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=0.01318 (0.00760 - 0.02286), b=2.98 (2.84 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.6   ±0.5 se; based on size and trophs of closest relatives
Generation time 1.8 ( 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 (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (24 of 100). 🛈
Nutrients
(Ref. 124155) 		Calcium = 70.2 [48.8, 112.9] mg/100g; Iron = 1.01 [0.66, 1.50] mg/100g; Protein = 20.2 [17.7, 22.4] %; Omega3 = 0.144 [0.098, 0.212] g/100g; Selenium = 33.6 [20.9, 56.5] μg/100g; VitaminA = 38.4 [8.3, 213.7] μg/100g; Zinc = 2.43 [1.84, 3.18] mg/100g (wet weight);
