Shrimp farming has been a rapidly growing aquaculture business in the last decade. However, it suffers significant obstacles as a result of disease issues. Infectious agents like viruses, bacteria, fungi, and parasites can cause shrimp diseases, as can non-infectious variables such as environmental circumstances.
The white-spot disease is one of the most difficult to combat in shrimp farming. Effective management and prevention measures, including adopting biosecurity measures and disease-resistant breeds, are critical to preserving cultured Shrimp’s health and assuring the industry’s long-term viability.
Hepatopancreatic Parvo-like Virus (HPV) in Shrimp (Prawn)
Introduction to Hepatopancreatic Parvo-Like Virus (HPV) in Shrimp
Shrimps are susceptible to the extremely contagious Hepatopancreatic Parvo-like Virus (HPV), which is a significant cause of the outbreak. The virus is so called because it can harm the Shrimp’s hepatopancreas, a crucial organ in digestion and food absorption.
The HPV virus seriously harms Shrimp’s digestive tract, which manifests in symptoms like decreased appetite, lethargy, and weight loss. The virus poses a danger to the worldwide shrimp farming sector since it can, in extreme situations, result in high fatality rates. Controlling the spread of this virus requires effective management and preventative measures.
The Pathogen Responsible for Shrimp Hepatopancreatic Parvo-like Virus (HPV)
The Hepatopancreatic Parvo-like Virus, a small parvo-like virus about 22-24 nm in diameter, is the principal cause of the disease in Shrimp (HPV). This virus is responsible for considerable digestive system damage in Shrimp, resulting in symptoms such as decreased appetite, lethargy, weight loss, and even death.
What are the Signs and Symptoms of Hepatopancreatic Parvo-like Virus (HPV) in Shrimp
- Hepatopancreatic parvo-like virus (HPV) in Shrimp has several signs and symptoms.
- These include reduced feeding and poor growth rate.
- Body surface and gill fouling with ciliates may occur, and the abdominal muscles may become opaque.
- Severe infections can result in a whitish and atrophied hepatopancreas, anorexia, and reduced preening activity.
- Increased occurrences of surface and gill fouling organisms and secondary infections by opportunistic Vibrio spp. can lead to losses.
- Prompt identification and implementation of management practices can help reduce the impact of HPV on shrimp production.
- Reduced feeding and poor growth rate
- Body surface and gill fouling with ciliates, occasionally leading to the opacity of abdominal muscles.
- Severe infections may result in a whitish and atrophied hepatopancreas, anorexia, and reduced preening activity.
- Increased occurrence of surface and gill fouling organisms and secondary infections by opportunistic Vibrio spp. can lead to losses in the shrimp farming industry.
