I have been fishing around Kansas this whole summer and noticed that most the channels I catch in Fort Riley have small red spots on their skin, others have spots of skin missing, mainly on their bellys, and a few of them have red spots throught the meat after skinning them. Does anyone know what this is and is it safe to eat them? Thank you. ETA: Some also have sunk in eyes or are missing an eye. In fact alot of them from one small lake are missing an eye.
