Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00135 (0.00106 - 0.00172), b=3.50 (3.44 - 3.56), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level
(Ref. 69278) 		3.9   ±0.62 se; based on food items.
Generation time 5.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm<5).
Fishing Vulnerability
(Ref. 59153) 		Moderate to high vulnerability (51 of 100). 🛈
Climate Vulnerability
(Ref. 125649) 		High to very high vulnerability (68 of 100). 🛈
Price category
(Ref. 80766) 		High.
