Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00147 - 0.00981), b=3.11 (2.88 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.3 se; based on diet studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (K=0.6).
Fishing Vulnerability (Ref.
59153): Low vulnerability (23 of 100).
