Dorsal spines (total): 15 - 16; Dorsal soft rays (total): 8-10; Anal spines: 3; Anal soft rays: 4 - 6. Head spines very strong - nasal, preocular, supraocular, postocular, tympanic, parietal and nuchal spines present, coronal spines absent (Ref. 27437). Spiny ridge on sub-orbital bone; gill chamber mostly dark; third dorsal spine longest; slight notch on pectoral fin (Ref. 27437). Caudal fin slightly rounded (Ref. 6885). Red rockfish with some black on fins (Ref. 27437).

Biology     Glossary (e.g. epibenthic)

Adults occur on soft bottom of offshore waters (Ref. 2850). Juveniles occur in midwater (Ref. 2850). Oviparous (Ref. 205). Eggs are spawned in pelagic gelatinous masses (Ref. 59312).

Estimates based on models

Preferred temperature (Ref. 115969): 3.1 - 6.9, mean 4.1 (based on 86 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00410 - 0.02027), b=3.09 (2.89 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tm=6; tmax=45 (validate age: 27 yrs)).
Prior r = 0.06, 95% CL = 0.04 - 0.09, Based on 1 stock assessment.
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (66 of 100).
