Fragmenting (fragging) coral records that you have cut new fragments from a broodstock colony. You scan the broodstock before fragmentation, then scan the resulting fragments, and the Coral Traceability Solution (CTS) links each fragment to its broodstock. You start from the Frag Coral tile on the Home screen.
Scan the broodstock
On the Home screen, tap Frag Coral. The Frag coral screen opens with the instruction 'Press button on your device to scan broodstock before fragmentation', a Target source code toggle (C / W), an empty Scanned items list with a RESCAN button, and a greyed-out Next: Scan fragments button.
Set the Target source code toggle to C (Captive-bred) or W (Wild). This classifies the resulting fragments and decides which measurements and photos are required.
Scan the broodstock tag. It appears in Scanned items with a generation indicator (for example, 'RFID.99910231923102931 (P)' or '(F1)'), and Next: Scan fragments button becomes active.
Optionally, tap the broodstock item to add measurements or a photo.
What measurements and photos are required depends on the target source code and the broodstock generation, see What measurements and photos are required when fragging (source code C vs W)?
Scan the fragments
Tap Next: Scan fragments. You will then be asked what will happen to the boodstock with two options that records whether the broodstock colony survives the fragmentation:
Take piece: a fragment is cut from the broodstock and the broodstock colony remains intact.
Divide into frags: the broodstock is fully split into fragments, so the original colony no longer exists as it was.
For further information, see When fragging, what do 'Take piece' and 'Divide into frags' mean?
You can proceed to scan the fragments and may be required to add a photo, measurements, and/or notes for each fragment.
For scanning help, see How do I choose or change my scanning method (RFID, QR or Visual ID)?
If the photo and weight icons beside the coral are red, you must add the details, if they are green, it is ok to proceed. The Register Coral button will only display as green and be clickable once all fragments have the required photo and measurement data added (and the icons are all green).
What measurements and photos are required depends on the target source code and the fragment generation, see What measurements and photos are required when fragging (source code C vs W)?
Finalise and save
Tap Register coral. The data is saved to the CTS and a confirmation notification appears at the bottom of the Home Screen (for example, 'Batch registered!' in green), with a dismiss (×) button.
What gets saved
Each fragment is saved with a unique identifier (UID) matching its tag, the Fisher (your participant organisation), the Location (your default location), the Species and Variety inherited from the broodstock, a link to the broodstock, and a generation value set automatically (for example, 'F1' if the broodstock was 'P'). You can view it on the web app in the Product List or via the View Coral action in the mobile app.
