Other farmed crustaceans, live, fresh or chilled

1. Scope and Applicability

This PCR guides foreground data package construction for other farmed crustaceans placed on the market as live, fresh, or chilled product when no more specific farmed crustacean PCR applies. It covers declared broodstock, larvae, post-larvae, juveniles, seed, supplier stock, hatchery and nursery activity where controlled by the reporting operator, pond, tank, cage, pen, raceway, recirculating, brackish-water, marine, freshwater, integrated, or other declared aquaculture systems, grow-out or fattening, harvest, grading, live holding, chilling, packaging, and release at the declared gate.

Covered products include aquaculture-produced crustaceans other than farmed crabs, lobsters, Norway lobsters, rock lobsters, cold-water shrimps and prawns, and other farmed shrimps and prawns when the product is live, fresh, or chilled and remains an unprocessed primary product. Excluded products are wild crustaceans, wild catch only held or chilled after capture, all products with a more specific canonical PCR, frozen, dried, salted, brined, cooked, canned, peeled, picked-meat, prepared, preserved, ornamental, seed sold as a separate input, and shell or processing residues modelled as separate products.

This is a fallback PCR. A conforming dataset must state the species or species group and why a more specific farmed crustacean PCR does not apply.

Required qualifiers	species or species group; fallback justification; broodstock, larval, post-larval, juvenile, seed, supplier, or fattening stock source; culture system; farmed proof or controlled husbandry period; product state; whole, live, fresh, chilled, soft-shell, molted, fattened, or declared product basis; size grade or count per kg; moisture, drainage, or ice-excluded basis; geography and declared gate; holding or chilling duration; feed regime; water source, salinity, and exchange; health, biosecurity, permit, certification, and unresolved Tiangong UUID substitutions

The selected Tiangong reference flow is a candidate CPC 04392 identity with a broader display name. Replace it with an exact Other farmed crustaceans, live, fresh or chilled flow when Tiangong provides one, while retaining this PCR identity.

Mass is the primary reference basis. Count, basket, box, tub, live-tank, pond, cage, or size-grade records may be used only when net mass, count per kg or mean individual mass, product form, and sampling or tare method are retained.

5. System Boundary

The default boundary covers foreground-controlled other farmed crustacean production to the declared farm, harvest, packhouse, dispatch, or delivery gate:

1. Broodstock, egg, larval, post-larval, juvenile, seed, or supplier stock sourcing, including on-site hatchery and nursery activity when controlled by the reporting operator, or purchased stock disclosure when supplied by another hatchery, collector, fisher, or farm.
2. Hatchery, nursery, grow-out, or fattening husbandry, including stocking, feed, water intake and exchange, aeration, oxygenation, filtration, salinity control, health management, biosecurity, molting management where relevant, mortalities, 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 beyond the farm, harvest, dispatch, or packhouse gate.

Capital goods and long-lived infrastructure are included only when the declared data package scope requires them. Purchased seed, larvae, juveniles, feed, packaging, ice, oxygen, electricity, fuel, chemicals, and transport services require upstream datasets unless the same operator controls and reports their production in the foreground package.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_to_reference_product	all inventory rows	normalized amount = collected amount / marketable reference product mass, with unit and product-form basis retained	collected amount, marketable product mass, product basis	kg, kWh, L, item, m3, or tonne-km per kg reference product	mass-balance-identity
stock_acceptance_balance	stocking and transfer	accepted stocked biomass = source stock mass + transferred-in mass - transfer mortalities - rejected stock - documented transfer losses	source stock, transfers, mortalities, rejects, transfer loss	accepted stocked biomass	mass-balance-identity
growth_and_survival_balance	grow-out and fattening	harvest-size biomass = stocked biomass + biological growth - mortalities - escapes - rejects, checked against harvest records	stocked biomass, feed, mortalities, escapes, harvest records	harvest-size biomass and survival disclosure	asc-farm-standard-2025
product_form_yield	harvested and packed product	marketable product mass = harvested mass - rejected mass - mortality mass - drainage, ice, tare, and handling losses according to declared product basis	harvest mass, rejected mass, product-form records, packout records	marketable live, fresh, or chilled mass	codex-cxc-52-2003
delivery_tonne_kilometres	delivered reference product	tonne-km = delivered product mass in tonnes x one-way or contract-declared route distance; allocate live-holding or temperature-control inputs by load share	delivered mass, distance, route, load factor, temperature or live-holding condition	tonne-km and delivered product inventory	mass-balance-identity

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity	reference product and biological stock	Species or species group, fallback justification, farmed status, biological starting condition, culture route, product form, and declared gate must be explicit.	reference flow metadata, stocking records, PCR selection note, harvest records, and sales or dispatch records
dq_mass_balance	stock, feed, mortality, harvest, and packout	Stocking, growth, mortality, escape, molt or shell residue, harvest, reject, and marketable product records must reconcile within declared tolerance; unexplained gaps require disclosure.	mass-balance worksheet, scale tickets, culture-unit records, packout records, and supervisor review
dq_feed_and_water_basis	feed, bait, water, and chemicals	Feed and bait basis, water salinity and exchange, treatment chemicals, and discharge route must be explicit.	invoices, feed declarations, farm logs, water-quality logs, treatment records, and discharge records
dq_temporal_coverage	all foreground rows	Data must cover the full production, grow-out, fattening, and final handling period, or disclose partial-cycle, partial-batch, or proxy coverage.	reporting calendar, batch records, harvest records, and coverage statement
dq_boundary_disclosure	all datasets	The dataset must disclose whether upstream stock, feed, water, packaging, delivery, capital goods, and infrastructure are foreground, linked upstream datasets, or excluded by scope.	dataset boundary statement, supplier records, upstream dataset links, and scope declaration

9. Validation Rules

rule_id	Rule	Severity	Failure message
val_reference_flow_uuid	Reference product flow UUID equals 429a82ee-b7ad-437e-9cfb-4c4530d82510 unless a more specific Tiangong CPC 04392 farmed crustacean product flow is documented.	error	Reference flow must use the candidate CPC 04392 crustacean identity or document a reviewed replacement.
val_fallback_scope	Dataset states why no more specific farmed crustacean PCR applies.	error	Other farmed crustaceans fallback PCR requires species and PCR-selection justification.
val_farmed_proof	Dataset has controlled aquaculture, nursery, grow-out, or fattening evidence beyond wild capture and post-capture handling.	error	Wild capture only belongs under a wild crustacean PCR, not this farmed product PCR.
val_product_state	Product state is live, fresh, or chilled and excludes frozen, dried, salted, brined, prepared, preserved, ornamental, or processed product.	error	Product state is outside the other farmed crustacean live, fresh, or chilled PCR scope.
val_mass_basis	Product mass basis is declared as live, fresh, chilled, drained, ice-excluded, whole, soft-shell, molted, or another stated basis.	error	Product mass basis is missing or ambiguous.
val_structured_sync	structured.yaml is regenerated from the bilingual Markdown after edits.	error	Structured projection is out of sync with authored PCR Markdown.
