Biology     Glossary (e.g. epibenthic)

Adults occur over sand and gravel substrates to depths of 339 m; larvae collected over depths less than 1,000 m (Ref. 37594). Feed on mollusks, polychaete worms, crustaceans, brittle stars, and fishes (Ref. 6885). A tasty food fish; in some years commercial catch in Canada reaches 3,000 t (Ref. 2850).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00541 - 0.01765), b=3.07 (2.91 - 3.23), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.4 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.15; tm=9; tmax=26).
Vulnerability (Ref. 59153):  High vulnerability (57 of 100) .
Price category (Ref. 80766):   Medium.
