Biology     Glossary (e.g. epibenthic)

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.02291 (0.01128 - 0.04653), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.3   ±0.61 se; based on food items.
Generation time 1.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience
(Ref. 120179) 		High, minimum population doubling time less than 15 months (K=0.9;).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (15 of 100). 🛈
Price category
(Ref. 80766) 		Unknown.
Nutrients
(Ref. 124155) 		Calcium = 124 [64, 193] mg/100g; Iron = 0.879 [0.518, 1.468] mg/100g; Protein = 18.6 [17.5, 19.8] %; Omega3 = 0.114 [0.068, 0.187] g/100g; Selenium = 26 [14, 50] μg/100g; VitaminA = 57.4 [17.2, 188.2] μg/100g; Zinc = 1.58 [1.05, 2.31] mg/100g (wet weight);
