temperate bass families The *Moronidae* are a family of perciform fishes, commonly called the temperate basses, consisting of at least six freshwater, brackish water, and marine species. The members of this family are most commonly found near the coastal regions of eastern North America (including the Gulf of Mexico), northern Africa, and Europe. The family includes the genera *Morone* and *Dicentrarchus*. [https://en.wikipedia.org/wiki/Moronidae] The members of the family *Percichthyidae* are known as the temperate perches. They belong to the order Perciformes, the perch-like fishes. Almost 40 species of percichthyids are now recognised, grouped in 10 genera. Most but not all are exclusively freshwater fishes. They are mainly found in Australia, but species are also found in southern South America (Percichthys) and eastern Asia (Coreoperca and Siniperca).
