Estimates based on models
Preferred temperature (Ref. 123201
): 6.7 - 10.1, mean 8 °C (based on 23 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00138 - 0.00659), b=3.23 (3.06 - 3.40), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153
): Moderate to high vulnerability (50 of 100).
