Estimates based on models

Preferred temperature (Ref. 123201): 14.3 - 18.5, mean 16.3 °C (based on 72 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01230 (0.00694 - 0.02182), b=3.03 (2.87 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.8 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 to moderate vulnerability (28 of 100).

Preiskategorie (Ref. 80766): Unknown.
