Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 4 - 5; Dorsal soft rays (total): 1 - 7; Anal spines: 1 - 2; Anal soft rays: 9 - 8. Adults are transparent or yellowish in color (Ref. 13460). A few black specks on snout and chin present in some specimen, others have specks scattered over back of head and a row along the base of anal fin (Ref. 439).
Probably live on or near the bottom in deeper parts of the lake (Ref. 439). Often seen in large schools during the rainy season along the shore (Ref. 439). Females are larger than males (Ref. 439). Cooked with vinegar, fried in cakes, or pickled and stewed (Ref. 439). Also prepared as fish sauce or steamed wrapped in banana leaves (Ref. 13460).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Spawning occurs in freshwater afterwhich eggs and larvae are washed down by the river current into the sea (Ref. 110258).
