Rock lobster and other sea crawfish, frozen, dried, salted or in brine

1. Scope and Applicability

This PCR supports foreground data packages for rock lobster and other sea crawfish preserved and marketed as frozen, dried, dry-salted, or in brine. The producer shall declare exactly one preservation route for each reported result. Route-specific inputs, yields, wastes, storage conditions, and results shall remain separate; a multi-route average is allowed only when each route result and the aggregation basis are also disclosed.

The foreground boundary begins with received live, fresh, chilled, or otherwise declared source crustaceans at the processing gate and ends with 1 kg net preserved product at the producer gate after packaging and, for the frozen route, frozen storage to the declared dispatch point. Harvesting or aquaculture, feed, vessel operations, and inbound transport are represented by upstream datasets. Distribution after the producer gate, retail, consumer preparation, and end-of-life are excluded unless separately added by the study.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivide_routes	frozen, dried, dry-salted, and brined production	Subdivide route-specific processes, utilities, yields, and wastes before allocation. Report each route result separately and do not use an unconditional multi-route average.	eu-pef-2021-2279
allocation_shared_operations	shared preparation, packaging, and site utilities	Use direct measurement first; otherwise use a documented physical causal driver such as processed mass, metered operating time, or capacity-time. If no physical relationship can be justified, use a documented economic allocation with contemporaneous prices and a sensitivity result.	eu-pef-2021-2279
allocation_residues_and_coproducts	shell, viscera, rejects, recovered product, and other outputs	Classify each output as product, co-product, or waste using its actual destination. Avoid allocation by process subdivision; when unavoidable, apply the same physical-then-economic hierarchy and disclose any credits or substituted products separately.	eu-pef-2021-2279

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_net_reference_mass	packaged preserved output	net target product mass = gross filled unit mass - primary packaging mass - free glaze mass - free packing brine after the declared drainage procedure	gross mass; packaging mass; glaze mass; drained free-brine mass; shell-in-presentation declaration	kg net target product	codex-cxc-52-2003
calc_process_mass_balance	preparation, preservation, and packaging	reconcile measured inputs with product outputs, separately measured residues, wastewater or spent brine, retained water or salt, and documented stock change; investigate unexplained imbalance	protocol mass records by process and lot	route-specific yield and reconciliation result	eu-pef-2021-2279
calc_normalized_utilities	all utilities	normalized utility = route-attributed utility quantity / conforming net reference-product output	meter or invoice quantity; allocation driver; net output	kWh or MJ per kg net reference product	eu-pef-2021-2279
calc_refrigerant_loss	frozen storage	refrigerant loss by substance = opening inventory + additions - closing inventory - documented recovery; allocate only to included equipment and storage period	substance-specific inventory and service records; stored output	kg refrigerant emitted per kg net frozen product	fao-fisheries-technical-paper-340

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity_and_route	every dataset	Declare species or commercial group, presentation, shell/cooking status, exactly one preservation route, net-mass method, packaging, and gate condition.	product specification; batch record; label; route code
dq_temporal_and_site_coverage	foreground records	Use a representative period covering all included lots, routes, shifts, and seasonal conditions; disclose exclusions, shutdowns, and shared-service allocation.	production calendar; lot list; meter coverage; exclusion log
dq_measurement_and_reconciliation	mass, water, energy, salt, packaging, waste, and refrigerant	Retain calibration or invoice evidence, reconcile process balances, and investigate missing records, outliers, and unexplained losses before aggregation.	calibration certificates; invoices; balance worksheets; corrective-action records
dq_upstream_and_proxy_quality	upstream datasets	Assess technological, geographical, temporal, and precision/completeness suitability; disclose proxy choices and material mismatches.	dataset metadata and documented data-quality rating consistent with eu-pef-2021-2279
dq_reasoned_estimates	all provisional ranges	Do not use these QA ranges as measured foreground values. Replace each with collected or accepted source-backed evidence, or document reviewer acceptance and uncertainty before activation.	review record; replacement source or approved uncertainty note

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference_flow	reference flow and packaged output	Verify one reference flow equals exactly 1 kg net target product using the declared drainage, glaze, packaging, and shell basis and the specified Mass property and unit group UUIDs.	codex-cxc-52-2003
validate_single_route	process map and inventory	Verify exactly one of frozen, dried, dry_salted, or brined is declared for each result; frozen storage shall appear only for frozen, while salt and brine inputs shall appear only when used by the declared route.	codex-cxc-52-2003; unsd-cpc-3-0-2025
validate_mass_and_utility_completeness	foreground inventory	Verify process mass reconciliation and coverage of material water or ice, electricity, thermal energy, salt, packaging, residues, wastewater or spent brine, and refrigerant flows applicable to the route; require a documented zero or exclusion for any applicable missing flow.	eu-pef-2021-2279
validate_food_safety_traceability	lot and route records	Verify traceable lots and applicable time-temperature, hygiene, drying, salting/brining, and release-control records are retained; failure is a data-quality finding and this PCR does not certify legal compliance.	codex-cxc-52-2003
validate_provisional_ranges	reasoned-estimate QA guardrails	Flag values outside a provisional range for investigation, but never replace foreground records with the range; all provisional ranges remain review items before activation.
validate_uuid_completeness	non-reference inventory flows	Before activation, resolve and review Tiangong UUIDs for material non-reference flows or document an approved semantic fallback; the reference flow UUID is mandatory.
