Estimates based on models
Preferred temperature (Ref.
123201): 6.2 - 8, mean 7.1 °C (based on 8 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00206 - 0.01336), b=3.10 (2.88 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on diet studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (35 of 100).
