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=0.00794 (0.00351 - 0.01798), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.2   ±0.3 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (tmax=3.7; tm=1.4; K=0.8).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (17 of 100). 🛈
Nutrients
(Ref. 124155) 		Calcium = 142 [54, 392] mg/100g; Iron = 1.32 [0.59, 3.33] mg/100g; Protein = 16.4 [14.4, 18.5] %; Omega3 = 0.955 [0.488, 1.812] g/100g; Selenium = 60.5 [22.5, 174.5] μg/100g; VitaminA = 32.2 [7.2, 182.9] μg/100g; Zinc = 0.986 [0.588, 1.591] mg/100g (wet weight); based on nutrient studies.
