Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6270 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.0 se; based on diet studies.

Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (tmax=5; K=0.26).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).

Preiskategorie (Ref. 80766): Unknown.
