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".
Scientists believe that the round goby reached North America in the waters discharged by transoceanic ships.
Round goby was created in 1814.
a round goby is a type of fish that is a invasive species in all lakes in and around Michigan
The Round Goby eats the native sculpin and logperch's eggs so they are almost extinct.
yes.
snapper allaigators
The Goby Fish is native to Eastern Europe. They can be found in the Caspian Sea and the Black Sea.
Fresh water(invasive spieces to the great lake)
the males turn black when spawning but usually, they are green or gray!
The dragon goby is semi-aggressive, but mainly feeds by sifting organisms out of the mud. In general, like most fish, they will eat anything that fits in its mouth. A fancy goldfish can reach 10"-12" and a dragon goby can reach 24". It would seem that once the goldfish reached a large enough size, it would be safe. I would not put a 2" goldfish with a 24" goby.
clean their boats to prevent it and fish poison
They cause harm to the environment because they eat animals thar are soon to be extinct
They eat another invasive animal, the Zebra Mussel. They eat about 75 of them each day!
