Korte beschrijving Morfologie | Morfometrie

Single row of preanal shields. Soft area on the top of the head absent and black viscera. Large blotches present on anterior half of upper surface of snout and on back. Lower surface whitish (Ref. 37032). Anal fin origin behind dorsal fin origin; scutes on back and along side same color as skin (Ref. 86798).

Biologie     Verklarende woordenlijst (b.v. 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).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00219 - 0.00363), b=3.18 (3.13 - 3.23), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.49 se; based on food items.
Generation time: 49.9 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Weerstandsvermogen (Ref. 120179):  zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (tm=16-26; tmax=97; K=0.04; Fec=50,000).
Kwetsbaarheid (Ref. 59153):  Very high vulnerability (89 of 100) .
Prijsklasse (Ref. 80766):   Unknown.
