Estimates based on models

Preferred temperature (Ref. 123201): 2.3 - 5.4, mean 3.7 °C (based on 812 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00210 - 0.00687), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.39 se; based on food items.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).

Price category (Ref. 80766): Unknown.
