Lives in clear vegetated lakes, quiet pools and backwaters of creeks and small to large rivers (Ref. 205, 10294). Solitary, lurking hunter on other fishes as well as on ducklings, muskrats, and snakes. Oviparous, spawn in spring as the ice melts (Ref. 205).

Some experts believe that some form of copulation happens during breeding of this species. The female turns on her side to expose her abdomen to the male who then swims against her in a forceful movement. Aftewards, the female takes a rest and deposits her eggs in the sand. This whole activity is presumably repeated one more time (Ref. 205). Other experts believe otherwise, that only a simple and simultaneous discharge of gametes happens during breeding (Ref. 205).

Estimates based on models

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5157 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00490 (0.00371 - 0.00647), b=3.08 (3.02 - 3.14), in cm total length, based on LWR estimates for this species (Ref. 93245).

Nível Trófico (Ref. 69278): 4.5 ±0.3 se; based on diet studies.

Generation time: 6.4 (5.5 - 7.1) years. Estimated as median ln(3)/K based on 25 growth studies.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (K=0.07-0.15; tmax=30).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (67 of 100).

Categoria de preço (Ref. 80766): Unknown.
