Ken, I am not sure there is a scientifically recognized subspecies in our migratory coastal YP. However, there is no doubt in my mind there is significant genetic adaptations compared to perch found in the Midwest, etc. I doubt a YP brought to the coastal rivers of VA would do very well. Find any deep hole in a larger coastal river and its tributaries from mid February into early March and drop a shiner in it and you will find all the buck perch you can catch. If you are lucky, you may get into a school of roe perch.
