Largemouth Bass Virus in Virginia
by the Virginia DWR
Largemouth bass virus (LMBv) is a disease that impacts several fish species but only appears to cause death in some largemouth bass. In fact it is the only known virus to cause mortality in largemouth bass. LMBv was first discovered in Lake Weir, Florida in 1991 and the first reported fish kill occurred four years later at Santee Cooper Reservoir, South Carolina. As it spread throughout the southern United States, LMBv was responsible for other largemouth bass die-offs in the late 1990’s. However, in many reservoirs LMBv did not result in significant die-offs but only led to a decrease in survival and growth rates. When such decreases in survival and reduced growth rates occur, anglers catch fewer quality-size largemouth bass – bass greater than three pounds. The good news is that these impacts from the virus outbreak are normally short lived and largemouth bass fisheries recover in about 3-6 years as individuals build up a resistance to the disease.
