What it is
Arrival condition affects how broodstock should be assessed and managed. Injury, transport stress, water mismatch and infection can look similar. Keep quarantine separate while the responsible professional investigates.
Signs to watch for
- Damage to the shell or appendages.
- Weak movement or abnormal posture.
- Poor feeding, unusual behaviour or new deaths after arrival.
Common causes
- Handling or transport problems.
- Unsuitable receiving water or an abrupt water change.
- Pre-existing illness or a biosecurity breach.
How to confirm the cause
- Match the consignment to source, transport, quarantine and screening records.
- Check receiving-water readings and arrange a professional examination and appropriate diagnostic samples.
What to do immediately
- 1
Keep the consignment in its designated quarantine system; do not mix it with cleared broodstock.
- 2
Ask the broodstock technician to assess animal condition, water and handling history promptly.
- 3
Use dedicated equipment and record feed response, injuries and losses by consignment.
- 4
Do not apply a chemical bath, antibiotic or invasive procedure by guesswork. Arrange urgent health support for worsening signs.
Prevention: your practical checklist
- Agree receiving and quarantine procedures before shipment.
- Keep source documentation and health-screening scope traceable.
- Train staff in gentle handling and water matching.
When to call an expert
- Escalate immediately for deaths, severe weakness or breathing distress.
- Get health advice before moving or using any animal with unresolved signs.
Farmer questions
Does an SPF document remove the need for quarantine?
No. Specific pathogen free (SPF) refers to a stated pathogen scope and controlled history, not protection from every disease or from new exposure. Follow the applicable quarantine plan.
Can I move the better-looking survivors?
Not as an improvised rescue. Appearance alone does not establish health. Keep the batch identity and obtain a professional movement decision.
Should I use an arrival bath from an old manual?
Do not copy a bath or dose without current, species-appropriate professional direction. A historical manual is not a prescription for this consignment.
