Estimates based on models

Preferred temperature (Ref. 123201): 3 - 7.6, mean 4.4 °C (based on 1911 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [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).

Trophic level (Ref. 69278): 3.2 ±0.37 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100).
