Muskegon River, Michigan, U.S.A. and brought to the Central Michigan University (CMU) Vivarium in July 2020. This video represents tank 5 of 6 in replicate 3 of 10 in a controlled experiment examining Round Goby behavior in relation to Fatmucket mussels. Interactions between invasive fish like Round Goby and freshwater mussels may be important due to the obligate relationship between freshwater mussels and native host fish during a parasitic mussel life stage known as glochidia. Glochidia attach to the gills and bodies of host fish before metamorphosis into juvenile mussels, and female mussels of some species utilize lures that resemble prey items to attract potential host fish for glochidial attachment. Disturbance by invasive fish like Round Goby may lead to premature release of glochidia, failure to attach to proper host fish and potentially subsequent failure to metamorphosize, resulting in reduced reproductive success for individual mussels.
