Freshwater mussels are among the most endangered animals on Earth, while marine mussel farming raises questions about invertebrate welfare at scale.
Freshwater mussel conservation is a critical biodiversity priority as these filter feeders support river ecosystem health. Marine mussel farming, if bivalves lack morally relevant experiences, may represent a relatively low-welfare-cost animal protein source. Protecting wild freshwater mussel habitats from pollution and dam impacts serves clear conservation and ecological welfare goals.
