I have to have females and males I would think, I have added over 200 YP to the pond over a three year period. I will admit I have never caught a male with milt coming out of it, but I have caught a lot of really fat females. I have never seen a perch minnow either.

I am now transferring some perch from my neighbors overcrowded YP only pond in exchange for some LMB from my pond. I will have YP spawning eventually.
