Great Lakes Fishery Commission - Asian Carp Asian Carp Four species of Asian carps, bighead carp, silver carp, black carp, and grass carp, are threats to Great Lakes fisheries. Recent peer-reviewed risk assessments for bighead carp and silver carp, and grass carp indicate that the Great Lakes are at substantial risk from these three species. All four Asian carps grow to large sizes approaching or exceeding 100 lbs and four feet in length. All four Asian carps were imported to North America to assist with pest control in aquaculture facilities, and have since escaped into the wild. 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.

WWF In the time is takes you to read this page, one of our planet’s unique species will become extinct. By this time tomorrow, a further 150–200 will have disappeared forever. And by this time next year, over 50,000 more. This alarming rate of extinction is 100-1,000 times, and perhaps even 11,000 times, greater than the expected natural rate. One in four of the world’s mammals are now threatened with extinction in the near future. By and large, the cause of this decline is human activities.
