Estimates based on models

Preferred temperature (Ref. 123201): 8.8 - 22.4, mean 15.2 °C (based on 417 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00513 (0.00240 - 0.01095), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.50 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
