Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00275 (0.00131 - 0.00577), b=3.16 (2.98 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		4.0   ±0.7 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm<4).
Fishing Vulnerability
(Ref. 59153) 		High vulnerability (55 of 100). 🛈
