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=0.02291 (0.01064 - 0.04934), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
