- How orders drive production planning
- Where plant management ends and sales begin
What this project is
Fish processing turns a variable raw material into consistent products: fillets, frozen blocks, smoked fish, canned fish, or ready meals. Raw fish varies by species, size, freshness and season, and the plant must turn that variation into products that meet specifications. A plant system tracks the flow: raw material received by batch, production by line and product, finished stock by product and batch, and dispatch against orders. Yield, the proportion of raw weight that becomes saleable product, is the key measure of how well the plant is performing.
Traceability is a legal and commercial requirement, not an extra. A finished product batch must be traceable to the raw material batches it came from, and raw material must be traceable to vessel and landing where the chain supports it. That traceability enables recalls: if a raw batch is found to be unsafe, every finished product containing it can be identified. The system should maintain batch links through processing, including where batches are mixed, with the mixing recorded rather than hidden.
Core features
- Raw material intake by species, batch, weight and supplier, with quality checks
- Production records by line, product and batch, with inputs and outputs
- Yield tracking by product, raw batch and shift, showing where material is lost
- Quality checks at key stages, with results linked to batches
- Finished stock by product, batch and cold store location
- Order-driven production and dispatch planning
How it is built
- Map the plant flow first: intake, processing lines, packing, cold storage and dispatch
- Build raw intake and production records, then finished stock
- Add yield tracking and quality checks, then order-driven planning
- Test batch traceability with a mock recall, checking that finished products can be traced to raw batches
- Pilot on one product line for a month, comparing system yields with manual figures
Technology considerations
Batch mixing is the data challenge. Processing often mixes raw batches, and finished batches may contain material from several raw batches. The system needs a practical batch genealogy model: finished batches linked to all raw batches they contain, in proportions where known, so a recall can find every affected finished batch. Yield measurement needs consistent definitions too: raw weight at intake versus after gutting versus after filleting are different bases, and yield figures are meaningless unless the basis is stated.
Production data capture must fit plant conditions: wet, cold, fast-moving lines. Simple entry, barcode scanning and machine data where available beat detailed forms that staff cannot complete at line speed. Cold store location tracking matters for dispatch: finished stock that cannot be found in a large cold store delays orders and risks picking the wrong batch.
For the first version, run one product line for a month: raw intake, production, grading, finished stock and yield, with a mock recall traced from finished product back to raw batches. Plant managers judge the system on yield honesty and recall speed. A system that traces one line's batches and explains its yield, by batch and shift, is ready to cover the rest of the plant.
Challenges to plan for
- Batch links lost when raw batches are mixed without recording
- Yield figures that cannot be compared because the weight basis differs
- Finished stock that cannot be located in cold storage at dispatch time
- Quality problems discovered after dispatch, with no batch trace to contain them
Who it is for, and its limits
This suits a fish processor, a seafood company or a cooperative with processing facilities. It fits plants where yield, traceability and order fulfilment drive profitability. It does not fit a small smokehouse with occasional production, and it is not a sales system: it tracks production to finished stock, sales follow from stock and orders.
A plant system does not improve yield by itself. Yield improves when the plant can see where material is lost and act on it. Costs vary with plant size and line count, so confirm with a quote after the plant flow is mapped.
Frequently asked questions
What is yield?
Saleable product weight divided by raw material weight, for a product and batch. Yield varies with raw quality, product specification and processing skill, and is tracked to show where material is lost.
How does traceability work in processing?
By linking finished batches to the raw batches they came from, including mixing. A recall of a raw batch identifies every finished batch containing it, and vice versa.
Why does weight basis matter for yield?
Because raw weight changes through processing: gutting, filleting and trimming all remove weight. Yield must state its basis, or figures from different stages cannot be compared.
Can the system handle a mock recall?
It should be tested with one: pick a raw batch, find every finished batch containing it, and check the result against manual records. A system that cannot do that quickly fails its traceability purpose.
How are orders used?
Open orders by product drive production planning and dispatch, so the plant makes what is sold and dispatches the right batches against the right orders.
