Biology     Glossary (e.g. epibenthic)

Found on sandy bottom, from near shore to 366 m (Ref. 2850 ). Little commercial importance because of its small size (Ref. 2850 ).

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

Distinct pairing (Ref. 205 ). Oviparous (Ref. 101737 ). Females produce numerous eggs in multiple spawnings during a prolonged spawning period (Ref. 101737 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 5.7 - 15.1, mean 8.9 °C (based on 49 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00741 (0.00325 - 0.01693), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.4   ±0.52 se; based on food items. Resilience (Ref. 120179 ):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100). Price category (Ref. 80766 ):   Very high . Nutrients (Ref. 124155 ):  Calcium = 169 [74, 363] mg/100g; Iron = 1.44 [0.65, 2.90] mg/100g; Protein = 17.2 [15.1, 19.3] %; Omega3 = 0.274 [0.141, 0.553] g/100g; Selenium = 42.1 [19.0, 95.1] μg/100g; VitaminA = 7.5 [1.8, 32.5] μg/100g; Zinc = 0.811 [0.520, 1.232] mg/100g (wet weight);
