Estimates based on models
Preferred temperature (Ref.
123201
): 14.5 - 17.3, mean 15.4 °C (based on 35 cells).
Phylogenetic diversity index (Ref.
82804
): PD
50
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00089 (0.00036 - 0.00223), b=2.98 (2.77 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245
).
Trophic level (Ref.
69278
): 3.5 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153
): High to very high vulnerability (75 of 100).
