The control and management of Asian carp in North America is an issue that numerous state and federal agencies have been trying work out ever since the first case of Asian carp being in the waterways of North America. Asian carp are a very difficult species of fish to manage and control because of their fast reproduction rate and that there are no predators in the North American waterways to reduce numbers. These fish are damaging native fish's food sources and habitat. More recently, Asian carp are threatening to invade the Great Lakes which would cause drastic economic and ecological problems. The fight for control of Asian carp is an ongoing battle and one that needs to be solved before it's to late.
Asian Carp should be prevented from entering the Great Lakes because they are destroying the ecosystem in that area. They are a negative contribution to the lakes because they are eating all of the plankton needed for the native fish to survive, which in turn will create a mass starvation among all the fish in the area. The Asian Carp are also a hazard to boaters, as they are capable of jumping out of the water and knocking into fishermen. They can take over an area quickly and never leave because they have no predators, they come in massive swarms, and they breed fast. There are seven types of Asian carp, but only two of these types, the bighead carp and the silver carp, are considered a threat at the moment.

There is a great big debate over whether the Asian Carp should be considered a menace and about what we should do about them. Grass, Bighead, Black, and Silver Carp are all Asian carp species. According to Keith Lawrence of the Messenger-Inquirer, Carp are being made into fertilizer, and fish oil, as well as being sold to Asia as food products. However, the New York Times say that the Carp could easily put an end to the $7 million dollar fishing industry in the Great Lakes. Aside from economic reasons for keeping or eliminating them, the main reason to stop them from spreading is the fact that they threaten to collapse the entire ecosystem if they get out of control.
The Asian carp pose a serious threat to the economy of Michigan and neighboring states as well as the natural environment. If the government does not act quickly then these terrifying fish will invade the Great Lakes. Asian carp were first imported to the United States from Southeast Asia in the 1970’s in order to filter pond water in Arkansas. They are actually three different species of carp, Black carp, Silver carp, and Bighead carp (www.nwf.org/Wildlife/Threats-to-Wildlife/invasive-Species/Asian-Carp.aspx). Silver carp can grow up to thirty-nine inches and sixty pounds.

It is the action of dragging large nets across the ocean floor trying to pick up fish. This act causes the ocean floor to be disrupted and other sea creatures to be bothered. Dr. Les Watling, Professor of Zoology at the University of Hawaii stated that, “Bottom trawling is the most destructive of any actions that humans conduct in the ocean.” (Dr. Watling) Keeping a tight rein on the quantity of fish that can be caught will help to save many species. In spite of the fact that some fishermen may suffer the loss of some of their income, in the future this will help fish to become easier to catch and be more plenteous.
If we do not take action all modern day marine life will die off and primitive organisms will once again, rule our oceans. Industrialization is a major contributor to the more evolved marine organisms dying off. From over fishing to over dosing our oceans in nutrients, it seems we’re trying to kill off all evolved marine life in our seas. Overfishing is a huge factor we must consider. Over fishing occurs when marine species are caught faster than they can reproduce.
Animals that have been moved from one area to another area that they are not indigenous to are considered invasive or non-indigenous species. These species usually do damage to the environment by attacking crops, animals, and even humans. Some species are bio hazardous and impact the environment by spreading bacteria, viruses, and diseases. The Environmental Protection Agency, or EPA, has taken extreme measures to make sure that whenever ships come in for trade, that extra luggage, being the organism, does not tag along. The EPA takes such measures because once an invasive species population gets started, it is almost impossible to control it; however, the start of a population takes time.

The most direct effect from trawl fishing is scraping of the seafloor which causes destruction of plants and other non-living things that live on the seafloor(Agardy). This also limits the potential food for other plant dwelling under water creatures.
