Tui chub
The Tui chub (Siphateles bicolor) is a species of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, chubs, Eurasian minnows and related fishes. This fish is native to western North America. Widespread in many areas, it is a highly adaptable fish that has historically been a staple food source for native peoples.
The Tui chub has been referred to as both Siphateles bicolor and Gila bicolor in scientific literature; the same is true of several subspecies, such as the Owens Tui Chub (Siphateles bicolor snyderi) also being referred to as Gila bicolor snyderi. Despite the differing names, in this context, both scientific names are referring to the same species and subspecies based on some papers explicitly indicating these names are equivalent.
During the Pleistocene, Tui chub lived in the Great Basin's large pluvial lakes. As time passed, these lakes diminished, and different populations became isolated. The Tui Chub's modern range includes the Lahontan and Central system of the Great Basin, as well as the Owens, Truckee, Carson, Quinn, Humboldt, Columbia Klamath, and Mojave Rivers. It is also found in the Pit River and Goose Lake of the upper Central Valley, California. They can have a strong presence where they are found such as in Pyramid Lake where they are the most abundant species of fish present.
They have historically been abundant enough in the western Great Basin to provide a valuable food source to native peoples living there.
The range of the Tui chub has been controversial in the past with it being debated where exactly this species is native to. There is strong evidence indicating the species is native to Nevada and southern Oregon. It was once thought to be native to Idaho, but that is no longer considered accurate. Data obtained through natural history and the discovery of Tui chub bones in the Columbia River Basin in Washington provides evidence that the Tui chub is also native to the Columbia River Basin region.
The form and appearance of the Tui chub is variable; many were originally described as different species by J. O. Snyder, but have since been reduced to subspecies. Their body shape comes in two forms: either more slender or more plump. In general, mature individuals are characterized by a deep olive above and white below, with a smooth variation in shading along the sides, and a brassy reflection. The fish has broad scales and a relatively large head compared to body. Fins are olive and sometimes tinted with red. The pectoral fins are far forward and low on the body. Length has been recorded at up to 45 centimeters (18 inches); however, 20–25 cm is typical for an adult. They do not display sexual dimorphism, indicating that the females and males look the same.
Tui chubs are found in a variety of habitats, including small, fast-flowing streams, meandering rivers, springs, ponds, and lakes. Their adaptability allows them to live in both high cold lakes, such as Lake Tahoe, and warmer desert streams. Their optimal range for water temperature lies between 15 and 30 °C but they can survive in 2 to 36 °C conditions. Although they are suited for wide range of environments, they are typically found in slow water with abundant vegetation.
In lake habitats such as Walker Lake, Tui chub are heavily preyed upon. They are a key prey item for the Lahontan Cutthroat trout in Walker Lake. Additionally, Tui chub are preyed upon by fish-eating birds.
