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=0.01514 (0.00869 - 0.02637), b=3.12 (2.97 - 3.27), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.34 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (tm<1; multiple spawning per year; Fec=20-150).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
