Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

North America: Atlantic and Gulf slope drainages from New York to northern Mexico, and St. Lawrence-Great Lakes and Mississippi river basins from southern Quebec west to central North Dakota, and south to the Gulf. At least one country reports adverse ecological impact after introduction.

Pools, backwaters, and sluggish current over soft substrate in creeks and small to large rivers; oxbows, ponds, and impoundments (Ref. 5723, 10294).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01014 (-0.11535 - 0.13562), b=3.10420 (3.02092 - 3.18748), based on LWR estimates for species & family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.46 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4; Fec=2,000).

Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100) .

Price category (Ref. 80766): Unknown.
