Lake Harney (Geneva, FL) area and Mullet Lake Park area St. Johns River. Take a look at the pictures and reply which catfish you think this would be. To my knowledge we have Channel Cats, Butter Cats (Yellow Bullhead) , Brown Bullheads. Also in the River there is White Catfish but not one I am familiar with...I don't think so anyway. So please chime in and let me know what you think.
