Fish Paddle Tails and Curly Tails for the Perfect Goby Imitation
Round gobies have forever altered the ecology, and the angling landscape, of the Great Lakes and connected waterbodies. Since their discovery in the St. Clair River in 1990, these invasive stowaways from the Black and Caspian seas have become key players of their local food webs. Indeed, round gobies are among the few fish that consume undesirable zebra and quagga mussels, themselves transported to the Great Lakes within the same ballast tanks that harbored the first goby colonists. At the same time, gobies have become established as integral components of many gamefish diets.
