Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00339 (0.00162 - 0.00707), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.5   ±0.5 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Moderate to high vulnerability (51 of 100). 🛈
