The brook trout is a species of freshwater fish in the char genus Salvelinus of the salmon family Salmonidae. It is native to Eastern North America in the United States and Canada, but has been introduced elsewhere in North America, as well as to Iceland, Europe, and Asia. In parts of its range, it is also known as the eastern brook trout, speckled trout, brook charr, squaretail, brookie or mud trout, among others. A potamodromous population in Lake Superior, is known as coaster trout or, simply, as coasters. Anadromous populations which are found in coastal rivers from Long Island to Hudson Bay are sometimes referred to as salters. The brook trout is the state fish of nine U.S. states: Michigan, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Vermont, Virginia, and West Virginia, and the Provincial Fish of Nova Scotia in Canada.

Salvelinus is a genus of salmonid fish often called char or charr; some species are called "trout". Salvelinus is a member of the subfamily Salmoninae within the family Salmonidae. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea.

The bluegill bully is a fish in the family Eleotridae that is endemic to New Zealand. It lives in shallow, fast-flowing riffles and torrents, where it forages and shelters amongst the gravels. It has a similar distribution to the other endemic riffle specialist, the torrentfish. It can be found up to 100 kilometres (62 mi) inland, and from sea level up to an elevation of 480 metres (1,570 ft). The bluegill bully is the smallest of the Eleotrids, commonly reaching only 60–70 mm (2.4–2.8 in).

The redfin bully is a species of freshwater fish in the family Eleotridae endemic to New Zealand. Being amphidromous, it spends part of its life cycle at sea. Males have distinctive bright red patterns and stripes on their fins. Adults grow to an average of 80–100 mm (3.1–3.9 in) total length, with a maximum of 120 mm (4.7 in).

Gobiomorphus is a genus of fishes in the family Eleotridae native to New Zealand and Australia. They are typically small, benthic fishes with large, rounded fins and two dorsal fins. Many have an amphidromous lifecycle: the eggs are laid in fresh water, but the fry are dispersed to sea soon after hatching, and grow there for several months before returning to fresh water.

Gobiomorphus australis, the striped gudgeon, is a fish in the family Eleotridae, native to eastern Australia. It can be found in a wide variety of habitats from clear streams with rapid currents to muddy stillwaters such as ponds and waterholes. Juveniles are common in estuaries near rocks, submerged logs and among vegetation. They are good climbers and are able to clamber over wet rocky surfaces such as rapids and waterfalls.
