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=0.00372 (0.00145 - 0.00950), b=3.09 (2.87 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.6 ±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): Very high vulnerability (90 of 100).
