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=0.01000 (0.00495 - 0.02022), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.6   ±0.5 se; based on size and trophs of closest relatives
Generation time 6.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience
(Ref. 120179) 		Low, minimum population doubling time 4.5 - 14 years (tmax=19; tm=5).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (43 of 100). 🛈
Price category
(Ref. 80766) 		Medium.
Nutrients
(Ref. 124155) 		Calcium = 21.7 [7.4, 71.5] mg/100g; Iron = 0.405 [0.159, 0.988] mg/100g; Protein = 19.1 [17.9, 20.3] %; Omega3 = 0.459 [0.179, 1.165] g/100g; Selenium = 37.7 [13.1, 121.2] μg/100g; VitaminA = 116 [39, 341] μg/100g; Zinc = 0.594 [0.283, 1.144] mg/100g (wet weight);
