9.2.1 Freshwater prawn brooder transport
Transport of freshwater prawn brooders Berried females collected from the natural water bodies can be transported from the collection site by keeping them individually in perforated plastic or PVC pipes or cylinders capped on both sides with pieces of netting. The pipes/ cylinder carrying brooders should be kept in the water in the polythene bags. During transit, the polythene bags are oxygenated by oxygen. For shrot distance, tanks or bins are well suited for this purpose. During long distance transportation tips or restrum and telson may be banded or capped with protective rubber tubes and transported in plactic bags filled with water and oxygen (1:1). This is to avoid physical damage to spawners and bag. Temperature can be controlled by keeping small ice bags alongside the plastic containers & keeping inside the bins/ tanks. Metabolite accumulation in the medium can be delayed by starving the animals for few hours before packing for transport. |
