Freshwater mussels are one of the most imperiled animal groups in North America, with 30-40% of species extinct or listed as vulnerable in the last 100 years. Their decline is driven by drought, warmer water temperatures, pollution, and exotic species. The loss of native freshwater mussels (NFM) reduces nutrient recycling, habitat for aquatic organisms, food sources for animals, and water quality. The ramifications of introducing non-native fish, such as common carp (Cyprinus carpio), are well-studied. Almost nothing is known about the extent to which common carp, one of the eight most invasive fish species worldwide, disrupt the life cycle of NFM. To address this gap, we examined to what degree common carp consumed two NFM, the California floater (Anodonta californiensis, CF) and Western pearlshell (Margaritifera falcata), in the Bear River, Wyoming. In 2023, we collected stomach contents from 102 carp between 300 and 900 mm total length. Thirty-one percent contained freshwater mussels, predominately CF. This is the first documentation that common carp consume NFM, and the information has the potential to conserve native mussels by limiting direct consumption and improving abiotic conditions for these species. We suggest further investigating how native mussels can be conserved by managing common carp.
