Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00468 (0.00213 - 0.01026), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.9   ±0.62 se; based on food items.
Resilience
(Ref. 120179) 		High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Low to moderate vulnerability (26 of 100). 🛈
