What it is
Transport adds handling and water-quality risks to an existing seed batch. Arrival losses need review of both pre-dispatch condition and the journey. They do not automatically prove a hatchery disease or a buyer’s mistake.
Signs to watch for
- Weak seed, damaged bags or deaths on arrival.
- Unexpected journey delays or temperature changes.
- Packing, departure or arrival records are incomplete.
Common causes
- Seed were unsuitable for dispatch or handled poorly.
- Packing, oxygen provision or water conditions did not suit the journey.
- Delays, rough handling or receiving-water mismatch added stress.
How to confirm the cause
- Match batch quality and health records to packing, timings, journey and arrival observations.
- Have trained staff assess seed and bag/receiving water safely; contact the laboratory for a suitable sampling plan if needed.
What to do immediately
- 1
Contact the hatchery and receiving technician promptly and preserve bag and batch identity.
- 2
Assess seed and water and follow a stage-specific receiving plan; do not dump transport water or weak seed into a clean pond or tank.
- 3
Record arrival time, observations, water readings and losses accurately.
- 4
Isolate unresolved suspect lots and obtain a professional movement decision. Do not treat transport stress with an improvised product mix.
Prevention: your practical checklist
- Agree a validated packing and receiving plan for the expected journey.
- Record quality, packing conditions, timings and destination.
- Plan delays, communication and trained receiving staff before dispatch.
When to call an expert
- Rising losses, severe weakness or oxygen concerns need immediate technical assessment.
- Unresolved quality or health questions need a release decision before stocking.
Farmer questions
Is there one safe seed count per bag?
No. Stage, quality, water volume, packing method, oxygen, temperature and journey time all matter. Use a validated plan rather than a universal bag-count recipe.
Do arrival deaths prove infection?
No. Packing, journey, receiving conditions and pre-existing health all need investigation. Keep evidence and seek assessment instead of assigning blame from one observation.
Should transport water go into the receiving pond?
Do not introduce it automatically. Receiving and waste-water handling must follow the biosecurity and acclimation plan.
