Fish Farmers

⮚ Raise & Reinforce Pond Dykes - In areas where rainfall is intense, increase dyke heights by at least 30 cm above expected peak water levels;

⮚ Install & Maintain Effective Drainage Systems - Desilt pond inlets and outlets to prevent waterlogging; Construct emergency spillways lined with concrete or stones to guide excess water safely away from ponds;

⮚ Secure Inlet & Outlet Structures - Install wire mesh screens (5 mm – 10 mm) on inlet and outlet pipes to prevent fish from escaping.

⮚ In areas prone to floating debris, clear blockages frequently to prevent overflow.

⮚ Lower Water Levels Before Heavy Rains - In high-rainfall regions gradually reduce pond water levels by 20–30%;

⮚ Prevent Erosion & Siltation - In areas with loose soils, reinforce pond walls with gravel or stabilized soil to prevent erosion.

⮚ Emergency Preparedness & Backup Plans - Stock fish cages in deep ponds as an extra precaution for valuable species.

Livestock farmers

⮚ Once there a dry period (for a week), cut and preserve grass as hay or silage;

⮚ For any unusual strange insects or disease on crops, report to the nearest Agricultural Office in your area.
