In a past blog post, we explored the liabilities of foreign species entering new water environments and how they disrupt existing, long established ecosystems. Invasive marine species are a significant problem in North America's Great Lakes and many other major bodies of water around the globe goby fish are just adding to that problem. Though the appearance and composition of sagebrush communities vary greatly across the west, the one thing they all have in common is an overstory of sagebrush plants of the genus Artemisia.The sagebrush steppe and shrubland communities are iconic. Sagebrush ecosystems cover vast stretches of western North America and cover more area than any other type of rangelands on this continent.

Often, as we pilot a Deep Trekker ROV close to the lake bed or attempt to pick something up with the grabber, goby fish will inevitably be found swimming nearby.Goby fish are native to rivers and estuaries of the Black and Caspian sea basins. One of the most notable features of the goby fish is a sucker used to hold onto rocks and coral.We have encountered this species many times during expeditions in the Great Lakes: exploring shipwrecks in Lake Huron, diving in the waters of Lake Ontario, holding search and rescue demos in Lake Erie, and venturing through the surf on Lake Michigan. There are over 2000 different variations of this species, originating from the family Phylum Gobiidae. One of the largest freshwater catfish species in North America.Today, we are going to focus on an aquatic species that has become extremely common throughout North America's Great Lakes: goby fish. For example, most of the food crops grown in the United States, including popular varieties of wheat, tomatoes, and rice, are not native to the region.Report a Non-native Species Recent Discoveries Have an Aquatic Pet You No Longer Want. Not all non-native species are invasive.

Their migration, combined with the inadvertent introduction of other non-native species, bring great concern in both environmental and economic points of view. This is the largest issue with advancing invasive species as they initially disturb, disrupt, and threaten to destroy established healthy ecosystems.This competition for food and habitat real estate are having a negative impact on the Great Lakes. Goby fish have since rapidly spread among the other lakes.The primary ecological liability associated with goby fish in the Great Lakes is competition for food and habitat among the native fish. Clair River, just north of Windsor. They were first identified in North America in the late 1980's found in the St.
