Estimates based on models

Preferred temperature (Ref. 123201 ): 13.8 - 15.9, mean 15.1 °C (based on 7 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01175 (0.00476 - 0.02897), b=2.88 (2.66 - 3.10), 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 ):  Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (20 of 100).
