Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00048 (0.00025 - 0.00091), b=3.28 (3.12 - 3.44), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.7 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).
