Estimates based on models
Preferred temperature (Ref.
123201): 28.2 - 29.3, mean 28.8 °C (based on 1221 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03548 (0.01723 - 0.07305), b=2.81 (2.62 - 3.00), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Fec assumed to be > 10,000).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
