You can split a spawning batch's settlement plates into sub-plates in the Coral Traceability Solution (CTS). You select the batch by scanning a settlement plate, then scan the resulting sub-plate fragments. You start from the Breed Coral tile.
To create a spawning batch first, see How do I record coral breeding and create a spawning batch?
Select the batch and start a split
On the Create spawning batch screen, tap Select existing batch, then scan a settlement plate that belongs to the batch. When the batch is recognised, tap Split batch.
Scan the sub-plates and save
The Scan plate fragments screen shows 'Press button on your device to scan plate fragments one by one'. Scan each sub-plate fragment; they appear in the Scanned items list. Tap Split to save the data to the CTS and create the traceability record. A confirmation notification appears.
For scanning help, see How do I choose or change my scanning method (RFID, QR or Visual ID)?
