Estimates based on models

Preferred temperature (Ref. 123201 ): 15 - 22.8, mean 17.2 °C (based on 15 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00525 (0.00220 - 0.01254), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.4   ±0.6 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
