5.1.4. Stocking of nursery pond

• Nursery pond is stocked with three day old spawn when adequate plankton appears in it.
• For maximum survival of spawn, nurseries should have a rich crop of zooplankton preferably rotifers and cladocerans.
• A minimum of 1.5 to 2.0 ml zooplankton in 54.5 ml water is essential for satisfactory stocking of the pond.
• In well manured nurseries 1.0-2.0 million spawn has been stocked with satisfactory results, with a provision of artificial feed, at the pond culture Substation of the CIFRI.
• The stocking of a nursery pond is best done either in the morning or evening hours.
