Asian Carp vs the Great Lakes

The possibility of Asian squid entering the Great Lakes is a huge problem, which is expensive and time consuming to solve. US Army Engineers Corporation is currently evaluating obstacles to prevent Asian catfish from leaving the Great Lakes waters. Strategy - Possible). Currently, large fish are brought out of the Great Lakes Region using electric fences (http://www.popularmechanics.com/science/environment/natural-disasters/how-to-stop-the-carp-invasion).

The four Asian carp, big fish, squid, black bora, and glass coy are a threat to the Great Lakes fishing industry. Risk assessment of the recently peer reviewed large fish, salmon and grass suggests that the Great Lakes are subject to major risks from these three species. The main threat to Asian catfish is the competition of food resources with other fish and the ability of these intruders to outweigh the local fish. The risk of black cockroaches is not evaluated. Like other intruders, the Great Lakes Fisheries Commission thinks that preventing the introduction and establishment of Asian catfish is the only effective way to maintain valuable Great Lakes fisheries.

Asia salmon introduced in North America is a major threat to the upstream and upstream ecology, environment, economy and lifestyle of the United States, Canada and the Great Lakes Region. Asian catfish is a group of fish species containing several known invasive species and represents the most pressing potential danger for the Great Lakes ecosystem. The US Department of the Interior and the US Fish and Wildlife Service submitted to the Congress the first annual report on this issue in December 2014.

In 2012, the US Senate and the House of Representatives announced a new bill to combat the Asian catfish entering the Great Lakes by accelerating part of the "suspension of Asian Catfish Law" in 2011. Legislation provides guidance to the US Army Corps of Engineers to complete their work. A study on the method of separating the Great Lakes from the Mississippi River Basin within 18 months. In collaboration with the University of Minnesota, the US Geological Survey created an extensive report on the use of environmental deoxyribonucleic acid (eDNA) to detect waterway species. This report was compiled in 2011 after extensive field study of e-DNA positive results in Asian catfish in Minnesota waterways. The rivers under investigation are the Mississippi River and the St. However, although several cases were arrested in Minnesota in the past two years, new studies can not reexamine the existence of Asian catfish.
