Short description Identification keys | Morphology | Morphometrics

Vertebrae: 42 - 44. Both sides of the body with 7-11 large and blackish spots. Deep body with clearly convex dorsal profile. Head length shorter than body depth. Snout length shorter or equal to postorbital head length. Lips not developed, lateral lobes of lower lip narrow, without folds, the median process large and marked. Barbel length slightly thick, 1/2-2/3 of eye diameter. Dorsal spine strong, equal to HL. Origin of dorsal fin nearer the tip of snout than the caudal base (Ref. 38453). Anal fin with 6 1/2 branched anal rays; last simple dorsal ray ossified, spine-like (Ref. 43281).

Biology     Glossary (e.g. epibenthic)

Adults usually found in streams and creeks with moderate flow and sandy bottom (Ref. 43281). Feed mainly on insects and mollusks in summer and on crustaceans in winter (Ref. 1441)

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Mature at 3 years of age. Spawns from May to June, with water temperatures from 19-25 C°. Eggs are pasted at underwater plants. Egg diameter about 2mm. Development time about 4 days. Larvae live pelagic for the first 6 days.
