Round GobyNeogobius

melanostomus

Created By: Nate Green

Name of species: Neogobius malanostomus

Common name: Round GobyKingdom: AnimaliaPhylum: ChordataClass: Actinopterygii (ray-finned fish)

CLASSIFICATION

The Round Goby was introduced to the great lakes from Europe and Asia in 1990

It was introduced by accident due to the transfer of ballast water from international ships

Today it can be found in the great lakes and many northern lakes.

From There to Here

Distribution Map

The Round Goby affects people through the effect they have on fish

The goby eats some of the native species and cause problems for fishermen

They also eat fish that people eat such as Sculpin and Perch

Effects on Humans

The Round Goby is very aggressive and highly territorial as well as very competitive for food, shelter, and spawning areas.

Due to this, the fish prey on our native population of mottled sculpin and logperch which greatly reduce the number of those sculpin and perch

Not only do they eat those fish but they eat the eggs of all the fish in the lakes

Effects on ecosystem

The Round Goby is so successful because it is very aggressive

It is able to eat fish of its same size and can eat the eggs of fish that normally eat the goby

It is also so successful since it had almost the same climate in Eurasia so it did not have to adapt

Very Successful!

Some attempts have been put into place to track the spread of this species but not much has been done to stop it

If the Round Goby stays it could mean a rough future for many fish in the great lakes

What about the future?
