Estimates based on models

Preferred temperature (Ref. 123201): 7 - 14.8, mean 10.5 °C (based on 453 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5059 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.8 ±0.5 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Assuming tmax>10).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (47 of 100).
