Caught this guy near a manmade dam this morning. Fought hard the whole way to the yak when I got him in my hands I noticed the lack of bottom cartilage between his lower jaw and tongue area. Also noticed a discolored tongue and a white spot midway along his right side. Any ideas what this could be? The body of water is fed by a river to the north and I have caught very large bass there pretty frequently. There is also a large carp population there throughout the year. Any tips would be great. Thank you!
