Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5059 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00851 (0.00525 - 0.01379), b=2.92 (2.77 - 3.07), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		4.0   ±0.66 se; based on food items.
Generation time 2.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience
(Ref. 120179) 		High, minimum population doubling time less than 15 months (K=0.4).
Fishing Vulnerability
(Ref. 59153) 		Low to moderate vulnerability (32 of 100). 🛈
Price category
(Ref. 80766) 		Low.
Nutrients
(Ref. 124155) 		Calcium = 64 [40, 118] mg/100g; Iron = 0.913 [0.588, 1.432] mg/100g; Protein = 19.1 [18.3, 19.9] %; Omega3 = 0.362 [0.252, 0.528] g/100g; Selenium = 25.2 [13.6, 48.0] μg/100g; VitaminA = 16.7 [6.0, 48.2] μg/100g; Zinc = 0.731 [0.549, 1.015] mg/100g (wet weight);
