Estimates based on models

Preferred temperature (Ref. 123201): 17.5 - 23.6, mean 20.2 °C (based on 66 cells).

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

Bayesian length-weight: a=0.00263 (0.00138 - 0.00502), b=3.21 (3.04 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.0 ±0.5 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Preliminary low fecundity).

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