they came in big sea vessels from Europe in their balist tanks and as they pumped water out they were so small they flew into the lakes
a round goby is a type of fish that is a invasive species in all lakes in and around Michigan
they are basically making the native species in the Great Lakes extinct.... :(
Anything you want it to man!!
Round goby was created in 1814.
yes except if its in a new area other than the Great Lakes and the Black and Caspian sea (its origin) and if it is in a new place, call USGS
Fresh water(invasive spieces to the great lake)
there are 2 theories. some people think they came in ballast water tanks but some people think that it was brought here on purpose because the Round Goby eats the Zebra Mussel(another invasive specie) and the Zebra mussel was in the Great Lakes first so people think that someone brought them here to take care of the zebra mussel invasion but as it turns out, the Round Goby became invasive as well and sorta helped the "zebra mussel invasion".
The Round Goby eats the native sculpin and logperch's eggs so they are almost extinct.
yes.
snapper allaigators
you mean how do they? they still do and they affect it badly by eating the native fish's eggs so they won't be able to reproduce.
The Goby Fish is native to Eastern Europe. They can be found in the Caspian Sea and the Black Sea.
