Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00427 (0.00183 - 0.00992), b=3.04 (2.83 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.1 ±0.5 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
