Estimates based on models
Preferred temperature (Ref. 123201
): 2.3 - 8.4, mean 6.2 °C (based on 322 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.5 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
): Moderate to high vulnerability (50 of 100).
