Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5157 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.5   ±0.37 se; based on food items.
Resilience
(Ref. 120179) 		Very Low, minimum population doubling time more than 14 years (K=0.2-0.6; tmax=60; Assuming tm=4).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (35 of 100). 🛈
Climate Vulnerability
(Ref. 125649) 		High to very high vulnerability (66 of 100). 🛈
Price category
(Ref. 80766) 		High.
Nutrients
(Ref. 124155) 		Calcium = 30 [17, 50] mg/100g; Iron = 0.404 [0.230, 0.657] mg/100g; Protein = 18.9 [17.8, 19.9] %; Omega3 = 0.81 [0.50, 1.33] g/100g; Selenium = 17.1 [8.9, 34.6] μg/100g; VitaminA = 12 [4, 39] μg/100g; Zinc = 0.525 [0.368, 0.762] mg/100g (wet weight);
