Natural History Of Zebra Mussels

Areas of water including butts or ponds and sand pits must be securely fenced off or covered.

Today, what once was a scenic lake is covered in chest-high weeds. “ Boaters and fisherman enjoy going to Lake Bridgeport during the summer. But in the summer of 2013 the boat ramps were unusable so the number of residents going to the lake dropped. There are dead fish floating to the shoreline as well as many other wildlife animals. The lake tested positive for Zebra Mussel larva, which is shell like creatures that are very sharp and stick to boats, anchors and docks. The Mussels are very dangerous for the lake environment, but they also eat bacteria so they could help the lake water clear up. If no water is drained out of Lake Bridgeport then the residents of Eagle Mountain Lake and Lake Worth could possibly run out of drinking water.

More than 24 billion gallons of untreated sewage waste and storm water are pumped into the lakes annually. Pollution is increasing as well, due to the cottage development, where people enjoy spending their summers relaxing. For many years, the lake habitats have been affected by pollution and habitat destruction. The market for fish is tremendous; so much so, that we have depleted our fishing resources, and have had to market on invasive species.

     Colonization by zebra mussels has devastating ecological impacts on native bivalves (Mackie, 1991; Haag et al., 1993), frequently driving them to local extinction. Zebra mussels readily, perhaps preferentially, settle on native bivalves and eventually cover them over. They filter the water so efficiently that they can lower the amount of suspended food organisms below levels needed to sustain native unionids.

Some examples include the zebra mussel, sea lamprey, and Asian carp. The zebra mussel first came to the great lakes by traveling in the ballast water of a transoceanic vessel. Over the years, it has spread into the entire great lakes system. They are very dense with contaminants, which causes predators to stray away from them and not digest them. The zebra mussel has had many negative impacts on the ecosystem. A zebra mussel can attach themselves firmly to any solid object, which has caused water intake and discharge pipes to clog. Some other impacts include suppressing native mussels, over clarifying the water, and stripping water from various plankton that native fish eat. Sea lamprey are another invasive species in the great lakes. A sea lamprey is an eel like fish that sucks bodily fluids from other fish. They have traveled to the great lakes on their own by swimming up the Hudson River. They have contributed to the collapse of the whitefish and lake trout fisheries. Some prevention actions have been put in place and include chemical treatments of spawning

First of all, Zebra mussel disrupt the food chain. In the Great lakes, zebra mussels eat the plankton that small, native fish need to survive. Consequently, this hurts the native fish and the larger fish that feed them.

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

Eurasian milfoil or Myriophyllum spicatum is an aquatic invasive plant that can be found throughout the Chicagoland area and in surrounding bodies of water. This plant can be a hinderance to swimming, boating, and fishing because of their thick, tangled stems and mats of vegetation. According to the Minnesota Sea Grant, Eurasian milfoil also overcrowd a body of water which leaves little room for the plants native to the Great Lakes. One prediction is that if the Eurasian milfoil is not stopped, a reduction of biodiversity may result in Chicago and the areas surrounding it. If this was to occur, the ecosystems of the Midwest region would be significantly impacted in a negative way.

In response to invasive species threats, Ontario’s Ministry of Natural Resources, Agriculture, Food and Rural Affairs, Environment and Transportation developed the Ontario Invasive Species Strategic Plan. Its objectives are to prevent new intruders from disembarking and subsisting in Ontario, to reduce and reverse the extent of remaining invasive species and decrease its damaging impacts. Ballast water is a well-known source for the introduction and spread of aquatic invasive species in the Canadian water bodies. In response, Canada and the United States placed strict regulations governing ocean-going ships and their ballast water. For example, requiring inspection and the flushing of tanks with salt water before entering other waterways. Collectively,

In the article published by the Detroit Free Press “How do you get rid 750 trillion mussels in the Great Lakes” written by Kathleen Lavey, the author discusses how there is currently no technology that would help on a large enough scale to kill all of the invasive mussels. Lavey talks about how there are paints that contain chili peppers which muscles don’t atach to. Companies use this paint on intake pipes so they do not get clogged with muscles. Lavey also discusses 060Bio which a piece of foam that is infused with copper and zinc ions which muscles find unsavory. They place these on boats, that way boats don’t get infested with muscles and move them around the lakes. There are many different ideas out there but they don’t have a method that

At the bottom of the Missouri's streams lives the Lampsilis siliquoidea mussels where it lives out its life cycle. How it lives it's brilliant life cycle is first by luring a smallmouth bass over to it by copycatting the movement and the appearance of a Tartars fish tail which is actually the skin of the mussels which has over time evolved. Once the bass notices the lure and strikes the lure the muscle spews out a white cloud into the bass's mouth and gills which happen to be thousands of larvaes where they will live off the bass for nutrients. Its also safer for them to transition from larvae into juvenile mussels. After a couple of weeks the young mussels abandon the bass dropping leaving the basses unharmed and unaware of what happened making

Recently zebra mussels from Black Sea, stowed away in ballast water ships, invaded North American waters, they blocked the water lines of factories, nuclear power plants in the regions of Great Lakes. Just after the arrival of Christopher Columbus’s ships in America in 15th century resulted in worldwide exchange of disease, crops and animals in the 20th century practice of ships using water as ballast helped to unite the formerly diverse world’s harbours. Similarly, air transport allows the spread of insects and diseases that would not easily survive

The brook floater, scientifically known as Alasmidonta Varicosa, is a type of mussel that lives in flowing waters, like streams and rivers, in the U.S. and Canada. While, very important to our aquatic ecosystems, this mussel species is predicted to become extinct because brook floaters are sensitive to pollution and aren’t protected very well. Their population has been slowly decreasing since 2002 and they will be gone soon if nothing is done to stop it.

The only thing we can do is to make sure that we are not transporting quagga mussels. Boat owners need to clean, drain, and dry their boats or have them professionally decontaminated. During the summer, self cleaned boats need to dry for 7 days before entering another body of water. The fall and spring recommendation is 18 days, and 30 days in the winters (or 3 days in below freezing temperatures.) Several states are already taking action against quagga infestations. Idaho, for example, has boat inspection stations set up at almost every major road entering into the state. Laws require that boaters must stop at one of these stations on their way to recreational waters. Utah, in conjunction with Idaho, spends $2.6 million per year to contain quagga mussels. To put this amount in perspective, that is the same amount the United States government spends on presidential vacations alone! Since 2009, when Idaho launched its inspection program, nearly 300,000 boats have been inspected. Over 200 of those boats were contaminated with over 400 labeled as high

With the increasing amount of disturbed habitats, invasive species could soon become the leading cause of ecological degradation (Soulé & Orians, 2001).  Invasive species can alter habitats in a number of ways.  Changes in the physical structure of the land are the most visually obvious.  Examples include narrowing stream channels, reducing sand supply to dunes, and stabilizing surfaces such as mudflats, and each invasive species goes about these changes in their own way.  For instance, the burrowing activities of Australian isopods cause the banks of tidal channels to collapse, leading to the widening of channels and the loss of vegetated salt marsh (Cox, 1999).  On the other hand, Japanese mussels that have invaded the San Diego area are stabilizing mudflats.  Although reaching Southern California in the 1960s,
