Etymology: Dissostichus: Greek, disso = twice, one or other + Greek, stix, stichos =line, row (Ref. 45335); eleginoides: eleginoides deriving from the genus Eleginops for an assumed resemblance to that genus (Ref. 11892).

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 8 - 10; Rückenflossenweichstrahlen (insgesamt) : 28 - 30; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 28 - 30; Wirbelzahl: 53 - 54. Lateral line scales 88-104 (upper), 61-77 (lower).

At 12-15 cm TL, semi-pelagic juveniles become demersal at 150-400 m depth (Ref. 55957). Adults migrate to deeper habitats at depths greater than 1,000 m (Ref. 55957). Utilized as food fish (Ref. 4931).

May spawn for the first time from around 8-10 years of age (Ref. 71843).

Estimates based on models

Preferred temperature (Ref. 123201): 1.8 - 8.8, mean 4.5 °C (based on 1109 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00631 (0.00361 - 0.01104), b=3.15 (2.99 - 3.31), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.8 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec=230,000; tmax>=21).

Prior r = 0.33, 95% CL = 0.21 - 0.49, Based on 1 full stock assessment.

Fishing Vulnerability (Ref. 59153): Very high vulnerability (81 of 100).

Climate Vulnerability (Ref. 125649): Moderate to high vulnerability (47 of 100).

Preiskategorie (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 11.6 [6.5, 19.8] mg/100g; Iron = 0.335 [0.184, 0.568] mg/100g; Protein = 17.6 [15.9, 19.6] %; Omega3 = 0.744 [0.429, 1.253] g/100g; Selenium = 31.2 [16.4, 58.5] μg/100g; VitaminA = 9.39 [3.17, 28.34] μg/100g; Zinc = 0.313 [0.219, 0.453] mg/100g (wet weight); based on nutrient studies.
