(Rockfishes, rockcods and thornyheads) > Sebastinae
Etymology: Sebastes: Greek, sebastes = august, venerable (Ref. 45335); nigrocinctus: From the Latin niger and cinctus, meaning 'black' and 'belt' (Ref. 27436). More on author: Ayres.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 10 - 275 m (Ref. 27436). Temperate; 60°N - 35°N, 150°W - 120°W
Eastern Pacific: Cape Resurrection, Kenai Peninsula, Alaska to Point Buchon, central California, USA.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 61.0 cm TL male/unsexed; (Ref. 2850); max. published weight: 2.2 kg (Ref. 40637); max. reported age: 116 years (Ref. 39247)
soft rays: 6 - 7. Head spines strong - nasal, preocular, supraocular, postocular, tympanic, coronal, parietal and nuchal spines present (Ref. 27437). Strongly concave between eyes; parietal ridges very thick and coarse (Ref. 27437). Caudal fin rounded (Ref. 6885). Light pink to red with 5 or 6 black or dark red bars on body; 2 dark bars radiating from each eye (Ref. 27437).
Inhabit rocky reefs, mainly at depths greater than 10 m (Ref. 27436). Solitary and territorial, defending a home crevice among rocks (Ref. 2850). Juveniles pelagic (Ref. 27436). Viviparous (Ref. 34817). Quickly changes color when disturbed or when there is a change in lighting (Ref. 6885). Caught infrequently and incidentally marketed as rockfish (Ref. 27436). Flesh firm and tasty (Ref. 27436).

Estimates based on models
Preferred temperature (Ref. 115969
): 5.8 - 9.5, mean 7.8 °C (based on 64 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00479 - 0.02087), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.4 se; based on diet studies.
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (tmax=116).
Vulnerability (Ref. 59153
): High to very high vulnerability (71 of 100) .
