Estimates based on models

Preferred temperature (Ref. 123201): 11.9 - 13.5, mean 12.6 °C (based on 6 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00813 (0.00366 - 0.01807), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Generation time: 7.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).

Preiskategorie (Ref. 80766): Medium.
