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=0.01096 (0.00493 - 0.02437), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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