Estimates based on models
Preferred temperature (Ref. 123201
): 2.9 - 3.3, mean 3.1 °C (based on 12 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5635 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00730 - 0.03605), b=3.03 (2.83 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (18 of 100).
