Underwater cannon may help protect Great Lakes Wall Street Journal (12/30) Biologists plan to use a seismic gun to chase invasive round gobies from several Lake Michigan reefs.
Overview 
The goby is a bottom-dwelling fish that has great potential for causing impacts on Great Lakes fisheries. Originally the round goby and the tubenose goby were introduced into the St. Claire River in 1990, probably via contaminated ballast water of transoceanic ships.
Round goby are thriving in the Great Lakes Basin because they are aggressive, voracious feeders which can forage in total darkness. The round goby takes over prime spawning sites traditionally used by native species, competing with native fish for habitat and changing the balance of the ecosystem. The round goby is already causing problems for other bottom-dwelling Great Lakes native fish like mottled sculpin, logperch and darters. Goby can also survive in degraded water conditions, and spawn more often and over a longer period than native fish. Unfortunately, they have shown a rapid range of expansion through the Great Lakes. Many of the characteristics of the round goby invasion parallel that of the Eurasian ruffe. Photo Credit: David Jude, Center for Great Lakes Aquatic Sciences
