Why are round gobies bad?
Why are round gobies a problem? The round goby can displace native fish from prime habitat and spawning areas. Round gobies eat the eggs and young of other fish species. Have a competitive advantage over other species because of the ability to survive in poor quality water.

Can you eat a goby?
Currently, Goby species are primarily identified by their surface patterns; thus, they are easily misidentified as non-toxic and edible mudskippers or other species by individuals without special training.
Do round gobies eat zebra mussels?
In the food chain’s opposite direction, round gobies eat harmful zebra mussels and quagga mussels, two other invasive species. The mussels sharply reduce the plankton food base and cost billions of dollars to remove from water-intake structures. Gobies are among their few predators.
Can you eat gobies?
“And as part of the food web, they too are being eaten—smallmouth bass and birds are eating gobies and are growing.” But this brings up a concern. As bottom dwellers, round gobies hang out where the contaminants are.

Why are Round gobys an invasive species in Michigan?

Round gobies also have a competitive advantage over native species due to a well-developed sensory system that allows for enhanced water movement detection and the ability to feed in complete darkness.
How are Round gobys bad for the environment?
Adult gobies take over prime nearshore spawning sites and aggressively prevent use by native species. Long-term impacts are expected to include declines in native species populations. N. melanostomus has a well-developed lateral line which may give it a competitive advantage over native species feeding in turbid waters.
