Golden Mussels (Limnoperna fortunei) are an aquatic freshwater/brackish invasive bivalve species first discovered in California"s Sacramento-San Joaquin Delta (Delta) on October 202 4. This discovery is the first known occurrence of golden mussel in North America and was likely introduced to California
via ballast water from a commercial ship traveling from an international port.
Now that Golden Mussel are present in the Delta, they can be easily transported via trailered watercraft to areas that have not yet been invaded.
