Health management in Recirculating Aquaculture Systems (RAS) is critical for ensuring optimal productivity and maintaining water quality. With high stocking densities, the risk of disease transmission increases, making biosecurity measures essential. Regular monitoring of water parameters, such as oxygen levels, pH, and temperature, helps maintain a healthy environment. Additionally, preventive health practices such as vaccinations, parasite control, and nutritional management are crucial. Managing stress levels in fish and ensuring proper feeding strategies can also enhance immune function. Effective health management protocols in RAS not only ensure sustainable farming practices but also reduce the need for antibiotics, promoting healthier ecosystems.
