Aquaculture biosecurity refers to the measures taken to protect fish farms from the introduction and spread of diseases and pests. Effective biosecurity protocols include controlling access to farms, disinfecting equipment, and monitoring the health of fish stocks. Regular water quality checks, quarantine measures for new stock, and disease surveillance systems help minimize risks. By preventing outbreaks of diseases like vibriosis or infectious pancreatic necrosis, biosecurity plays a vital role in sustaining fish populations and reducing reliance on antibiotics. This also ensures the long-term health of aquatic ecosystems and the economic viability of the aquaculture industry.
