From Conserve Wildlife Blog: New Jersey is home to at least 16 species of freshwater bivalves (freshwater mussels and clams), half of which are listed as endangered or threatened within the state. The presence of freshwater mussels within a water body is an indication of water quality so determining where they occur is important for protecting water resources within the state. In fact, the NJ DEP’s “Category One” (C1) designation for some state waterways is often based on the presence of some freshwater mussel species. C1 waters are protected from any measurable change in water quality because of their exceptional ecological significance, exceptional recreational significance, exceptional water supply significance, or exceptional fisheries resources.
