Recent U.S. Geological Survey studies in western Lake Erie suggest a decrease in zebra mussel numbers but an increase in quagga mussels and total mussel abundance over the last decade. (sciencedaily.com)
They found that recent decreases in critical lake nutrients, partly due to increases in invasive species such as quagga mussels, reduce the amount of Chinook salmon that the lake can support. (sciencedaily.com)
The study also found that lake trout and steelhead may fare better because these two species can switch from eating alewife, which are in decline, to bottom - dwelling round goby, another newly established invasive prey fish that feeds on quagga mussels. (sciencedaily.com)
