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=0.00309 (0.00144 - 0.00663), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.5   ±0.37 se; based on food items.
Resilience
(Ref. 120179) 		Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability
(Ref. 59153) 		Low to moderate vulnerability (31 of 100). 🛈
