Temperate Bass Family- 
              Percichthyidae 
  Two species of temperate basses in one genus are known from Wis- 
consin; both are strictly freshwater species. In the United States and 
Canada the temperate basses consist of seven species in four genera 
(Robins et al. 1980). Five species are essentially marine; two, the white
perch and striped bass, run up coastal streams to spawn. Gosline (1966) 
has separated the temperate basses from the sea basses (Serranidae). 
  The percichthyids are deep-bodied, percoid fishes with well-devel- 
oped jaws armed with numerous teeth. Their upper jaws are bordered 
by the premaxillaries, with the maxillaries expanded posteriorly. They 
have seven branchiostegal rays, and the pelvic fins are in a thoracic po-
sition without an axillary process. 
  Although superficially resembling the black basses and sunfishes, the 
temperate basses are not closely related to them, and differ from them in
a number of characteristics: temperate basses are random spawners and 
they do not build nests or care for their eggs and young, as do most 
members of the sunfish family.
