Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00331 (0.00148 - 0.00739), b=3.16 (2.98 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (tmax=6).

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).
