Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5313   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00372 (0.00221 - 0.00624), b=3.12 (2.98 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245 ). Trophic level (Ref. 69278 ):  4.5   ±0.59 se; based on food items. Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100). Fishing Vulnerability (Ref. 59153 ):  Very high vulnerability (90 of 100).
