Vedoilla

Vedoilla is a genus of small, freshwater fish belonging to the family Cyprinidae, which includes minnows and carps. The genus is native to the eastern United States, with species found in the Mississippi River basin and its tributaries. Vedoilla species are known for their small size, typically ranging from 2 to 4 inches in length, and their preference for clear, well-oxygenated waters.

The genus was first described by American ichthyologist David Starr Jordan in 1881. It includes two recognized species: Vedoilla chui and Vedoilla opercularis. Vedoilla chui is found in the upper Mississippi River and its tributaries, while Vedoilla opercularis is found in the lower Mississippi River and its tributaries.

Vedoilla species are omnivorous, feeding on a variety of aquatic insects, small crustaceans, and plant material. They are also known to feed on the eggs and larvae of other fish species. Vedoilla are important prey species for larger fish, such as bass and walleye, and they play a role in the food web of their aquatic ecosystems.

Vedoilla species are generally considered to be of low conservation concern, as they are widespread and have stable populations. However, like all fish species, they are subject to the impacts of habitat degradation, pollution, and climate change. Conservation efforts for Vedoilla species focus on protecting and restoring their habitats, as well as reducing human impacts on their ecosystems.
