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=0.00407 (0.00238 - 0.00697), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.6   ±0.5 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		High, minimum population doubling time less than 15 months (tm<1).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (21 of 100). 🛈
Price category
(Ref. 80766) 		Very high.
