Estimates based on models
Preferred temperature (Ref. 123201
): 5 - 6.2, mean 5.6 °C (based on 30 cells).
Phylogenetic diversity index (Ref. 82804
= 1.0020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100).
