Estimates based on models

Preferred temperature (Ref. 115969): -1.3 - 1.2, mean -0.1 (based on 18 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00646 (0.00293 - 0.01422), b=3.17 (2.97 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.1 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.24; tm=4; Fec = 4,666).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (47 of 100).

Climate Vulnerability (Ref. 125649): High to very high vulnerability (73 of 100).

Preiskategorie (Ref. 80766): Low.
