The Macroinvertebrate Lab at Valley City State University (VCSU) is heading into the third year of a State Wildlife Grant to examine mussel and aquatic insect populations within the state of North Dakota. Ten species of freshwater mussels in North Dakota are listed as a Species of Greatest Conservation Need, Black Sandshell (Ligumia recta), Creek Heelsplitter (Lasmigona compressa), Creeper (Strophitus undulatus), Deertoe (Truncilla truncata), Fragile Papershell (Potamilus fragilis), Mapleleaf (Quadrula quadrula), Pink Heelsplitter (Potamilus alatus), Pink Papershell (Potamilus ohiensis), Threeridge (Amblema plicata), and Wabash Pigtoe (Fusconaia flava). My project was to collect and summarize the data on these 10 species of mussels. In addition, the VCSU Macroinvertebrate Lab has placed Passive Integrated Transponder (PIT) tags on mussels at three different sites. We returned to those sites and used a PIT tag reader and antennae to find the mussels and record their death or survival, length, and position. An important component of this project is to disseminate this information to both the general public and other researchers. I have photographed exemplary specimens of these mussels from the various sites they have been found and am preparing data into a proper format to submit to online portals that track global species data. Our data will be summarized and made available on iNaturalist, the Global Biodiversity Information Facility (GBIF) and other online platforms.
