Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00573 - 0.01590), b=3.03 (2.89 - 3.17), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Weerstandsvermogen (Ref.
120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (K=0.19-0.63(?); tmax=6; Fec > 10,000).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (45 of 100).
