First record of the large-scale loach Misgurnus dabryanus (Guichenot, 1872) (Teleostei, Cobitidae) in France
Résumé
A specimen of weatherloach was caught in the Lanterne stream at Chevigney-surl’Ognon (Rhône catchment, Doubs department, eastern France) on the 22nd of July 2020. It was photographed and initially identified as European weatherloach Misgurnus fossilis before being released. Upon further examination of the photographs, looking at the adipose crests on the caudal peduncle, the coloration pattern and morphometric data of the head, the specimen was then correctly identified as a non-native large-scale loach Misgurnus dabryanus, thus being the first record of this species in France. Monitoring must be put in place to know if there is an established population and to follow its possible propagation.
