Biology     Glossary (e.g. epibenthic)

Inhabit continental shelves or around islands. Feed on pelagic crustaceans (Euphausia, Nyctiphanes), cephalopods and fishes (Ref. 6181) like anchovy and pilchard (Ref. 36731). Form schools near the bottom or midwater; sometimes even at the surface at night (Ref. 6181). Prefers temperature between 13° and 18°C (Ref. 36731). Marketed fresh, smoked, canned and frozen; eaten fried, broiled, microwaved and baked (Ref. 9988). Good for fish and chips or smoking; also made into fillet or fish cake in Japan (Ref. 6181).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00236 - 0.01017), b=3.06 (2.87 - 3.25), based on LWR estimates for species & Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.6 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=2-4; tmax=10).
Vulnerability (Ref. 59153):  High vulnerability (63 of 100) .
Price category (Ref. 80766):   Very high.
