Estimates based on models
Preferred temperature (Ref.
123201
): 14.7 - 23.4, mean 17.3 °C (based on 37 cells).
Phylogenetic diversity index (Ref.
82804
): PD
50
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00647 - 0.03228), b=3.05 (2.85 - 3.25), 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 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153
): Low vulnerability (10 of 100).
