Vol. 76 (4) 2024 ARTICLES A Survey of the Kremenski Lakes (Pirin National Park) Suggests that the Vairone Telestes souffia Risso, 1826 (Actinopterygii: Cyprinidae) Is Not a Native Species of the Fauna of Bulgaria

Vairone Telestes souffia is known from Bulgaria based on two specimens sampled from the Lower Kremensko Lake (Pirin National Park) in 1988. A survey of the fish fauna conducted in August 2021 in Lower and Middle Kremensko Lakes suggests that there are not a population of this species at these localities. The only record from 1988 is recognised as a possible consequence from an unregulated fish introduction. Therefore, this study suggests that Telestes souffia has to be excluded from the list of species needing conservational measures in Bulgaria.
