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=0.00501 (0.00202 - 0.01242), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.2 se; based on diet studies.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (tmax=15).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (44 of 100).
