- 01 Water before feed — watch the pond first Fish show you the unit is drifting before a crash. Read oxygen, temperature, and behaviour, then decide whether to feed.
- 02 Stock what the water can carry; buy healthy seed Overstocking hides as slow growth and disease. Cheap, weak fingerlings rarely catch up. Match density to air, water, and labour.
- 03 Feed for conversion, not for leftover pellets More bags do not mean more saleable fish. Excess feed pollutes water, raises oxygen demand, and wastes money.
- 04 Prevent disease with water, space, and calm handling Most outbreaks were weak water, crowding, dirty kit, or stress for days. Medicines cannot permanently cover weak daily work.
- 05 Harvest gently, then ice without delay Quality is lost in the last hours on the farm. Small lots, shade, and ice close to 0°C beat a rushed pile …
- 06 A batch without records is a business risk Write source, feed lots, water, treatments, and harvest the same day. Memory will not isolate a problem when a buyer asks.
