Short description Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 14-16; Anal spines: 3; Anal soft rays: 7 - 9. Head spines weak - nasals present, preocular and parietal spines usually absent, supraocular, postocular, tympanic, coronal and nuchal spines absent (Ref. 27437). May have a prominent symphyseal knob; posterior edge of anal fin vertical (Ref. 27436). Caudal fin nearly truncate but slightly forked (Ref. 6885). Olive green to greenish brown with some light mottling dorsally, light ventrally; fins yellowish green, ventral fins often tinged in orange (Ref. 27436).

Biology     Glossary (e.g. epibenthic)

Form schools in open water along steeply sloping shores or above rocky reefs; also holes up amid cracks and crevices of the sea floor (Ref. 27436). Juveniles found around floats and pilings (Ref. 27436). Feed on pelagic crustaceans, fishes and squids (Ref. 6885). Viviparous (Ref. 34817). Filleted, then sold fresh or frozen, with other rockfishes (Ref. 27436).

Estimates based on models

Preferred temperature (Ref. 115969): 4.2 - 11.4, mean 7.5 (based on 44 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.6 se; based on diet studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (K=0.16; tm=6-7; tmax=64).
Fishing Vulnerability (Ref. 59153):  High vulnerability (56 of 100).
Climate Vulnerability (Ref. 125649):  Low to moderate vulnerability (28 of 100).
Price category (Ref. 80766):   Low.
