Estimates based on models
Preferred temperature (Ref. 123201
): 11.5 - 19.6, mean 16 °C (based on 10 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00288 (0.00149 - 0.00560), b=3.19 (3.01 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±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
): Moderate vulnerability (37 of 100).
