Estimates based on models

Preferred temperature (Ref. 123201): 26.1 - 28, mean 27.3 °C (based on 118 cells).

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

Bayesian length-weight: a=0.00631 (0.00362 - 0.01099), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.7 ±0.5 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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

Catégorie de prix (Ref. 80766): Very high.
