Biologie     Glossaire (ex. epibenthic)

Occurs in deep water. Spawns only around margin of Pyramid Lake in Nevada, USA but formerly made spectacular spawning runs up Truckee River in Nevada, USA. Populations were subject to intensive fishing in the 19th and early 20th century; habitats have been greatly altered by water development projects; species is now endangered (Ref. 47054).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00202 - 0.01242), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Très faible, temps minimum de doublement de population supérieur à 14 ans (tm=14-17; Fec=30,000).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100).
Catégorie de prix (Ref. 80766):   Unknown.
