Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00398 (0.00259 - 0.00612), b=3.03 (2.91 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		3.7   ±0.55 se; based on food items.
Resilience
(Ref. 120179) 		Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability
(Ref. 59153) 		Very high vulnerability (83 of 100). 🛈
Price category
(Ref. 80766) 		Medium.
Nutrients
(Ref. 124155) 		Calcium = 15.1 [3.0, 72.8] mg/100g; Iron = 0.658 [0.171, 1.913] mg/100g; Protein = 17.5 [14.7, 19.9] %; Omega3 = 0.401 [0.138, 1.492] g/100g; Selenium = 26 [8, 88] μg/100g; VitaminA = 7.9 [2.6, 23.9] μg/100g; Zinc = 0.562 [0.279, 1.023] mg/100g (wet weight);
