Get to Know Myo IMNV Disease in Vannamei Shrimp and Its Characteristics
Myo disease was first discovered in Brazil in 2002. This disease is classified as malignant and deadly in vaname shrimp, with a mass mortality rate reaching 70% of the total shrimp stocked in ponds.
While in Indonesia, this disease was first discovered in 2006, precisely in one of the ponds in Situbondo Regency. Since then, research has been carried out on this shrimp disease.

So what exactly does Myo IMNV disease look like in vannamei shrimp, and what are its characteristics?
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.

Affected by IMNV
1. Shrimp Body Turns Pale
The body of vaname shrimp attacked by myo disease will gradually turn pale. While in healthy and normal shrimp, the body color tends to be transparent.
2. Muscle Color Turns White
The muscles in vaname shrimp will turn white like milk. This color change can also be seen in the body segments of shrimp infected with IMNV disease.
3. The Lower Section of the Abdomen until the Shrimp’s Tail Turns Red

The most easily recognizable characteristics of vanamei shrimp infected with IMNV are the lower segment until the shrimp tail turns red, similar to cooked shrimp. This is because all the existing networks in it have died.
