Estimates based on models
Preferred temperature (Ref.
123201
): 25.1 - 28, mean 27.1 °C (based on 232 cells).
Phylogenetic diversity index (Ref.
82804
): PD
50
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00476 - 0.02897), b=2.88 (2.66 - 3.10), 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
): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153
): Low vulnerability (10 of 100).
