Yeah; when we had them on the stringer they were turning darker, that's only normal. I always look at the anal area and usually the more swollen and red is normally a female? Stink cleaned them and can reply to this for more accuracy. I've been fishing crappie on the big-E for 35 years and believe me you will catch them shallow LATE, in what the old timers refered to as the "False Spawn".
