deskripsi pendek Morfologi | Morfometrik

Extended snouts; four barbels in front of the mouth (Ref. 4639). The back is light grey to dark brown colored. The belly color varies from white to clear yellow. Five row s of scutes: 10-19D, 32-59L, 7-16V. Small star-like scutes between the main ones. Clearly slit inferior lip (Ref. 40476).

Biologi     Daftar kata (contoh epibenthic)

Found in deep and shallow parts of rivers, with moderate to swift current usually at depths of 1 to 8 m (Ref. 57765). Adults live essentially in freshwater although some fish frequently occur in estuaries. Males are sexually mature between 9 and 29 years; females between 9 and 34 years (Ref. 57765). Spawn in main river channel over stone-gravel or gravel-sand bottom and with strong current (Ref. 59043).

Life cycle and mating behavior Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | Larva

Potamodromous species (Ref. 57765). In a natural environment, males reach sexual maturity at 9-1 5 years of age and females at 16-20 years (in water recirculation systems, sexual maturity can first occur at 5 years). Spawning happens in the summer and generally every two years. Membranes on eggs become increasingly more sticky after fertilization and this allows them to stick to the substratum. This can become a problem in nurseries, but it is solved by washing the eggs in clay or diatomaceous earth suspensions. Caviar (not fecundated ovocites ) can be over 1 0% of the corporal weight of a mature female. Incubation lasts about 1 6 days (at 10-1 5°). Larval development lasts about 20 days (at 18°). Egg size 3.0-3.6 mm, larval length at hatching 10-12 mm.
