Yes they are taking over. I caught some nice ones this spring and summer in a place where I have never seen them or heard of them being there. I posted a few pics on the American Fisheries Black bass Society face book page and the Steve Sammons from that site contacted me( he is a Auburn Fisheries Scientist that I have fished with before) and he said the NCWRC wanted to talk to me about them. Steve gave them my info and one of the Biologist from the NCWRC called me and after talking he told me these were the First Alabama Spotted Bass from this area where I was fishing. Not good news. they out compete largemouths and take over and they hybridize with smallies and shoalies and wipe them out. Bass fishermen are spreading them.
