Lake Winnipeg is Canada's sixth-largest freshwater lake [3] and the third-largest freshwater lake contained entirely within Canada, but it is relatively shallow (mean depth of 12 m [39 ft]) [4] excluding a narrow 36 m (118 ft) deep channel between the northern and southern basins. It is the eleventh-largest freshwater lake on Earth.

Invasive species have been introduced to lentic systems through both purposeful events (e.g. stocking game and food species) as well as unintentional events (e.g. in ballast water). These organisms can affect natives via competition for prey or habitat, predation, habitat alteration, hybridization , or the introduction of harmful diseases and ...

[30] Common causes of invasive species in freshwater ecosystems include aquarium releases, introduction for sport fishing, and introduction for use as a ...
