How do Perca flavescens physical structures differ from walleye or sauger?
Answer
Absence of large canine teeth
A practical method for fisheries managers and anglers to differentiate *Perca flavescens* from other members of the Percidae family, such as the walleye or sauger, involves examining dental structure. Yellow Perch specifically lack the presence of large canine teeth, which are characteristic features in the dental structure of walleye and sauger. While body shapes can be similar, the dental structure provides a concrete physical differentiation. Furthermore, *Perca flavescens* is confined to the genus *Perca*, whereas walleye and sauger belong to the genus *Sander*.
