(Dories) > Zeidae
Etymology: Zenopsis: Particle zen, derived from zao = to give life + Greek, opsis = appearance; nebulosa: nebulosus meaning dark or clouded--a dark Zeus-like fish (Ref. 4525). More on authors: Temminck & Schlegel.
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 30 - 800 m (Ref. 27124), usually 50 - 600 m (Ref. 27114). Deep-water; 41°N - 54°S, 72°E - 70°W
Indo-Pacific: Japan, northwest shelf of Australia to Broken Bay in New South Wales, New Zealand (Ref. 6390), and elsewhere in the region. Eastern Pacific: off central and southern California, USA (Ref. 2850); and on the seamounts of the Nazca Ridge in the Peru area (Ref. 27131).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 25 - 40 cm
Max length : 70.0 cm TL male/unsexed; (Ref. 9563); max. published weight: 3.0 kg (Ref. 27124); max. reported age: 45 years (Ref. 58312)
Occur in deeper trawling grounds of the continental shelf and slope, close to the sea bed (Ref. 559). Caught by Japanese trawlers during winter (Ref. 559). Excellent food fish.
It is not known whether individuals undergo a single spawning or a series of spawnings over the winter months in southern Australia (Ref. 6390).
