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=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.9 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
