5.1.6. Water management

• 30cm water level is maintained for first 30-40 days with lab lab.
• It is increased to 50-100 cm when fish grow bigger and supplemental feeding starts.
• Pumping may be necessary to keep the pond water at a higher level than outside.
• Monitor dissolved oxygen at 6-8 AM and 2-4 PM. Aeration becomes necessary if oxygen levels drop to 1 ppm.
