| Scientific Name |
(Limnoperna fortunei) |
| Classification and Permitting Level |
1 - Prohibited Aquatic Nuisance Species |
| Species Description |
Golden Mussels are small (<2 inch) freshwater bivalves that can be brown, yellow or olive in color. They can be distinguished from native mussels by the presence of byssal threads, small hair-like structures used to attach to surfaces. They may be confused for invasive zebra or quagga mussels. |
| Preferred Habitat |
Typically found attached to shaded hard surfaces, but may also attach to soft surfaces in lower densities. |
| Reason for ANS Designation |
Alter the food web by feeding on planktonic communities that can negatively impact water quality and the ecosystem. Golden mussels can foul equipment and pipes in power and water industries, which can have significant economic costs. Once established, control is very difficult and costly. |
| Place of Origin |
Golden mussels are native to eastern Asia and were first documented in the United States in 2024. The initial introduction was found in the port of Stockton, California. |
| Stopping the Spread |
When taking equipment out of a lake or stream, remove all plants and mud and drain all water prior to leaving. Allow the equipment to dry completely, rinse with 140°F water for 10 seconds of contact. |
