Estimates based on models

Preferred temperature (Ref. 115969): 0.2 - 3.8, mean 2.4 (based on 409 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00200 (0.00116 - 0.00344), b=3.16 (3.01 - 3.31), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.4 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.35; tmax=8).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).
