Biosecurity refers to the precautions taken to keep particular pathogens out of shrimp cultures. In shrimp farming, biosecurity includes sanitation, personal hygiene, pond preparation, water screening, disease-free seed stocking, and the prevention of disease carriers from entering the area.
Biosecurity is very crucial in farming to maintain a disease-free environment:
• Use LDPE and high-quality nylon crab fencing to manage carriers, or burrowing agents.
• Use bird fence with ideally red and blue fiber threads to keep birds and their droppings away.
• Sanitization dips like Potassium Permanganate (KMnO4) solution at entry and exit areas should be provided.
• 4 layers of filtration of source water by 20, 40, 60 & 80 mesh.
• Disinfection of water with 30 – 60 ppm of active chlorine.
• To prevent cross-contamination, clean farm tools and materials on a regular basis using potassium permanganate or any hypochlorite solutions.
• Farming area should be clean and maintain personal hygiene of the farm workers.
• Regulation of movement of farm workers in and out of the farm
• Outsiders who could be disease carriers should not be allowed or subjected to preventive protocol before giving access to visit the farm premises.
