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=0.01072 (0.00537 - 0.02137), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		3.4   ±0.45 se; based on food items.
Generation time 3.7 (3.3 - 5.7) years. Estimated as median ln(3)/K based on 12 growth studies.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (K=0.18-0.36; tmax=12).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (35 of 100). 🛈
Price category
(Ref. 80766) 		Very high.
Nutrients
(Ref. 124155) 		Calcium = 132 [79, 240] mg/100g; Iron = 1.12 [0.69, 1.86] mg/100g; Protein = 17.1 [14.9, 18.9] %; Omega3 = 0.155 [0.088, 0.270] g/100g; Selenium = 76.6 [39.2, 154.7] μg/100g; VitaminA = 26.6 [9.1, 76.2] μg/100g; Zinc = 1.07 [0.75, 1.51] mg/100g (wet weight);
