Lake Michigan Quagga Mussel Density

Invasive quagga mussels are so entwined and influential in Lake Michigan’s food web that they are an essential first line of study. Scientists on the R/V Lake Guardian in 2015 measured the density and biomass of quaggas all across the lake using traditional sampling methods like PONAR grab samples, as well as new and innovative techniques like underwater videos. Cooperative Science and Monitoring Initiative (CSMI) researchers achieved a more complete insight into life on the lake floor than ever before. Learn more:
