Temperate Perch - Classification

Classification

The temperate perches are closely related to the temperate basses of the Moronidae Family, and older literature treats the latter as a belonging to the Percichthyidae Family. Australian freshwater Percichthyids were once placed in the Serranidae (marine grouper) family, and the two families are considered to have some link to each other.

Around 22 species of Percichthyids are now recognised, grouped in around 11 genera. Most but not all are freshwater fishes. They are mainly found in Australasia and South America, though some (notably genus Siniperca) are native to Asia, and some of the marine species are found as far north in the Pacific as California.
