They're dark due to living in shallow water, no sign of bedding. Only a handful were female and they didn't look close. This area is a huge shallow flat. The fish had move to narrow areas along the edges where there was some shade from the trees on the bank. I moved along the edge casting into the shade, mostly in 12 to 18" of water. The fish seemed to be feeding heavily in the afternoon as the water warmed. I also caught numerous stripe, bass and catfish.
