Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 1.3 - 2.8, mean 1.7 (based on 21 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00525 (0.00432 - 0.00638), b=3.20 (3.14 - 3.26), in cm Total Length, based on LWR estimates for this species (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.5   ±0.52 se; Based on food items. Resilience (Ref. 69278 ):  Low, minimum population doubling time 4.5 - 14 years (K=0.08-0.12; tm=7-9; tmax=19; Fec = >10,000). Prior r = 0.38, 2 SD range = 0.19 - 0.73, log(r) = -0.97, SD log(r) = 0.33, Based on: 2 M, 6 K, 4 tgen, 2 tmax, 8 Fec records Vulnerability (Ref. 59153 ):  High vulnerability (63 of 100) . Price category (Ref. 80766 ):   Low .
