Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 250 cm TL male/unsexed; (Ref. 40637); max. published weight: 255.6 kg (Ref. 4699); max. reported age: 75 years (Ref. 4563)

Biology     Glossary (e.g. epibenthic)

Occur on rock bottoms; near shore, outside kelp beds and along drop-offs (Ref. 2850). Large specimens usually found deeper than 30 m, small ones over sand and in kelp beds mostly from 12-21 m (Ref. 2850). Aggregate for spawning in summer (Ref. 2850). Pelagic spawners (Ref. 56049). Longevity of 90 to 100 years (Ref. 56049) stemmed from speculation on the age of a 557 lb fish caught in 1962, but the oldest age determined from otoliths of a 435 lb fish was 72 to75 years (Ref. 4563). Validated age so far is up to >50 years using bomb radiocarbon (A.H. Andrews, pers. comm.)

Estimates based on models

Preferred temperature (Ref. 115969): 14.8 - 23, mean 20.9 °C (based on 48 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.8125   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00512 - 0.02696), b=3.01 (2.81 - 3.21), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.80 se; based on food items.
Generation time: 22.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (tm=11; tmax=75; also Musick et al. 2000 (Ref. 36717)).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (86 of 100) .
Climate Vulnerability (Ref. 125649):  High vulnerability (62 of 100) .
Price category (Ref. 80766):   Very high.
Nutrients (Ref. 124155):  Calcium = 21.5 [12.0, 40.3] mg/100g ; Iron = 0.669 [0.407, 1.116] mg/100g ; Protein = 20.3 [18.7, 22.1] % ; Omega3 = 0.359 [0.208, 0.682] g/100g ; Selenium = 47 [23, 87] μg/100g ; VitaminA = 17.1 [5.8, 51.1] μg/100g ; Zinc = 0.395 [0.266, 0.577] mg/100g (wet weight);
