Freshwater fish, frozen

1. Scope and Applicability

This PCR covers foreground processing of freshwater fish from receipt at a freezing facility through preparation, freezing, optional glazing, packaging, and frozen storage to the declared facility gate. Covered product forms are whole, drawn, gutted, headed, scaled, or otherwise dressed freshwater fish that remain fish rather than fillets or separated fish meat. The data producer shall declare species, wild or farmed origin, received form and temperature state, dressing state, glaze status and mass basis, packaging format, freezing technology, storage temperature and duration, geography, and reporting period.

The PCR excludes live, fresh, or chilled fish; frozen fish fillets; separated fish meat whether minced or not; fish livers and roes; breaded, cooked, smoked, dried, salted, fermented, canned, or otherwise prepared products; marine fish; crustaceans, molluscs, and other aquatic invertebrates. Fishing, aquaculture, landing, and production of received fish are represented by upstream datasets. Distribution after the declared facility gate, retail, preparation, consumption, and end-of-life are outside this foreground boundary unless separately added.

5. System Boundary

The foreground system starts when received freshwater fish crosses the freezing facility boundary. It includes acceptance control, unloading, washing and dressing when performed, freezing, optional glazing, packaging, frozen storage, internal handling, sanitation attributable to included operations, wastewater and residue transfers, refrigerant loss, and treatment activities operated inside the facility. Capital goods are excluded from the default foreground inventory unless material to the declared study or required by an applicable downstream method.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_avoid	shared processes and multi-output operations	Subdivide metered operations or use direct causal assignment before applying allocation. Preserve separate records where a process or utility can be measured independently.	eu-pef-2021-2279
allocation_physical	fish products, saleable by-products, residues, utilities, and shared storage	When allocation cannot be avoided, use a documented physical relationship that reflects the causal use of resources or generation of outputs; mass is not automatic when another physical driver is more causal.	eu-pef-2021-2279
allocation_other_relation	multi-output operation lacking a defensible physical relation	Use another documented relationship, including economic allocation only where physical causality is not defensible; record values, currency, price period, geography, and sensitivity.	eu-pef-2021-2279
allocation_waste_reclassification	residues and rejected fish	Treat a flow as a co-product only when it has a documented product function and destination; otherwise model the declared waste treatment without assigning an invented credit.	eu-pef-2021-2279
