Estimates based on models

Preferred temperature (Ref. 123201): 5.4 - 19.1, mean 17.2 °C (based on 50 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00636 - 0.01435), b=3.13 (3.01 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 4.2 ±0.2 se; based on diet studies.

Generation time: 54.9 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (tm=14-24; K=0.02).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (35 of 100).
