Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  4.0   ±0.4 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <10). Fishing Vulnerability (Ref. 59153 ):  Moderate to high vulnerability (48 of 100). Price category (Ref. 80766 ):   Low .
