Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00219 (0.00083 - 0.00575), b=3.04 (2.81 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		3.8   ±0.4 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) 		Moderate vulnerability (38 of 100). 🛈
