Teleostei (teleosts) > Zeiformes (Dories) > Oreosomatidae (Oreos) > Oreosomatinae
Etymology: Allocyttus: Greek, allos = other + Greek, kyttaros, kytos = a convex cavityniger: niger refers to the blackish color of freshly caught specimens. It also reflects the common name "black oreo", which has been widely used in the New Zealand deepwater fishery for several years (Ref. 27159).

Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 36 - ? cm
Max length : 47.0 cm TL male/unsexed; (Ref. 6390); common length : 35.0 cm TL male/unsexed; (Ref. 9258); max. published weight: 1.5 kg (Ref. 6390); max. reported age: 100 years (Ref. 27140)

Biology     Glossary (e.g. epibenthic)

Found close to the sea bed in deep water. Form large shoals over rough ground near pinnacles and canyons. Juveniles are pelagic and inhabit oceanic waters. They tend to be dispersed over smooth grounds (Ref. 6390). Feed mainly on salps and benthic crustaceans (Ref. 27150). Eggs float near the sea surface and larvae also inhabit surface waters (Ref. 6390). Based on trawl catch rates, there is no evidence of vertical migration during day or night (Ref. 27150).

Estimates based on models

Preferred temperature (Ref. 123201): 2.1 - 6.8, mean 5.1 °C (based on 63 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5635   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00738 - 0.02832), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.50 se; based on food items.
Generation time: 56.1 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (tmax=100; tm=27; Fec >5,000).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (69 of 100).
Climate Vulnerability (Ref. 125649):  Moderate vulnerability (40 of 100).
