Salmonidae, frozen

1. Scope and Applicability

This PCR covers foreground production of frozen fish of the family Salmonidae supplied as whole, headed, gutted, dressed, or comparable non-fillet presentations. Products may be glazed or unglazed and bulk- or retail-packed. The product is preserved by freezing and remains frozen through the declared dispatch gate.

The foreground route begins with reception of identified salmonid fish at the processing facility and includes applicable receiving, grading, washing, bleeding or evisceration, freezing, glazing, packaging, frozen storage, and dispatch operations. Aquaculture, fishing, hatchery, feed production, vessel operation, and transport to the declared facility gate are represented by linked upstream datasets rather than silently absorbed into the foreground.

This PCR excludes fresh or chilled fish; frozen fillets; separated or minced fish meat; smoked, dried, salted, cooked, canned, or otherwise prepared fish; non-salmonid species; and products whose principal preservation route is not freezing. A repacking-only operation using already-frozen salmonid input must declare that starting condition and must not claim an unperformed freezing process.

Food-safety and quality controls are recorded because they define the valid production state and the records needed to interpret the inventory. Conformity with this PCR is not a food-safety certification.

Required qualifiers	salmonid species or declared taxon; wild or farmed origin; whole, headed, gutted, dressed, or other non-fillet presentation; skin and bone status; glaze status and glaze fraction; packaging format; freezing location and technology; received product state; dispatch temperature condition; frozen-storage duration; geography and production period

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

The reference amount is net target-product mass. Packaging, removable glaze, free water, pallets, and transport containers are not part of the 1 kg reference amount. Bones, skin, head, and viscera are included only when retained in the declared sale presentation.

calc_01_net_mass	Reference product	net target-product mass = gross packaged mass - packaging mass - removable glaze mass - free water and non-product tare	gross_mass, package_mass, glaze_mass_or_fraction, tare	kg net frozen target product	codex-cxc-52-2003; codex-cxs-190-1995
calc_02_yield	Preparation and full foreground	net yield = net frozen target-product mass / accepted salmonid input mass; report co-product and waste fractions separately	accepted_mass, net_product_mass, co-product_mass, waste_mass	yield ratio and reconciled mass fractions
calc_03_energy	Each foreground process	process energy per process output = reconciled carrier-specific process energy / measured process output	meter readings, excluded use, allocation driver, output mass	kWh or MJ per kg process output
calc_04_storage_service	Frozen storage	storage service = occupied product mass multiplied by actual storage duration; allocate storage electricity and shared refrigerant loss by the documented service driver	kg in storage, entry and exit time, storage electricity, shared system loss	kg-day, kWh/kg-day, and kg refrigerant per kg-day
calc_05_refrigerant_loss	Refrigeration systems	refrigerant loss = opening charge + additions - recovery - closing charge, reconciled by chemical and excluding transfers documented to another system	opening_charge, additions, recovery, closing_charge	kg loss by refrigerant chemical
calc_06_allocation	Multi-output operations	apply subdivision first; otherwise apply the selected documented causal physical relationship; use economic fallback only with price-period and sensitivity disclosure	process inputs and emissions, co-product quantities, physical driver or representative prices	allocated inventory by output	eu-pef-2021-2279

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_01_identity_traceability	All product lots	Preserve species or taxon, origin route, supplier, presentation, received state, lot links, and mass transfers from receipt through dispatch.	Receiving records, production genealogy, labels, and dispatch documents; unsd-cpc-v3-2025; codex-cxc-52-2003
dq_02_temporal_representativeness	Foreground inventory	Cover a representative production period including material seasonality and cold-storage duration, normally 12 months; justify a shorter campaign and disclose excluded shutdowns or abnormal operation.	Meter coverage, production calendar, storage records, and representativeness statement
dq_03_measurement	Mass, water, energy, temperature, and refrigerant data	Use calibrated instruments where measurement is required; retain units, conversion factors, missing-data treatment, and meter-to-process reconciliation.	Calibration certificates, raw readings, invoices, and reconciliation worksheets
dq_04_completeness	Foreground boundary	Account for all included processes, utilities, packaging, glaze, co-products, wastes, wastewater, refrigerant losses, rework, and product loss; quantify and justify exclusions.	Process map, mass and energy balances, waste manifests, and gap register; eu-pef-2021-2279
dq_05_cold_chain_quality	Freezing and storage	Retain lot-specific freezing completion evidence, storage duration, temperature monitoring, excursions, corrective action, and packaging or glaze integrity checks.	Time-temperature records, alarms, inspections, and corrective-action records; codex-cxc-52-2003
dq_06_safety_context	Food-contact operations	Retain hygiene, water suitability, hazard-control, contamination prevention, and packaging conformity records needed to demonstrate that the modelled output was marketable product.	Facility prerequisite and hazard-control records; codex-cxc-52-2003; conditionally codex-cxs-190-1995
dq_07_provisional_ranges	Every reasoned-estimate range	Treat the range as a replaceable screening guardrail, flag values outside it for investigation, and replace it with foreground or reviewed source-backed evidence before reviewed or published use where material.	Manifest review metadata, reviewer decision, and replacement evidence

9. Validation Rules

rule_id	Applies to	Rule	source_ids
val_01_reference_identity	Reference flow	Require exactly 1 kg net target-product mass, product flow UUID a9f77412-4b2a-4d64-b893-7356d0173ed0, Mass property UUID 93a60a56-a3c8-11da-a746-0800200b9a66, unit-group UUID 93a60a57-a4c8-11da-a746-0800200c9a66, and unit kg.	unsd-cpc-v3-2025
val_02_qualifiers	Reference product metadata	Fail completeness when species or taxon, origin route, presentation, received state, glaze status, packaging, freezing route, storage duration, dispatch condition, geography, or production period is absent.	unsd-cpc-v3-2025; codex-cxc-52-2003
val_03_net_mass	Product amount	Check that packaging, removable glaze, free water, pallets, and transport containers are excluded from the reference amount and that gross-to-net calculation inputs reconcile.	codex-cxc-52-2003; codex-cxs-190-1995
val_04_process_coverage	Foreground boundary	Require reception, applicable preparation, actual freezing or explicit already-frozen starting condition, applicable glazing and packaging, frozen storage, and dispatch; require reasons for every omitted conditional process.	codex-cxc-52-2003; eu-pef-2021-2279
val_05_cold_chain	Frozen product validity	Require freezing-completion and storage time-temperature records, excursion and corrective-action disclosure, and a frozen condition at the declared dispatch gate.	codex-cxc-52-2003
val_06_balances	Mass, water, and energy data	Require lot mass reconciliation, water and ice separation, carrier-specific energy totals, allocation of shared utilities, and quantified unexplained balance gaps.	eu-pef-2021-2279
val_07_allocation	Co-products and shared services	Require the allocation hierarchy, selected driver, co-product or waste classification, price period when economic fallback is used, and sensitivity disclosure for material allocation choices.	eu-pef-2021-2279
val_08_refrigerants	Refrigeration	Require refrigerant chemical identity and reconciled service records; reject treating the full equipment charge as an emission and flag unassigned confirmed losses.
val_09_reasoned_estimates	Provisional ranges	Identify every reasoned_estimate, require justification and replacement status, and flag values outside a QA range for investigation rather than automatic substitution.
val_10_food_safety_context	Product validity	Require the applicable hygiene, hazard-control, water-suitability, glaze or net-content, packaging-integrity, and lot-traceability evidence; report that PCR validation is not food-safety certification.	codex-cxc-52-2003; codex-cxs-190-1995
