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=0.00372 (0.00226 - 0.00610), b=3.06 (2.92 - 3.20), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.5   ±0.37 se; based on food items.
Generation time 1.7 ( 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=0.65).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (22 of 100). 🛈
Price category
(Ref. 80766) 		Very high.
Nutrients
(Ref. 124155) 		Calcium = 241 [117, 514] mg/100g; Iron = 1.32 [0.61, 2.43] mg/100g; Protein = 17.7 [15.6, 19.9] %; Omega3 = 0.274 [0.114, 0.631] g/100g; Selenium = 82.1 [36.5, 177.3] μg/100g; VitaminA = 32.2 [9.6, 103.5] μg/100g; Zinc = 1.41 [0.93, 2.18] mg/100g (wet weight);
