THE IMPACT OF NUTRIA (Myocastor coypus) AS AN INVASIVE SPECIES AND ITS POSSIBLE DISTRIBUTION IN WASHINGTON STATE By Ryan Kruse A Thesis Submitted in partial fulfillment of the requirements for the degree Master of Environmental Studies Round Goby (Neogobius melanostomus) is of one of Ontario's most unwanted invasive species.Round goby was first discovered in 1990 in the St. Clair River near Windsor, Ontario.
Although the round goby (Neogobius melanostomus) has become established throughout the Laurentian Great Lakes, information is scarce on spatial variation in round goby growth between and within lakes. Gobies are the only natural predators of the invasive and harmful zebra mussel. The goby is changing the population dynamics of many species in ways which we do not yet understand, but continued research aims to predict and prevent its negative impact. Invasive species that have reached the Great Lakes in ballast tanks of oceangoing ships may be costing the regional economy in the U.S. about $200 million a year, American researchers said. Description: Small bottom-dwelling fish. 2 Time series of sampling for round goby in tributaries of 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. Round goby (Neogobius melanostomus) in Baltic Sea is an invasive species, which over the past decade spreads rapidly. Our purpose was to develop potential
1 Potential mechanisms of impact from the secondary invasion of round goby to tributaries of the Laurentian Great Lakes and to species at risk of extinction Fig. Although the round goby (Neogobius melanostomus) has become established throughout the Laurentian Great Lakes, information is scarce on spatial variation in round goby growth between and within lakes. Water snakes also have experienced a population boom since the introduction of the round Goby. Ecological Society of America …
A water snakes main source of food is now the Goby. Competes with and preys on native species (NAS Database). ... economy or even human health.
They are the small soft-bodied fish that are causing big changes in the lakes. The Round Goby is an invasive species of euryhaline bottom-dwelling goby in the Gobiidea family inhabiting freshwater and marine ecosystems. Concerns: Round gobies are aggressive feeders and can find food in total darkness. Including widespread occupation of inshore habitats with cover especially plants or rocky rubble. Federal government websites always use a .gov or .mil domain. Reduction in fish host) Fig. The economic and environmental costs incurred by these invasions amount to more than $200 million each year in the Great Lakes region alone. J Kotta, K Nurksa, R Puntila, H OjaveerShipping and natural environmental conditions determine the distribution of the invasive non-indigenous round goby Neogobius melanostomus in a regional sea. The fish is believed to travel by the ballast water in ships from the Black and Caspian seas in Europe to the Great Lakes in North America.

Laurentian Great Lakes the round goby is considered a non-native, introduced, invasive species due to its rapid spread and negative effects on ecosystem equilibrium and economy.
