Rayons mous dorsaux (Total): 8; Rayons mous anaux: 8. Lateral line complete with 66-84 scales; dorsal fin with 8 rays; anal fin with 8 rays; molarlike pharyngeal teeth 1,5--5,1; slender body, somewhat compressed; large eye; long rounded snout; barbel at corner of slightly subterminal mouth; large forked caudal fin; dorsal-fin origin over or in front of pelvic-fin origin; axillary process at pelvic-fin base; dark gray-brown to green above; 2 dark stripes, lower one ending in front of anal fin, on silver yellow side; yellow to brown fins; and large male with red on side, belly mouth, gill cover and pectoral-fin base (Ref. 86798).

Biologie     Glossaire (ex. epibenthic)

Inhabits lakes and slow-flowing areas of small to medium rivers. Common around vegetation (Ref. 86798). Forms schools. Can withstand brackish waters for a limited period (Ref. 1998). Newly hatched individuals school near the shore, moving into deeper water in the summer (Ref. 4569). Feeds mainly on aquatic insects and its larvae and some terrestrial insects (Ref. 10288); but also on planktonic crustaceans, mollusks, and small fishes (Ref. 1998). Preyed upon by fish-eating birds and mammals (Ref. 1998). Utilized as game fish and as food in the past (Ref. 1998).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Spawning fish come close to shore in groups of 50-400. Groups are about 25 to 100 feet apart from each other. Females are crowded by 2 or more males into 1 or 2 inches of water by the shoreline and eggs and sperms are released.
