urogenitile openings when I get more time. Need to get something done today. LOL

I will say there is nothing as accurate as probing for eggs or the appearance of milt. I'm convinved there are fish that are a atypical in urogenitial appearance and by itself it will never be 100 percent.

A couple years ago I religiously culled out 20 large yellow perch from a holding pond out of 100 that appeared to be textbook females and planted them in an all female yellow perch pond. Next year I did have some reproduction in that pond. Either one fish that escaped when sorting a cage was a male or at least one of those twenty fish was a male.

I no longer sex fish during times of year they are not in spawning mode by urogenital opening, nor do I raise fish in cages in the monosex pond!

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
