Estimates based on models

Preferred temperature (Ref. 115969): 22.5 - 27.5, mean 26.3 (based on 184 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.03236 (0.01300 - 0.08052), b=2.89 (2.71 - 3.07), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Resiliens (Ref. 120179): Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).
