Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01549 (0.01240 - 0.01934), b=3.04 (2.98 - 3.10), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.27 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
