Aquatic Invasive Species

Aquatic invasive species (AIS) include fish, animal and plant species that have been introduced into an aquatic ecosystem (ocean, lake, river or stream) where they have not been found historically. Aquatic invasive species have been entering Canadian waters for centuries but never as rapidly as today, due to increased global trade. Every decade, some 15 AIS establish themselves in our coastal or inland waters where, in the absence of their natural predators, the most aggressive of them spread rapidly. This can, and often does, result in harmful consequences for the native species found in the natural aquatic ecosystem, by radically altering habitat and rendering it inhospitable for native species. AIS have been implicated in vast reductions or the outright extinction of indigenous fish populations across Canada and the resulting devastation of local fisheries. Concerns locally regarding impacts of zebra and quagga mussels on power generation are increasing.
