Barbatula quignardi, the Languedoc stone loach or Les stone loach,, is a species of ray-finned fish in the genus Barbatula, which belongs to the family Nemacheilidae, the stone loaches. [3]
This loach is found in the drainage of Ebro, Bidasoa and Nervión in Spain and Lez, Tech, Adour and Garonne drainages in France.[4]
Populations of B. quignardi in the Iberian Peninsula have been negatively impacted by various invasive species, including the aggressive signal crayfish (Pacifastacus leniusculus).[5]
