(Scorpionfishes) > Sebastidae
(Rockfishes, rockcods and thornyheads) > Sebastinae
Etymology: Sebastes: Greek, sebastes = august, venerable (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 70 - 558 m (Ref. 27437). Temperate; 55°N - 45°N
Northeast Pacific: Bowers Bank and Petrel Bank in the Aleutian chain to Newport, Oregon, USA.
Length at first maturity / Size / Weight / Age
Maturity: Lm 23.0  range ? - ? cm
Max length : 38.0 cm TL male/unsexed; (Ref. 27437); max. reported age: 47 years (Ref. 39247)
soft rays: 6 - 7;
Vertebrae: 26. Head spines strong to moderate - nasal, preocular, postocular, tympanic and parietal spines present, nuchals usually absent, supraocular and coronal spines absent (Ref. 27437). Weak symphyseal knob; 2nd anal fin spine longer than 3rd (Ref. 27437). Caudal fin moderately indented (Ref. 6885). Pink to red with irregular dark markings interrupted by lighter band along two thirds of lateral line; caudal fin with dark membranes and pink or red band terminating fin; anal fin has black between 2nd and 3rd spines; tip of spinous dorsal black (Ref. 27437).
Viviparous (Ref. 34817). Too small to be of high commercial value (Ref. 27437).

Estimates based on models
Preferred temperature (Ref. 115969
): 3.7 - 7.1, mean 5.2 °C (based on 28 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=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.6 se; based on size and trophs of closest relatives
Generation time: 8.0 ( 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=47).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (50 of 100) .
