Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00331 - 0.01203), b=3.15 (2.97 - 3.33), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref. 120179):  высокий, минимальное время удвоения популяции до 15 месяцев (tmax=3; Fec=50-720).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
