Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 9 - 12; Rückenflossenweichstrahlen (insgesamt) : 12; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 7 - 9.

A deepwater species, occurs in seamounts (Ref. 89357). Adults occur generally over rough ground from the central shelf (about 100 m) to the shelf edge and down to the upper slope. Juveniles are found in surface waters, perhaps school in association with drifting weed. Feed on barracouta and pilchards, in addition to various bottom-dwelling fish. Are primary gonochorists (Ref. 58421). Preyed upon by sperm whales (Ref. 9072). It is taken by droplining down to 400 m, and is sometimes seen in the trawled catch. Utilized fresh and frozen; can be steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Severely overfished (Ref. 89357).

Estimates based on models

Preferred temperature (Ref. 123201): 8.6 - 16, mean 11.7 °C (based on 143 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.8125 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00765 - 0.01500), b=2.99 (2.89 - 3.09), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.77 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (tm=10-13; tmax=60).

Fishing Vulnerability (Ref. 59153): High vulnerability (59 of 100).

Climate Vulnerability (Ref. 125649): High to very high vulnerability (70 of 100).

Preiskategorie (Ref. 80766): Low.

Nutrients (Ref. 124155): Calcium = 34 [20, 61] mg/100g; Iron = 0.904 [0.538, 1.528] mg/100g; Protein = 21 [20, 22] %; Omega3 = 0.563 [0.318, 1.046] g/100g; Selenium = 55.6 [29.6, 108.8] μg/100g; VitaminA = 9.09 [3.16, 24.94] μg/100g; Zinc = 0.368 [0.267, 0.532] mg/100g (wet weight); based on nutrient studies.
