Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00912 (0.00607 - 0.01371), b=3.07 (2.95 - 3.19), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.3 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (tm=2-4).

Fishing Vulnerability (Ref. 59153): High vulnerability (57 of 100).

Preiskategorie (Ref. 80766): Very high.
