Biologi     Daftar kata (contoh epibenthic)

Inhabits bottom of lakes and large rivers (Ref. 10294), usually in 5-9 m depth, over mud, sand, and gravel. Occasionally enters brackish water. A specimen caught in 1952 was reputed to have been 152 years old (Ref. 6866). Search for food, with the aid of the sensory ability of the barbels, by constantly moving close to the substrate. Omnivorous, virtually anything edible that enters the mouth is sucked up and consumed. The food is worked or pulled in the mouth, often partly ejected and sucked in again (Ref. 1998). Spawning sites are rocky and boulder filled areas along the outside bend of rivers (Ref. 41542). Smoked and in 1951, Canada, 2,000 lbs. of caviar were made from the eggs (Ref. 37032). Threatened due to over harvesting, habitat loss and pollution (Ref. 58490).
