Estimates based on models
Preferred temperature (Ref. 123201
): 7.8 - 15.4, mean 11.5 °C (based on 31 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00152 - 0.00688), b=3.22 (3.05 - 3.39), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (19 of 100).
