Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00456 - 0.02295), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (tm<1).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
