Estimates based on models

Phylogenetic diversity index (Referencia 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00470 - 0.02937), b=2.88 (2.66 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Referencia 69278):  3.1   ±0.3 se; based on size and trophs of closest relatives
Resiliencia (Referencia 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100). 🛈
