They disrupt the ecosystems by monotypic colonization, and damage harbors and waterways, ships and boats, and water-treatment and power plants. Ecological damage from zebra mussels in the Great Lakes region has negatively impacted the $3.4 billion commercial and recreational fishing sector, which employs more than 10,000 people in the region. Invasive species have an impact on every system here and cost more than $200 million annually in lost revenue and prevention strategies. Individual power plants and industrial facilities in the region spend upwards of $2 million annually to control them. Unfortunately, the carp have circumvented the fence on several occasions. Many times when people think of invasive species they only see them as destroying the native ecosystem, but the invasive Round Goby has also positively impacted the Lake Erie ecosystem in a way that some native species have been declared to no longer be endangered, such as the Lake Erie Water Snake (Nerodia sipedon insularum) (Bunnell et al., 2005). “Asian carp” is a general term used for four species of carp—bighead, silver, black, and grass—that originated in Asia and were imported to the southern United States in the 1970s to support aquaculture. This invasive species affixes to nearly any submerged hard surface, from rocks to piers to boats. Dropping usage and values of beaches and beach property But in recent years, millions of invasive mollusks, each the size of a human fingernail, have complicated the task of pumping that water to residents. Regional Collaboration, Foundations for Future Restoration Actions, Food Web Modeling to Support Risk Assessment of Asian Carp in the Great Lakes, Strategy to Prevent Invasive Crayfish Impacts to the Great Lakes Basin: The Invasive Crayfish Collaborative, Forecasting the Bioeconomic Impacts of Aquatic Invasive Species (AIS). In conclusion, high genetic variability, large numbers of founders, and multiple founding sources likely significantly contribute to the risk of an exotic species introduction's success and persistence. They foul beaches, harm fisheries, clog water infrastructure, and lead to the regional extinction of species. However, Asian carp are threatening to take hold in the Great Lakes by swimming u… How did all this pollution accumulate in the Great Lakes? Many non-native species have been introduced into the Great Lakes since the early 1800s, either accidentally or intentionally. 0. Asian Carp has wrought profound economic and ecological damage in the ecosystems in which it has taken root. Zebra mussels filter large quantities of plankton from the water column, depriving fish and other aquatic life of a valuable food source. Wisconsin Department of Natural Resources, $3.4 billion commercial and recreational fishing sector, James F. Lubner/University of Wisconsin Sea Grant Institute. Sea Lamprey. Unfortunately, the damage caused by invasive species often goes beyond the ecological impacts. How they got here. The range for invasive species could increase as the area around Lake Michigan warms with climate change. They have no natural predators in North America and each female produces roughly five million eggs over the course of her lifespan. The plankton-shredding flea is just one of many intruders into the Great Lakes, which host more invasive species—more than 180— than any other freshwater system on the planet. More than 180 non-native species have entered the Great Lakes, and a new species is discovered every 28 weeks on average. Since then, they have spread rapidly throughout waterways in the Great Lakes basin, Mississippi River, and other U.S. watersheds and have been spotted in more than 30 states and Canada. Preventing them from ever entering is the … Shedd Aquarium has a research team that studies Lake Michigan and other bodies of water to understand and protect aquatic populations. Site Admin Once invasive species are established in the Great Lakes, it is nearly impossible to remove them. Invasive spiny water flea is eating the plankton that small fishes feed on, disrupting the food chain and ecosystem's balance in the Great Lakes. The effect of this invasive species on the Great Lakes area is far greater than you might guess from their size. Because of this, AIS present in Michigan’s waters may eventually spread to New York’s. Free from natural predators, invasive speci… In May, the self-cloning marbled crayfish clawed Michigan and regional headlines by officially becoming an outlaw. Additional barriers and monitoring efforts will be necessary to limit the spread of Asian carp and other invasive species and ensure the economic and ecological health of the Great Lakes region. Some invasive species enter the Great Lakes by hitching a ride in ballast water tanks. Some Great Lakes fish spawn in reefs that contain piles of rocks and boulders, laying eggs in the crevices. 3. The more an invasive species becomes established in an ecosystem, the more money must be spent on regulations, monitoring programs, and eradication measures to prevent severe economic and environmental impacts. The city of Lockport, a community of 21,000 residents in upstate New York, relies on the Niagara River for its drinking water. Asian carp, a large adaptable fish that was accidentally introduced into the Mississippi River watershed in the 1970s, is on the verge of entering the Great Lakes. The river connects Lake Erie to Lake Ontario and provides Lockport with more than enough clean water to satisfy demand. Some side effects of polluting the lakes are reproductive, developmental, behavioral, neurologic, endocrinologic, and immunologic effects on the human population. Since then, at least 180 invasive species, including the round goby, spiny water flea, and a close relative of the zebra mussel, the quagga mussel, have colonized the Great Lakes. This Halloween, we’re getting spooky with some invasive species that have invaded the lakes – and more species threatening to cause havoc if we don’t stop them. Along with overfishing and pollution, invasive species are responsible for the loss of 18 fish species in at least one Great Lake. One of the biggest threats to Great Lakes fisheries and the broader Great Lakes economy is the invasive Asian Carp species, which already worked its way through the Mississippi River Watershed. We quantify the economic damages of the degradation of an important ecosystem service, water clarity, caused by invasion by … Aquatic invasive species are non-native plants, animals and microscopic organisms that have a profound negative impact on an aquatic ecosystem or human activity. Introducing a species into a new environment may have a variety of outcomes.   Web Site Owner: Thus, the most cost-effective strategy for curtailing invasive species is prevention. This allows zebra mussels to rapidly colonize ecosystems at the expense of native mollusk species. Invasive species—like zebra mussels and round gobies—have forever damaged the Great Lakes. The economic and environmental costs incurred by these invasions amount to more than $200 million each year in the Great Lakes region alone. Thousands of communities like Lockport are now burdened with the costs of the zebra mussels’ presence.
