Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00575 (0.00365 - 0.00908), b=3.07 (2.94 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		3.8   ±0.7 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability
(Ref. 59153) 		Moderate to high vulnerability (53 of 100). 🛈
Nutrients
(Ref. 124155) 		Calcium = 110 [16, 2,849] mg/100g; Iron = 1.33 [0.12, 18.12] mg/100g; Protein = 14.6 [12.9, 16.4] %; Omega3 = 0.69 [0.17, 2.70] g/100g; Selenium = 6.27 [0.76, 40.18] μg/100g; VitaminA = 224 [11, 4,346] μg/100g; Zinc = 1.74 [0.13, 20.44] mg/100g (wet weight); based on nutrient studies.
