The best information available provides evidence that if an invasion of Asian carp into the Great Lakes were to occur, it would probably take many years for the population to become problematic, based on the history of Asian carp invasions, models of invasive species and the size of the Great Lakes. Because of the threat these invasive carps hold for the Great Lakes, the commission is actively working with partner agencies to prevent their introduction and establishment. They were first noted in the Okanagan Valley in , as was their rapid growth in population.
Description: The extremely high abundance of bighead and silver carp has caused great concern because of the potential for competition with native species for food and living space.
