Cyclops abyssorum divergens is a cyclopoid copepod with a native range that extends across southern and central Europe to southwest Asia. It has been introduced and become established outside of its native range in western Lake Erie in North America; impacts associated with this introduction are unknown. No trade history was found, and the State of Hawaii restricts private and commercial use of all species in the genus Cyclops. The history of invasiveness is Data Deficient. Substantial taxonomic uncertainty was identified during this assessment, with many sources identifying this species as C. divergens or other synonyms. The climate match for the contiguous United States was categorically high with the highest matches occurring in western States, the Midwest, Great Lakes basin, and portions of the Mid-Atlantic and Northeast. The certainty of this assessment is low due to a lack of biological information, taxonomic uncertainty, and unknown impacts of introduction. The overall risk assessment category for C. divergens is Uncertain.

The Fish and Aquatic Conservation program leads aquatic conservation efforts for the U.S. Fish and Wildlife Service. We are committed to tackling the nation’s highest priority aquatic conservation and recreational challenges to conserve, restore, and enhance fisheries for future generations.
Aquatic invasive species cause tremendous harm to our environment, our economy, and our health. They can drive out and eat native plants and wildlife, spread diseases, and damage infrastructure. We work to protect our waterways and the communities that depend on them from the threat of invasive...
