Estimates based on models
Preferred temperature (Ref. 123201
): 1.8 - 4.1, mean 2.3 °C (based on 2932 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00170 - 0.00811), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Fec presumed to be <10,000).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
