EHP Control in Shrimp Farming

In the dynamic world of shrimp farming, combating Enterocytozoon hepatopenaei (EHP) demands a comprehensive strategy at every stage of production. Let's delve into the refined methods of EHP control, optimized for search engines and crafted to enhance visibility.

Hatchery Vigilance: A Shield Against EHP Intrusion

Ensuring the purity of inputs is paramount. Employing Polymerase Chain Reaction (PCR) screening on Brood Stock and their feeds erects a robust defense. A meticulous Sanitation and Disinfection Protocol, reinforced by Sodium Hydroxide (2.5%) and Chlorination (40 ppm active), ensures a formidable barrier against pathogens. Potassium Permanganate serves as an additional oxidizing agent, fortifying the defense. The utilization of pathogen-free feeds, coupled with stringent processing techniques such as sterilization and pasteurization, further bolsters the fortress. Regular PCR analyses at various stages validate the integrity of the hatchery environment.

Nursery Nurturing: Cultivating Resilience

Nurturing shrimp in the nursery phase demands precision and foresight. Small, lined ponds optimize management efficiency, while an effective Central Drainage System ensures seamless operations. Ample storage capacity and reservoir ponds provide a buffer against fluctuations. Quality underground water sources enhance the environment. Employing NaOH (2.5%) and acidified chlorine for washing, along with a controlled feeding protocol, maintains a pristine environment. Post-PCR migration to grow-out ponds at the optimal time ensures a smooth transition. Lorica, a functional feed, reinforces shrimp health during this critical phase.

Grow-out Guardianship: Constructing a Stronghold

Designing grow-out ponds requires meticulous planning. Optimal pond size, shape, and layout are critical for efficient management. A robust Central Drainage System and sludge pit facilitate waste removal. A tight, compact pond bottom, coupled with lining, minimizes pathogen reservoirs. Adequate aeration, strategically positioned for efficient sludge removal, promotes a healthy environment. Reservoirs with access to underground water sources offer stability. Soil analysis, including PCR for EHP spores, guides targeted interventions. Disinfection of pond bottoms with CaO or NaOH (2.5%) elevates pH levels to disrupt EHP spores, followed by treatment with acidified chlorine. Regular soil testing ensures ongoing vigilance.

Remedies: Strengthening Defenses

EHP requires a multifaceted approach. Products safeguarding the hepatopancreas provide critical protection. During white gut outbreaks, strategic interventions such as water exchanges, altered feeding regimes, and gut supplements mitigate effects. Phytobiotics and probiotics offer natural solutions to control pathogens. Regular use of prebiotics and probiotics fortifies the microbiota balance. Adherence to strict biosecurity measures minimizes risk.

Controlling EHP: A Persistent Endeavor

EHP control presents challenges, but proactive measures yield results. Ploughing CaO into pond sediment disrupts EHP spores, raising pH levels to deter their proliferation. Patience is paramount as the soil stabilizes, returning to normal pH levels. Persistence is the key to successful EHP control.

Armis ensure the prevention of EHP entry or re-entry into farms by implementing stringent biosecurity measures: Conduct thorough PL and broodstock inspections, enforce quarantine measures, and ensure disinfection of incoming water and pond bottoms between crop cycles.

Armis as a solution for functional feed. Given that EHP infects the gut, addressing it effectively can be achieved by integrating Armis into the feed regimen.
