What this project is
Seafood passes through many hands: vessel or farm, landing or harvest, processor, distributor, retailer. At each step, batches may be split, mixed or transformed into new products. A traceability platform records those steps, batch by batch, so a finished product can be traced back to its origin, and an origin batch can be traced forward to every product containing it. That two-way traceability is what makes recalls fast and sustainability claims checkable.
Batch identity is the foundation, and it is fragile. A batch that is split must produce child batches linked to the parent; batches that are mixed must produce a new batch linked to all parents. If those links are not recorded, traceability breaks at the first processing step, and the platform becomes a set of disconnected records that look complete but prove nothing. The system should enforce link recording at each step, and flag breaks plainly where they occur.
Core features
- Batch records for catch, farm harvest, processing and distribution, with origins and quantities
- Batch split, merge and transformation handling, preserving links in both directions
- Handover recording between parties, with quantities and dates
- Two-way traceability: forward from origin to products, backward from product to origin
- Recall support: affected products and customers identified from a batch in minutes
- Buyer and regulator views showing the chain for a batch or product
How it is built
- Map the supply chain first: parties, steps, and where batches split, mix or transform
- Build batch records and handover recording, then split and merge handling
- Add two-way traceability views, then recall support, tested with mock recalls
- Add buyer and regulator views, then reporting for certification where used
- Pilot on one product chain, from origin to buyer, checking that every link survives
Technology considerations
Batch genealogy is the technical core. The data model must support many-to-many links: one raw batch into many products, one product from many raw batches, across several processing steps. Quantities must reconcile: the total quantity out of a step should not exceed the quantity in, allowing for yield loss, and the system should flag quantity breaks. Different parties use different systems, so the platform needs practical data exchange: standard formats or simple imports, rather than requiring every party to use the same software.
Trust depends on completeness. A chain with a missing link is not a chain, and the platform should show gaps honestly rather than implying a complete chain. Access control matters too: each party sees its own batches and the chain for products it handles, while buyers and regulators see the chain for products they buy or oversee. Commercially sensitive data, such as prices, should not be part of traceability records unless explicitly required.
For the first version, trace one product chain from origin to buyer: batch records, split and merge links, handovers, and a mock recall completed in minutes. Buyers judge the platform on whether a finished product traces back to origin without gaps. A platform that traces one chain completely, with quantity reconciliation at each step, proves the genealogy model before it covers every product.
Challenges to plan for
- Batch links lost at processing, where mixing was not recorded
- Quantities that do not reconcile, hiding substitution or loss
- Parties in the chain who do not record handovers, breaking the chain
- Traceability claims made for products whose chain has gaps
Who it is for, and its limits
This suits a seafood company, a processor, a distributor or a retailer requiring traceability. It fits supply chains where buyers or regulators demand origin proof. It does not fit a direct quayside sale with no onward chain, and it is not a sustainability certification system: it tracks origin and handling, certification is assessed separately against its own standards.
A traceability platform does not make seafood sustainable or safe. It proves origin and handling, so sustainability and safety claims can be checked. Costs vary with chain length and party count, so confirm with a quote after the chain is mapped.
Frequently asked questions
What is two-way traceability?
Tracing backward from a product to its origin batches, and forward from an origin batch to every product containing it. Both directions matter: backward for buyer questions, forward for recalls.
How are batch splits handled?
A split creates child batches linked to the parent, with quantities recorded. Each child carries the parent's origin information, so traceability survives splitting.
What about mixing?
Mixing creates a new batch linked to all parent batches. A product from mixed batches traces back to every parent, which is essential for recalls.
How fast is a recall with this system?
Affected products and customers should be identifiable in minutes from a batch, rather than days of phone calls and paper records. That speed is the main operational benefit.
Does every party need the same software?
No. The platform supports data exchange in standard formats or simple imports, so parties can record handovers in their own systems and share the traceability data.
