Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 8 - 9; Rückenflossenweichstrahlen (insgesamt) : 16 - 18; Afterflossenstacheln: 1 - 2; Afterflossenweichstrahlen: 12 - 14; Wirbelzahl: 31. Body almost uniformly dark brown, becoming almost black with age. Pelvic fins well developed, with I spine and 5 soft rays (Ref. 9784). Prominent lateral keel on caudal peduncle, flanked by smaller accessory keels above and below (Ref. 26938).

Occurs mainly over the continental slope, down to 200 m and more (Ref. 6181). Migrates upward at night (Ref. 6181). Feeds on squid, crustaceans and a wide variety of fishes (Ref. 6181). Flesh oily and may have purgative properties (Ref. 9784). Sometimes caught by tuna long-liners (Ref. 26938). Marketed frozen and as fish cakes in Japan (Ref. 9302).

Estimates based on models

Preferred temperature (Ref. 115969): 7 - 14.4, mean 9.9 (based on 642 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01175 (0.00597 - 0.02312), b=2.98 (2.79 - 3.17), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.67 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming tm=4-5).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Climate Vulnerability (Ref. 125649): Moderate vulnerability (39 of 100).

Preiskategorie (Ref. 80766): Medium.
