  1. Round Goby FishNeogobius melanostonius Power Point By: Keith Serio Rimsha Jalal

  2. About the Goby Fish • Common Name: Round Goby Fish • Scientific Name: Neogobius melanostonius

  3. Distribution • Native to the Caspian and black sea Eastern Europe region introduced to great lakes regions of north America • Is in ballast water discharged by transatlantic ships • First found in St. Clair river in 1990

  4. FOOD WEB

  5. Effects on people • They have several negative impacts on human and native ecology:  • Their aggressive nature and ability to become abundant quickly may allow them to out compete some of our native species for food resources and spawning habitat. They will feed on small native fish, including darters, native fish eggs and fry and lake trout.  Their aggressive feeding nature will be a nuisance to fishermen who have difficulty catching target sport fish in areas where goby are present

  6. Effects on Earth/ Habitat • They are aggressive • Reproduce rapidly • Feed on smaller native fish such as the darters, fish eggs, fry and lake trout • Eat other invasive species and some common fish  

  7. Reasons for success • The behavior of the goby has also contributed to its success. The round goby is a territorial fish that competes aggressively for food, shelter, and spawning areas. This behavior has allowed it to displace native fish, such as the mottled sculpin and logperch from some areas of the Great Lakes. • They eat large quantities of zebra mussel, a highly problematic invader species with an extremely high reproductive capacity. North American laboratory studies have shown that individual gobies can eat as many as 78 zebra mussels a day.

  8. Issues for the future • Several precautionary measures can  also be taken to further help control and slow the spread of gobies.  These include: • Inspecting live bait to ensure that no round gobies are accidentally released into fishing areas; • Discarding live bait on land, and not into the water, to ensure that no exotic aquatic life is introduced into native water bodies;  • Implementing Ballast water exchange laws that restrict and regulate the dumping of ballast water within North American waterways.
