Abstract This is the first description of otoliths (sagitta, asteriscus, and lapillus) European barbel ( Barbus sclateri , Pisces: Cyprinidae), as well location, procedure for extracting them preparing age growth studies. The were observed by light scanning electron microscopy. With this last technique each otolith had a variable external crystalline morphology which may be related to different rates crystals. When seen through reflected light, lapillus asteriscus showed opaque translucent radial bands, those in more clearly defined than other otolith.
