生物学特性     字汇 (例如 epibenthic)

Benthopelagic to bathypelagic in about 400 and 1200 m depth. Minimum depth from Ref. 1371. Form large schools at 600 to 900 m depth (Ref. 9988). Feed on a variety of fish and invertebrates, but primarily on pelagic crustaceans such as shrimps, amphipods and cumaceans; cephalopods and lantern fishes constitute a lesser portion of the diet. Batch spawner (Ref. 51846). This species is currently facing overexploitation in the North Atlantic. Utilized frozen and for fishmeal; can be fried and baked (Ref. 9988).

在大约 400 与 1200 公尺深中的底栖大洋性到底栖大洋性。 在 600 到 900 公尺深形成大群鱼群。 (参考文献 9988) 捕食多种鱼与无脊椎动物, 但是主要地在大洋性的甲壳动物例如虾,片脚类动物与 cumaceans 上; 头足类动物与灯笼鱼构成食性的较少的部分。 这种现在正在北大西洋中面对过渔。 冷冻使用了与用于鱼粉; 能被油炸而且烧烤。 (参考文献 9988)

Estimates based on models

Preferred temperature (Ref. 115969): 2.7 - 9.4, mean 4.5 (based on 270 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00111 - 0.00431), b=3.20 (3.03 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.7   ±0.56 se; based on food items.
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (K=0.1; tm=9-11; tmax=54; Fec=10,000).
Prior r = 0.27, 95% CL = 0.18 - 0.40, Based on 4 full stock assessments.
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100).
Climate Vulnerability (Ref. 125649):  Moderate vulnerability (38 of 100).
