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=0.01660 (0.01038 - 0.02654), b=2.98 (2.85 - 3.11), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.5   ±0.4 se; based on diet studies.
Resilience
(Ref. 120179) 		Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		High vulnerability (63 of 100). 🛈
