I can't say if they were truly "blue perch" I caught, but I have seen many similar colors of YP come from waters here in PA, lakes in Ontario and as far north as Chibougamau, Quebec it doesn't surprise me. I have often seen younger fish that exhibited that light coloring, I always thought it was partly due to environment or some fish getting more sun shine than others, seriously, minnows in a white bucket will bleach their colors and be lighter than those kept in darkness, stands to reason a fish that spent more time shallow would do the same.
