Estimates based on models
Preferred temperature (Ref.
123201): 21.1 - 26.1, mean 23.8 °C (based on 118 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.3 se; based on size and trophs of closest relatives
Generation time: 0.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (K>1).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
