Estimates based on models

Preferred temperature (Ref. 123201): 8.4 - 17.2, mean 11.8 °C (based on 99 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00063 (0.00029 - 0.00138), b=3.18 (3.00 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100).
