Disease Prevention Calendar

Disease control starts before stocking with drying, liming, inlet filtration, crab fencing, bird control and pond preparation.

Avoid stress peaks caused by sudden salinity change, low oxygen, overfeeding or poor handling during sampling.

Keep visitors, tools and nets controlled between ponds. Cross contamination often spreads faster than farmers expect.

Escalate early when you see reduced feeding, surface swimming, colour change or unusual mortality. Early action saves crops.
