Estimates based on models

Preferred temperature (Ref. 115969): 11 - 21.2, mean 18.8 (based on 40 cells).

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

Bayesian length-weight: a=0.01514 (0.00592 - 0.03870), b=3.00 (2.77 - 3.23), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

устойчивость к внешним воздействиям (Ref. 120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).
