Asian Carp in the Great Lakes

Asian Carp where brought to America in the 1970’s because of their ferocious appetites, to keep algae and other matters out of ponds on catfish farms. Asian Carp average a full-grown length of five feet, and can surpass one hundred pounds. They breed and populate, and grow very quickly. Asian Carp are adversely affecting their un-natural environments by starving out native pond and river inhabitants. They have been slowly but surely migrating up the Mississippi River since their introduction to the Georgia portion. Their imminent arrival to the Great Lakes of Michigan has become a serious concern. This would be an issue because the Great Lakes are currently home to more than 43 federally protected species of fish. An invasion by Asian Carp

There were Asian Carp found in a water mass in one of the Great Lakes. Imported from Asia, the sliver carp, will out compete native species in the Great Lakes for food. This would ruin the ecosystem in the Great Lakes because the carps will out compete the species that are native to this lake for food causing the native species to die off. In the Great Lakes commercial and sport fishing is an industry that is worth billions yearly. The silver carp that was found in the great lake could have gotten there many different ways. On is that is swam through the electric barrier that prevents carps from entering the water way. Another is that it could have been on about and carried past the barrier. Lastly, it could have been placed in the lake by

As well as pollution, invasive species are damaging the lake ecosystems and food chains, made fragile by pollution and overfishing. The introduction of a new species throws off the balance of food chains. Some common invasive species include the sea lamprey, Asian carp, and zebra mussels, among many others. Zebra mussels have dramatically influenced and affected stable food chains by reducing the amount of zooplankton and phytoplankton. This presents a problem, as fish mostly feed on the drifters, and so they go hungry and die, leaving no food for larger fish to prey on. In addition to underwater disruption, it affects us as well, but only slightly. Plankton and algae especially are the most productive aquatic producers of oxygen, and by the decreasing population, we lose oxygen as well. The sea lamprey is also a problem, though it is not so influential to ecosystems as the zebra mussel.

Introduced species are seldom a positive addition to an ecosystem as they cause great stress and harm to the populations of native species. Many introduced species become invasive as they have no natural predators in their new environment, therefore they thrive, and crowd out all other animals. Some examples of invasive species in Ontario waters include the round goby, zebra mussels, eurasian ruffe, goldfish, northern snakehead, rainbow smelt, and rudd, to name a few. A great example to show how destructive an introduced fish can be is the asian carp, this species spreads very aggressively and it is considered the greatest threat to aquatic ecosystems in Ontario. These fish grow to be very large in size, up to 40 kg and 1 meter long. The asian

Another main challenge facing the Great Lakes is the threat of invasive species, specifically the Asian Carp. The Asian Carp is very dangerous to the great lakes if they were to invade the Great Lakes they would have the capability to knock out entire species of fish while having no real predators. The intrusion of this fish has the potential to ruin the lake's ecosystem altogether. Not only would it hurt the ecosystem immensely, but would drastically hurt the 7 billion dollar fishing industry in the United States. The Greats Lake Restoration Initiative has funded electronic barriers in places vulnerable to the Asian Carp, to keep the fish out of the Great Lakes. These barriers have been successful and have slowed the spread of Asian Carp in

I have noticed that there is a lot of Sea Lampreys in Lake Superior. I live in the Duluth area and I love to fish. Being a concerned resident of the area I would like to see less Sea Lampreys in the lake. I think cutting the Sea Lampreys population to little or none will help out all of the fish in the area and will also bring a lot more fishermen to the lake. I hope that you can agree with me and I hope that we can come to an agreement on how to stop the Sea Lampreys from killing all of the other fish in the area.

Now days times have changed. You can no longer enjoy the things you once could. It has become dangerous to waterski or to even enjoy a boat ride down the river due to the Asian carp. These fish are startled easily by boats, and small watercraft. They can jump ten to twelve feet out of the water causing damage to boats and injuring humans. I have heard of people getting cuts from the fins, black eyes, concussions, broken noses and jaws, and even knocked unconscious from this species of fish. Not only are these Asian Carp causing physical damage, they are wreaking havoc on the ecological system. The main concern from the Asian Carp is the dangerous effects that it is bringing to our ecosystem. As an avid fisherman, this is of great concern to me. This will not only affect me as a fisherman, but also possibly hunters, bird watchers, boaters, even jet skiers and water skiers are

The black carp inhabits large river/lake habitats, and is native to many Pacific drainages located in eastern Asia. It is also known as snail carp, Chinese black carp, Chinese roach, black amour, or black Chinese roach. They appear blackish brown with blackish grey fins with an elongated/laterally compressed body. On average, they grow to 3+ feet and weigh an average of 33 pounds. They are known to live for 33 years. Currently, they are in research facilities in the United States, but have not been spotted in the wild. However, if they were to get into the wild, this would heavily disrupt the mussel/snail populations, downsizing them. In addition to this, other native fish, turtles, birds, and vertebrates such as raccoons, otters, and muskrats would be affected via competition for food. They can also host many pathogens, allowing infection of many other

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. The Great Lakes Fishery

Species have been invading the Great Lakes for a very long time. “Scientists estimate that there are more than 185 invasive species in the Great Lakes today.” One of the species that invade the Great Lakes is the Round Goby. This animal usually feeds on fish eggs, Yellow Perch, Bass, and Walleye. The Round Goby is an invasive species because it kills other species, or it can make them extinct. Another example of invasive specie is Quagga Mussel. The Quagga Mussel usually sits in lakes or oceans, building up over a long period of time, this leads to millions, and millions

Alien species on the humber watersheds are a major ecological issue for the environment because they prevent other native species from living/growing in their natural habitat. Alien species do this by taking up physical space that native species need , preventing native species from reaching their food and water and spreading disease. The humber watershed is affected in two different ways: native species and the overall ecosystem of the watershed. invasive species on the humber watersheds have a major threat to the biodiversity of our waters,wetlands, and marshes. These organisms that originate from different ecosystems pose a great threat to our ecosystem because coming to our ecosystem their natural predators can no longer keep the population's growth rate under control and that causes an increase in population because of that devastating effects on native species, habitats, and ecosystems may occur. There are reports that over 185 non indigenous species were found Ontario’s Great lakes. Some invading species that been found in the Great lakes are the following;

Water is an important resource and weather agent in our world, and the Great Lakes Region has an intimate relationship with water. The region was shaped by glaciers long ago and continues to be shaped by flowing surface water today. Groundwater is very pure in the area, which allows for plants, animals, and humans to thrive there. Migration into the area can be related to the groundwater found there. Human use of the water results in man-made structures, water flow alteration, and changes in water quality. Water is very influential in the Great Lakes Region.

But unfortunately, this hasn’t been working as well as it should- an entirely new invasive species has been found in lakes in Minnesota. Starry Stonewort, an algae, produces many of the same negative effects as Eurasian Water Milfoil or Zebra Mussels. It coexists very well with Zebra Mussels, and is actually stronger than Eurasian Water Milfoil, choking it out in competition for food and space. It isn’t picky about growing conditions, and is very hard to remove by hand. A biological control agent has not yet been discovered for the Starry Stonewort, so at this point effort needs to be focused on preventing the spread (Marcotty,

Despite this, because of this it’s long snout, rows of sharp teeth, and armored body has made it be considered a “trash fish” by fishermen. It’s appearance also lead people to believe that it was eating far more desired trophy fish. From then on for nearly 50 years the fish was hunted and killed, being driven out of it’s natural habitat and forced to retreat. This continued up until the 1980’s when scientist were able to debunk these myths and start conservation efforts. These efforts have helped protect and reintroduce the Alligator Gar back into it old habits. The recent reintroductions of the Alligator Gar has started to raise questions if they could be used to fight the the Asian Carps ever expanding numbers.

The Great Lakes provide 20% of the world's fresh water source and are one of the most profitable areas in the world. If we as a species want to benefit from the water supply we have, The Great Lakes must be protected from threats such as invasive species, and allowed to flourish. Although there a slough of invasive species, there are also proper methods for minimizing and dealing with the invasive species and pollutants in the Great Lakes.
