Estimates based on models

Preferred temperature (Ref. 123201): 14.7 - 23.2, mean 18.6 °C (based on 31 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00089 (0.00036 - 0.00222), b=2.98 (2.76 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 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 vulnerability (10 of 100).
