# Farmed rock lobster and other sea crawfish, live, fresh or chilled

## 1. Scope and Applicability

This PCR guides foreground data package construction for farmed rock lobster and other sea crawfish in CPC 3.0 `04322`, placed on the market as live, fresh, or chilled product. It covers aquaculture production of Palinurus spp., Panulirus spp., Jasus spp., and other rock lobster or sea crawfish taxa when the reporting operator controls hatchery, nursery, puerulus or juvenile receiving, grow-out, sea-cage, pond, tank, ranching, live holding, chilling, pack-out, or delivery operations.

Covered products include whole or declared-product-basis farmed rock lobster and sea crawfish, whether in shell or not, sold live, fresh, or chilled. The default route covers biological starting stock sourcing, hatchery or nursery where controlled, grow-out husbandry, harvest, grading, live holding or chilling, packaging, and release at the declared gate.

Excluded products are wild rock lobster and other sea crawfish, Homarus lobsters, Norway lobsters, crabs, shrimps, prawns, freshwater crayfish when not part of this CPC category, frozen, dried, salted, brined, cooked, canned, meat-only, prepared, or preserved products, biological seed sold as a separate input, and shells, molts, or processing residues modelled as separate products.

Because commercial spiny lobster and rock lobster aquaculture often relies on region-specific puerulus, juvenile, hatchery, or grow-out supply chains, a conforming dataset must show controlled aquaculture activity. Wild capture followed only by live holding, chilling, grading, or dispatch is outside this PCR.

| How long or cycle | one aquaculture production batch, grow-out batch, harvest lot, or reporting period normalized to marketable product output |
| reference_flow_link | Reference amount and product flow below |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg |
| Reference product flow | Farmed rock lobster and other sea crawfish, live, fresh or chilled `5ec1e534-2b3b-4ef7-a934-15d67185b9c7` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | species or taxon group; puerulus, postlarval, juvenile, broodstock, hatchery, collector, or grow-out stock source; culture system; farmed proof or controlled husbandry period; product state; whole, live, fresh, chilled, tail-only if explicitly declared, or declared product basis; size grade, carapace length, individual mass, or count per kg; shell-on or shell-off basis where material; moisture or drainage basis; geography and declared gate; holding or chilling duration; feed regime or natural-feed claim; water temperature, salinity, and exchange; health, biosecurity, permit, or certification status |

When constructing a foreground data package, the items listed in `Required qualifiers` must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package.

Mass is the primary reference basis. Count, crate, tote, cage, pond, tank, puerulus, juvenile, size-grade, carapace-length, or individual-weight records may be used only when net mass, count per kg or mean individual mass, product form, sampling method, and tare method are retained.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |

| `farmed_production_evidence` | all datasets | Record identity and production evidence | declared records | Dataset records must show controlled aquaculture production, not only wild capture followed by live holding, chilling, grading, or dispatch. |
| `product_form_mass_basis` | whole, live, fresh, chilled, tailed, drained, or packed records | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Product mass must state live whole weight, chilled whole weight, drained mass, tail mass if exceptionally declared, or another contract-declared basis. Convert only with measured yield evidence. |
| `count_to_mass_conversion` | stocking, mortality, grading, harvest, sales, and count-grade records | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Count records must include count per kg or mean individual mass, carapace length or size grade, sampling method, and product form before normalization. |
| `life_stage_identity` | broodstock, pueruli, postlarvae, juveniles, and transferred stock | Mass or count | kg, item, puerulus count, postlarval count, or juvenile count | Life-stage records must retain taxon, life stage, supplier or hatchery, batch, count, mass where measurable, development stage, health status, and transfer date. |
| `feed_mass_basis` | live feed, trash fish, mussel, formulated feed, supplements, and natural-feed claims | Mass, count, or service basis | kg, g, item, or cage-day | Feed records must state wet, dry, as-fed, live-feed, formulated-feed, or natural-feed basis. Natural-feed grow-out systems must document the absence of added feed and the grow-out service basis. |
| `water_temperature_salinity_and_volume` | hatchery, nursery, grow-out, live holding, washing, chilling, and wastewater | Temperature, salinity, mass, or volume | deg C, ppt, kg, or m3 | Preserve controlled water volume, temperature, salinity, water exchange, recirculation, make-up water, and discharge basis. Temperature control must be declared when energy use depends on chilling or heating. |
| `energy_and_fuel_inventory` | pumps, aeration, oxygenation, chilling, heating, filtration, lighting, vessels, vehicles, and delivery | Energy or fuel quantity | kWh, MJ, L, or kg | Record original electricity, fuel, oxygen, or energy carrier units before normalizing to the reference flow. |
| `chemical_and_health_treatment_basis` | disinfectants, probiotics, medicines, water-treatment chemicals, oxygen, anesthetic, and salt | Mass, volume, or active ingredient | kg, L, g active ingredient, or m3 gas | Record product quantity, active ingredient where applicable, treatment purpose, diagnosis or health plan link, legal status, and harvest eligibility consequence. |
| `packaging_and_ice_basis` | crates, boxes, bags, liners, bands, labels, insulated containers, ice, gel packs, oxygenated bags, and pallets | Mass or item count | kg or item | Packaging, ice, live packs, and containers must retain material type, item count, tare or fill mass, reuse rate, and destination before normalization. |

Key product attributes are foreground qualifiers recorded alongside the mass reference flow:

| Attribute | Common unit | Required handling |
| --- | --- | --- |
| Species or taxon | scientific and common name | required for all datasets |
| Culture system | hatchery, nursery, pond, tank, RAS, sea cage, suspended cage, ranching area, enhancement area, or declared variant | required for boundary, water, feed, mortality, and discharge interpretation |
| Biological starting condition | broodstock, hatchery seed, pueruli, postlarvae, juveniles, wild-collected seed, supplier stock, or grow-out transfer | required to distinguish farmed production from wild capture |
| Product form | live whole, fresh whole, chilled whole, shell-on, shell-off, tail-only if exceptionally declared, or declared variant | required for mass-basis interpretation |
| Size grade | count per kg, mean individual mass, carapace length, sex, maturity class, or market grade | required when count or grade records are used |

## 5. System Boundary

The default boundary covers foreground-controlled farmed rock lobster and sea crawfish production to the declared farm, hatchery, harvest, packhouse, dispatch, or delivery gate:

1. Broodstock, hatchery seed, pueruli, postlarvae, juveniles, or grow-out stock sourcing, including on-site hatchery and nursery activity when controlled by the reporting operator, or purchased and collected stock disclosure when supplied by another hatchery, fisher, collector, or farm.
2. Hatchery, nursery, grow-out, cage, pond, tank, RAS, ranching, or enhancement husbandry, including stocking, feed or natural-feed management, water intake and exchange, aeration, oxygenation, filtration, temperature control, salinity control, shelters, health management, biosecurity, mortalities, molts, and directly controlled maintenance.
3. Harvest, grading, washing, live holding, chilling, packaging, and declared gate release.
4. Delivery to the declared gate when the reference flow is delivered product rather than farm, harvest, dispatch, or packhouse gate product.

Capital goods and long-lived infrastructure are included only when the declared data package scope requires them. Purchased feed, live feed, biological stock, cages, nets, shelters, packaging, ice, oxygen, electricity, fuel, and chemicals require upstream datasets unless the same operator controls and reports their production in the foreground package.

## 7. Allocation and Co-product Handling

Avoid allocation where feasible by collecting separate batch, pond, tank, cage, hatchery, nursery, holding, and pack-out records. When the same foreground system produces multiple saleable species, size grades, seed, juveniles, market animals, shells, molts, or other products, apply the hierarchy below:

1. Use physical subdivision when records identify separate culture units, batches, species, size grades, or handling lots.
2. Use causal physical allocation when resource use is driven by measured biomass, count, cage occupancy, feed intake, water volume, holding duration, tonne-kilometres, or live-tank service.
3. Use economic allocation only when physical subdivision and causal physical allocation are not possible; disclose prices, period, market, and sensitivity.
4. Treat mortalities, culls, molts, wastewater, sludge, and used packaging as waste unless they leave the system as saleable co-products with documented market value and handling.

Wild rock lobster, Homarus lobster, Norway lobster, freshwater crayfish outside this CPC category, and processed crustacean products must be separated into their own PCR categories or modelled as co-products with explicit classification disclosure.
