Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.01413 (0.00627 - 0.03183), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		4.5   ±0.80 se; based on food items.
Resilience
(Ref. 120179) 		Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		High to very high vulnerability (68 of 100). 🛈
Price category
(Ref. 80766) 		Very high.
Nutrients
(Ref. 124155) 		Calcium = 15.4 [8.4, 32.6] mg/100g; Iron = 0.466 [0.232, 0.847] mg/100g; Protein = 19.3 [17.5, 21.1] %; Omega3 = 0.194 [0.109, 0.341] g/100g; Selenium = 14.4 [6.3, 32.3] μg/100g; VitaminA = 92.8 [27.0, 354.4] μg/100g; Zinc = 0.574 [0.363, 0.884] mg/100g (wet weight);
