Field sampling to quantify the microbiome native freshwater mussels

Images of field sampling to quantify the microbiome of four species of native freshwater mussels in a side channel of the Upper Mississippi River: (a) sampling location in West Newton Chute, Pool 5, (b) supplies needed to take microbiome samples, (c) sampling the hemolymph (fluid analogous to blood in vertebrates) of a threeridge mussel for microbiome analyses.
