Estimates based on models

Preferred temperature (Ref. 115969): 8 - 12.9, mean 9.7 (based on 19 cells).
Índice de diversidade filogenética (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00723 - 0.03808), b=3.05 (2.85 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.4   ±0.5 se; based on size and trophs of closest relatives
Resiliência (Ref. 120179):  Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
