Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01000 (0.00517 - 0.01933), b=3.09 (2.93 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245 ). Trophic level (Ref. 69278 ):  2.7   ±0.22 se; based on food items. Resilience (Ref. 120179 ):  High, minimum population doubling time less than 15 months (tm = 0.13; tmax = 0.33; Batch Fec = 1-7;). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
