Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00692 (0.00401 - 0.01194), b=3.14 (2.99 - 3.29), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 4.2 ±0.73 se; based on food items.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
