The Pahranagat spinedace, (Lepidomeda altivelis) is an extinct fish that originally inhabited the Pahranagat Valley in Nevada, United States.
Herring are forage fish, mostly belonging to the family of Clupeidae.
The Clear Lake splittail was endemic to California's Clear Lake and its tributaries until its numbers severely declined due to competition from the introduced bluegill and alterations to the flow of inlet streams. In greatly reduced numbers, the Clear Lake Splittail barely persisted until the 1967 introduction to surrounding lakes of the inland silverside as an experiment by the Department of Fish & Game. A fisherman supposedly introduced the silverside via bait bucket into Clear Lake. This dealt the final blow to the Clear Lake splittail, which had similar feeding habits. All of the splittails were taken by fishermen or have been eaten by catfish and large mouth bass. No Clear Lake splittails have been captured since the early 1970s, and the species is presumed to be extinct.

The southern leatherside chub is a species of freshwater ray-finned fish from the family Cyprinidae, the carps and minnows. It is endemic to Utah in the United States. It is found in slow-flowing pools and backwaters, usually over substrates consisting of mud or sand, of creeks and small to medium-sized rivers. Within Utah, this species is found on the southeastern margins of the Bonneville Basin; it has been recorded from the American Fork, Provo River, and Spanish Fork drainages of the Utah Lake Basin and the San Pitch River, East Fork Sevier River, Beaver River, and the lower, middle, and upper Sevier River drainages of the Sevier River Basin; it has now apparently been extirpated from the Provo River at Utah Lake and from the Beaver River. It is threatened by the fragmentation of its habitat caused by water abstraction for irrigation, damming, urbanization, and poor farming practices. It is also threatened by introduced predatory fish such as the brown trout.
