Distribution Territories | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

North Pacific: Gulf of Alaska to North Pacific Ocean off central California and south of Japan, with center of abundance at the seamounts of the southern Emperor-northern Hawaiian Ridge.

Length at first maturity / Size / Weight / Age

Maturity: Lm 28.0  range ? - ? cm
Max length : 44.0 cm TL male/unsexed; (Ref. 56527); common length : 29.0 cm TL male/unsexed; (Ref. 56527); max. published weight: 1.2 kg (Ref. 56527); max. reported age: 11 years (Ref. 56527)

Biology     Glossary (e.g. epibenthic)

Juveniles epipelagic, adults benthopelagic (Ref. 58302).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Observations based on the lack of occurrence of individuals older than 3 years in the seamounts may suggest that P. wheeleri may spawn in only one or two seasons and die afterwards (Ref. 57888).

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5157 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.4   ±0.4 se; based on diet studies.
Generation time 8.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience
(Ref. 120179) 		Low, minimum population doubling time 4.5 - 14 years (tmax=11; tm = 6-7;).
Fishing Vulnerability
(Ref. 59153) 		Moderate to high vulnerability (54 of 100). 🛈
Price category
(Ref. 80766) 		Unknown.
Nutrients
(Ref. 124155) 		Calcium = 20.7 [10.2, 36.6] mg/100g; Iron = 0.268 [0.145, 0.492] mg/100g; Protein = 17 [16, 18] %; Omega3 = 0.504 [0.252, 1.008] g/100g; Selenium = 21.9 [9.0, 48.0] μg/100g; VitaminA = 26.5 [6.1, 127.1] μg/100g; Zinc = 0.528 [0.354, 0.775] mg/100g (wet weight);
