Pond Clearing and Medication Disinfection Methods for Aquaculture Ponds

After the dealkalization treatment of cement ponds, carry out pond clearing and disinfection promptly. Soak with quicklime at 100--150g/m³ or bleaching powder at 10g/m³ for one week, then drain the pond water and replace it with clean water. In routine management, every 10--15d, splash the entire pond with quicklime at 10g/m³, or bleaching powder at 1g/m³, or trichloroisocyanuric acid (strong chlorine essence) at 0.2-0.5g/m³, using the three in rotation. If the water is alkaline, use bleaching powder more frequently; if the water is acidic, use quicklime more frequently. At the same time, mix drugs such as oxytetracycline and sulfonamides into the feed for oral administration, using each drug for 3--5d, and rotating them once every 20--30d.
