Invasive Asian Carp Threat in the Great Lakes.

Tyler Lantiegne

Asian carp, a fish introduced to the United States to control algae in catfish farms, could set up a population in the Great Lakes from a very small number of fish. According to research from Professor Cuddington of the University of Waterloo, the probability of a successful population being established increases with the addition of just 20 fish into the Great Lakes. While Asian carp have successfully established themselves in rivers connected to the Great Lakes, they have yet to move into the Great Lakes. It is expected however, that it is only a matter of time before they move into the Great Lakes due to suitable habitat. Asian carp are large fish who require a lot of food, and reproduce very quickly. These are traits of a invasive species that will be dangerous to native fish because they will out-compete the native species. A possible idea drafted to take care of the population was to take out juveniles from the lakes. This article is interesting because it discusses a hypothetical fisheries-related problem that could happen in the near future.

One thought on “Invasive Asian Carp Threat in the Great Lakes.”

  1. Thank you Tyler for sharing this very relevant and important issue for fisheries and the ecosystems. As Alaskans, invasive species and the problems that come with them are not the first things that come to mind when we think of the human impacts to the marine ecosystem. However, in recent years invasive tunicates have been detected in southeast Alaska, with huge implications for the ecosystem and for mussel and oyster farms.
