Biology     Glossary (e.g. epibenthic)

Estimates based on models

Preferred temperature (Ref. 123201): 8.4 - 18.3, mean 10.7 °C (based on 229 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.00559 - 0.03107), b=3.05 (2.84 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.50 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (tm=1).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (12 of 100).
Nutrients (Ref. 124155):  Calcium = 155 [85, 298] mg/100g; Iron = 1.43 [0.91, 2.36] mg/100g; Protein = 19.1 [18.3, 20.0] %; Omega3 = 0.368 [0.238, 0.576] g/100g; Selenium = 20.5 [11.1, 39.0] μg/100g; VitaminA = 13.1 [4.8, 35.6] μg/100g; Zinc = 0.956 [0.691, 1.351] mg/100g (wet weight);
