Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00307 - 0.01489), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
