4. TEST THE SEED FOR DISEASE• Shrimp seed may have pathogens like White Spot Syndrome Virus (WSSV) andMonodon Baculo Virus (MBV). Viral related disease can cause mass mortality ofshrimp in tambaks.• Collect and pack about 100 seed in a seed bag and send to a shrimp health laboratoryfor disease testing.• The result should be negative for WSSV by PCR test. Similarly it should be negativefor TSV if it is relevant in the farming area.• If you do not have a laboratory facility nearby, use dot blot test kit (eg. Shrimple TMtest kit) to test for WSSV. If double bands appear on the kit then reject the seedbatch. If only single band appears on the kit then the batch can be selected.• Also test for MBV by simple microscopy (staining method). If MBV infection ismedium or very high, then do not select the seed batch.Presence of Disease: Double bandNo disease: Single bandBetter Management Practices for Tambak Farming in Aceh | 28
