Estimates based on models
Preferred temperature (Ref. 123201
): 2.1 - 11.1, mean 6.1 °C (based on 371 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5020 [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
): 4.5 ±0.80 se; based on food items.
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Assuming semelparity and tm>10).
Fishing Vulnerability (Ref. 59153
): Very high vulnerability (90 of 100).
