Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 90-106; Anal spines: 0; Anal soft rays: 69 - 80; Vertebrae: 49 - 51. Dorsal origin above anterior part of pupil in upper eye, generally low, higher in middle. Caudal spread and slightly lunate. Pectorals small.

Found on various types of bottoms (Ref. 2850). Young are found near shore, moving out to deeper waters as they grow older (Ref. 6885). Older individuals typically move from deeper water along the edge of the continental shelf where they spend the winter, to shallow coastal water (27-274 m) for the summer (Ref. 28499). Feed on fishes, crabs, clams, squids, and other invertebrates (Ref. 6885). Utilized fresh, dried or salted, smoked and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805)
PD₅₀ = 0.7500 many relatives (e.g. carps) 0.5 - 2.0 few relatives (e.g. lungfishes)

Trophic Level (Ref. 69278)
4.1 ±0.2 se; Based on diet studies.

Resilience (Ref. 69278)
Low, minimum population doubling time 4.5 - 14 years (rm=0.2; K=0.05; tm=5-20; tmax=55)

Vulnerability (Ref. 59153)
Very high vulnerability (86 of 100)

Price category (Ref. 80766)
