Description

The round goby is a sturdy bottom goby of the family Gobiidae reaching about 25 cm but usually smaller. The stout, brownish spotted body has as a hallmark a conspicuous black spot at the rear of the first dorsal fin; like other gobies the pelvic fins are fused into a sucking disc. The species is native to fresh and brackish water of the Black and Caspian seas but is among the most successful invasive fish in the world: through ballast water and canals it has colonised the North American Great Lakes, the Baltic and western European rivers such as the Rhine and Meuse. It eats mainly shellfish, small crustaceans, worms and fish fry. The male fiercely guards the eggs. Through its aggression and numbers it displaces native bottom fish.
