Comments: Known from lakes Zürich and Walenstadt. At present there is a homogenous population in Lake Walenstadt which spawns October - November. Fifty years ago, there were two populations, one spawning July-September and the other December-February. The winter-spawning population is said to have appeared in 1899. It has been hypothesized that displacement of spawning grounds, changes in temperature, and possibly invasion by a species from Lake Zürich resulted in a hybrid population (involving 2 or 3 species), which is now stabilizing after severe environmental problems which impacted the lake at the beginning of the 19th century (Ref. 59043).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00190 - 0.01097), b=3.13 (2.92 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).
