TUBENOSE GOBY'S Threatens Ecosystem

Invasive Species causes harm and TUBENOSE GOBY'S is to blame

Invasive TubeNose Goby's must be taken care of ASAP

The Tubenose Goby is an invasive species which is dangerous because they can


  • effect the chemical makeup of the water
  • availability of resource
  • alter the food web
  • compete for resources
  • invasive species negative to the biodiversity
  • incredibly costly The annual cost to take care of invasive species in the U.S is roughly 120 billion dollars per year
  • It's been estimated that it costs about 5% of the entire world's economy to control invasive species.

Information about the Tuberose Goby

  • The Tuberose Goby (Proterorhinus semilunaris) is native to rivers and estuaries of the Black and Caspian sea basins but later was declared as invasive when they found it in locations in the Great Lakes.
  • Researchers believe that in 1990 Tubenose goby were brought to North Americain the ballast water of ocean-going ships because of how frequently interlake shipping occurs and with the vast quantities of ballast water being transported.

The Tubenose Goby eats bottom-dwelling fish and competes with them for food. The fish may also eat and compete for food with other fish species that live near shore areas of lakes and rivers. The Tubenose Goby is not yet known to have any major impacts on the ecosystem but many researchers strongly believe it will in the long term.
