Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Nototheniidae (Cod icefishes)
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).

Environment / Climate / Range Ecology

Marine; pelagic-oceanic; oceanodromous (Ref. 51243); depth range 50 - 3850 m (Ref. 11892), usually 70 - 1500 m (Ref. 2121). Temperate, preferred 7°C (Ref. 107945); 33°S - 66°S, 77°W - 180°E (Ref. 54228)

Southeast Pacific and Southwest Atlantic: southern Chile round the coast to Patagonia (Argentina) and the Falkland Islands. Southwest Pacific: Macquarie Island. Southern Ocean: South Georgia. Also known from sub-Antarctic islands and seamounts of the Indian sector.

Length at first maturity / Size / Weight / Age

Maturity: L_m ?, range 38 - 60 cm
Max length : 215 cm TL male/unsexed; (Ref. 2121); common length : 70.0 cm TL male/unsexed; (Ref. 2121); max. published weight: 9.6 kg (Ref. 58336); max. reported age: 31 years (Ref. 87879)

Short description Morphology | Morphometrics

Dorsal spines (total): 8 - 10; Dorsal soft rays (total): 28-30; Anal spines: 0; Anal soft rays: 28 - 30; Vertebrae: 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 of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00603 (0.00354 - 0.01026), b=3.18 (3.03 - 3.33), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 4.0 ±0.68 se; Based on food items.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec=230,000; tmax>=21).

Prior r = 0.27, 2 SD range = 0.14 - 0.53, log(r) = -1.31, SD log(r) = 0.34, Based on: 1 M, 5 K, 2 tgen, 2 tmax, 2 Fec records

Vulnerability (Ref. 59153): High to very high vulnerability (71 of 100) .

Price category (Ref. 80766): Very high.
