Estimates based on models
Preferred temperature (Ref.
123201): 18 - 25, mean 21.9 °C (based on 61 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00740 - 0.03723), b=3.01 (2.81 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Nivel trófico (Ref.
69278): 2.8 ±0.25 se; based on food items.
Generation time: 4.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resiliencia (Ref.
120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (K=0.22; tmax=10, but probably greater).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (36 of 100).
