Yep-freshwater drum commonly called a perch here on the Mississippi River .if you split the head open there are 2 stones right behind the eyes and one will have a L on it,it's called a lucky stone( obviously not for the perch) On that size fish it will be about the size of a dime , my Gramps had some he always carried on him that were the size of a half dollar.
