What Is Myo Disease in Vannamei Shrimp?
Infectious Myonecrosis Virus (IMNV), or myo disease, attacks white shrimp and can cause substantial economic losses due to mass deaths.
IMNV virus can infect all stages of shrimp life, including post-larvae, juveniles, to adult shrimp. However, more deaths were found at the stage of young to adult shrimp.
Meanwhile, the transmission of this virus can occur in two ways, namely horizontally and vertically. Cannibalistic behavior in infected shrimp can be a way of horizontally transmitting this disease. While vertically, this virus can be transmitted from the parent to the fry it produces.
