Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 1; Raios dorsais (total) : 7; Raios anais : 39 - 46. Abdomen with a well-developed median keel extending from throat to origin of anal fin. Dorsal fin advanced in position, with a strongly serrated spine; pectoral spines as long as or slightly longer than dorsal spine, strong, denticulated along their inner edge; pelvic fins small; anal fin low, long; adipose fin very small (Ref. 4792). Single, oval-shaped patch of teeth on each side of palate; eye large (Ref. 12693).
Body shape (shape guide): elongated.
Occur in large and medium-sized rivers (Ref. 12693). Found in rapids and in deeper slower reaches (Ref. 37771). Common in the middle Mekong before the flood season where it is found in the lower reaches of tributary streams along with most of the cyprinids which would be found in the main stream of the Mekong when the water is clear. Feeds on terrestrial and aquatic insects along with small amounts of plant matter. Marketed fresh (Ref. 12693).
