Invasive species: Round Goby Description: Frog like raised eyes Black spot on dorsal fin Dorsal fin may be tinged green Body mostly slate gray, mottled with black to brown spots Thick lips Single scallop-shaped pelvic (bottom) fin Habitat Map The Round Goby have spread across all five the great lakes. In some areas, the fish have reached a density of more than 100 fish per square meter. It is native to the Black and Caspian seas in eastern Europe. They were first spotted in North America in 1990, in the St.Clair River. They are believed to have been brought here from ballast water of ships from Europe. They are invasive because; they compete with native bottom dwelling fish for food. They threaten the several species in the Great Lakes Basin. The Round Goby have reduced the population of sport fish by eating their eggs and and young ones. Also by competing for food.Researchers believe that the Round Goby is also connected to the botulism type E outbreaks in the Great Lake's fish and fish …show more content…
It’s thought that the the bird was more widespread in Canada before the the clearing of the forest in the 1800s. The most recent population estimate counted for 20 to 30 pairs of birds, and the population is still at a low level, and shows no sign of rising. The main reason that they are endangered is because of the continuing forest loss in Ontario. Residential and agriculture also has a negative effect on sensitive wildlife like the Acadian Flycatcher. The Acadian Flycatcher is protected under the federal Migratory Birds Convention Act. The Acadian Flycatcher is also listed under Ontario's Endangered Species Act, 2007, which protects the species from being killed, harmed, or
One species in particular, the Round Goby (Neogobious Melanostomus), is particularly harmful. This is a freshwater fish that originated from the Europe and Asia area, mostly residing in the Caspian and Black seas. The round goby was most likely introduced into this area by accident. It was brought over by ships traveling in the ocean to the Great lakes region. The first big outbreak of the round goby was found in Lake Michigan, with large amounts now found in Lakes Huron and Erie. Round gobies have only been noticed in the Great Lakes Region since about 1990. By 1994 they were found in many bays and rivers outside of Cleveland. Most of the goby sightings have remained in the Midwest.

The zebra mussel is a small freshwater mussel, this species was originally native to the lakes of southern Russia. Since their first appearance in American waters in 1988, zebra mussels have spread to a large number of waterways, including Lake Simcoe in the Great Lakes region and the Mississippi, Cumberland, Ohio, Tennessee, Michigan, Colorado, and Arkansas Rivers. Unfortunately, the invasion of the Zebra Mussel continues. For instance, in 2009 the Massachusetts Department of Conservation and Recreation confirmed that zebra mussels had been found in Laurel Lake in the Berkshires. That same year, the Minnesota Department of Natural Resources announced that live zebra mussels have been found in Pelican Lake, Minnesota.
Every day many species are slowly becoming either endangered or extinct and recently an endangered bird species called piping plovers, started nesting on Revere Beach. What would seem as a miraculous discovery, many are averse to their new inhabitants on the beach. Many Revere residents are complaining because the piping plovers now occupy parts of “their” beach. But in the article “Revere Beach should welcome the piping plover” The Editorial Board believes that the presence of the piping plover could be greatly beneficial to the city of Revere and I certainly agree. What led me to select this particular article is my concern for the many endangered species in the world like the piping plover. Human hands have led many species to become endangered
The population almost went extinct in 1980 but now they fly freely throughout the southwestern part of the United
Invasive species do not only affect other species in their ecosystem, but also cost the United States more than one hundred and twenty million dollars each year in damages (“Cost” par. 2). Invasive species come in all different forms, and all have a negative impact on the environment. These species can come into a new area without being detected at first, but as time goes on their effects can soon be seen. Efforts are being made to prevent these invasive species from destroying fish population and habitat, but in order to be successful they need to be done on a much larger scale. In order to protect Wisconsin's waters, which are already infected with many invasive species that cause great damage to our bodies of water, more actions need to be taken. It is vital to remove all invasive species from Wisconsin’s waters because it will improve fish habitat, native fish population, and water quality.

Fuller, P.J. Schofield, M.E. Neilson, A.J. Benson, and J. Li.). The grass carp is a species that is easily recognized while on the water or near the water. Silver on the sides that darkens towards the top of the fish that runs the entire length of the fish. “The dorsal fin origin is anterior to the pelvic fin origin and it has a short caudal peduncle” (Nico, L.G., P.L. Fuller, P.J. Schofield, M.E. Neilson, A.J. Benson, and J. Li.). The grass carp is typically the smallest in size in comparison to the first three carps. Weighing in at average of fifty pounds. In the past the grass carp species has been introduced to United States waters for the control of biological vegetation. “This species was first imported to the United States in 1963 to aquaculture facilities in Auburn, Alabama, and Stuttgart, Arkansas. The first release of this species into open waters took place at Stuttgart, Arkansas, when fish escaped the Fish Farming Experimental. However, many of the early stockings in Arkansas were in lakes or reservoirs open to stream systems, and by the early 1970s there were many reports of Grass Carp captured in the Missouri and Mississippi rivers.” (Nico, L.G., P.L. Fuller, P.J. Schofield, M.E. Neilson, A.J. Benson, and J. Li). The life expectancy for the grass carp is five to nine years of age. The grass carp is an aquatic vegetarian,
marine, either threatened or endangered. Under these terms species could no. longer be hunted, collected, injured or killed. The northern spotted owl falls under the more serious condition of being endangered. Also, the bill forbids federal agencies to fund or carry out any activity that would threaten the species or its habitat. It is the latter part of the bill that causes the controversy.
Luckily, as the years grew Californians started to find sea otters roaming out in the water again. Slowly but surely the population was growing in these recovering areas, but the southern sea otters (Enhydra lutris nereis), also known as California sea otters, were listed as threatened in 1977 under the Endangered Species Act. (Carswell) There are a number of reasons for why sea otters have come close to extinction.
As Canada is spread over so much area, it has many different climate zones, and a wide variety of animals in each zone. Recently, due to mining, pipelines, trapping for food and sport, and failure to preserve some forestland, many species of animals in Canada have become extinct. These include the blue walleye, sage grouse and greater prairie chicken. The woodland caribou and the marten are two of several other species that are threatened.
Species of fish in streams and lakes in the Hudson Plains include northern pike, walleye, and brook trout.
Invasive species do much more harm than just to people. They can destroy jobs for some people, a very good example of this is the decline of trout in Lake Superior .... ... middle of paper ... ..."
Back in 1904, There was a guy named Jack Miner that started a Migratory Waterfowl Refuge. This was a place for ducks to migrate. It was located in Kingsville, Ontario, Canada. In 1931, It was established in the United states, and in 1936, In canada to continue the legacy of Jack Miner. The jack Miner foundation was one of the most popular migration places for ducks. When spring came here in the United States, The ducks would all go back up north to canada to this Refuge. (“The Jack Miner Migratory Bird
