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=0.01318 (0.00635 - 0.02739), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.4   ±0.5 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (25 of 100). 🛈
