Estimates based on models

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

Bayesian length-weight: a=0.00813 (0.00372 - 0.01775), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.5 ±0.37 se; based on food items.

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).
