Description synthétique Morphologie | Morphométrie

Head large; thick and fleshy lips; nostrils tubular. First dorsal fin high, with a strong serrated spine and 6 rays. Skin tough and smooth. Body coloration in adults vary from olive-green to brown, black or purplish dorsally and white ventrally. Urogenital papilla triangular in females; longer and cylindrical in males.

Biologie     Glossaire (ex. epibenthic)

Adults inhabit slow moving streams, lakes and ponds with fringing vegetation. They swim close to sand or gravel bottoms. More abundant in lakes than in flowing water (Ref. 44894). Usually solitary but juveniles sometimes form loose aggregations. Mainly bottom-feeders (Ref. 44894). Feed on insect larvae, prawns, crayfish, mollusks, and small fishes. Breeding occurs between spring and mid-summer when water temperatures rise to between 20° and 24°C (Ref. 44894). Utilized for human consumption.

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

Water temperature (20-24 °C) considered the primary spawning stimulus. There is direct pairing during spawning. Male builds nest (0.6-2.0 m in diameter) and cares for eggs in the nest up to 2 weeks. The nest is made of gravel and rocks with a central sandy depression in which the female deposits up to 20,000 eggs depending on her size (Ref. 5259). Eggs scattered into the rubble are tended and guarded by the male after the female departs (Ref. 205). Hatching occurs in 7-10 days at 18°C (Ref. 240).
