🐟Smallmouth bass

Micropterus dolomieu Lacepède, 1802

The smallmouth bass is a species of freshwater fish in the sunfish family (Centrarchidae) of the order Centrarchiformes. It is the type species of its genus Micropterus, and is a popular game fish sought by anglers throughout the temperate zones of North America, and has been spread by stocking —as well as illegal introductions—to many cool-water tributaries and lakes in Canada and more so introduced in the United States. The maximum recorded size is approximately 27 inches (69 cm) and 12 pounds (5.4 kg).
