# Other aquatic invertebrates, live, fresh or chilled, n.e.c.

## 1. Scope and Applicability

This PCR guides foreground data package construction for other aquatic invertebrates, live, fresh, or chilled, not elsewhere classified in the more specific PCR records for fish, crustaceans, molluscs, jellyfish, sea cucumbers, sea urchins, sponges, ornamental aquatic animals, or processed aquatic invertebrate products. It covers declared harvesting, collection, or legal gathering, onboard or field sorting, live holding or chilled holding, landing, grading, washing where performed, packaging, icing or temperature control, dispatch, and release at the declared gate.

Covered products include live, fresh, or chilled aquatic invertebrates of declared species or species group that remain unprocessed primary products and are not represented by a more specific canonical PCR. Excluded products are all products with a more specific PCR in this subdomain, frozen, smoked, dried, salted, brined, prepared, preserved, cooked, canned, ornamental, extracted, manufactured, or otherwise processed products, and residues or rejected biomass modelled as separate products.

This is a fallback PCR. A conforming dataset must state why a more specific product PCR does not apply, and must preserve the species or species-group identity needed for future mapping refinement.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_mass` | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | The reference flow must be expressed as kg other aquatic invertebrates in the declared live, fresh, or chilled product form. |
| `fallback_identity_check` | all datasets | PCR selection evidence | declared records | Dataset metadata must state why a more specific PCR does not apply and must retain species or species-group identity for future mapping. |
| `product_state_identity` | all datasets | Product state and handling evidence | declared records | Product records must prove live, fresh, or chilled state and must not mix frozen, dried, salted, brined, prepared, preserved, ornamental, or processed products with the reference product. |
| `wet_drained_mass_basis` | live, fresh, chilled, washed, drained, or iced records | Mass and drainage basis | kg | Product mass must state wet whole mass, drained mass, cleaned mass, ice-excluded mass, or another declared basis. Convert only with measured drainage or yield evidence. |
| `lot_identity` | harvest, collection, aquaculture, landing, sorting, and sales records | Mass, count, or volume | kg, item, basket, tub, crate, or m3 | Lot records must retain species or species group, route, area or site, gear or collection method, vessel, collector, farm, trip, lot, date, accepted mass, rejected mass, and permit where relevant. |
| `energy_fuel_ice_water_and_holding` | harvest, collection, aquaculture holding, washing, live holding, chilled holding, and dispatch | Energy, fuel, mass, volume, temperature, or time | kWh, MJ, L, kg, m3, deg C, or h | Record fuel, electricity, water, ice, oxygen, temperature, salinity where relevant, holding time, drainage, and discharge basis before normalization. |

## 5. System Boundary

The default boundary covers foreground-controlled production or capture to the declared landing, holding, dispatch, packhouse, or delivery gate:

1. Wild harvest, gathering, collection, or declared aquaculture production when no more specific PCR applies, including gear or culture-unit operation, catch or stock handling, non-target material, bycatch, mortalities, and direct operating inputs.
2. Landing or receipt, grading, washing where performed, live holding or chilled holding, drainage, rejection, residue handling, temperature control, icing, packaging, storage, and declared gate release.
3. Delivery to the declared gate when the reference flow is delivered product beyond landing, receipt, dispatch, or packhouse gate.

Capital goods and long-lived vessels, gear, tanks, cages, holding systems, cold rooms, and infrastructure are included only when the declared data package scope requires them. Purchased stock, feed, ice, packaging, electricity, fuel, water, oxygen, and transport services require upstream datasets unless the same operator controls and reports their production in the foreground package.

| `dq_product_state` | all product rows | Dataset must not mix live, fresh, or chilled product with frozen, dried, salted, brined, prepared, preserved, ornamental, or processed product. | product descriptions, temperature logs, handling records, preservation records, and sales documents |
| `dq_mass_balance` | production, harvest, collection, receipt, sorting, drainage, and packout | Gross lot, accepted mass, rejects, mortalities, drainage, residues, and marketable product records must reconcile within declared tolerance; unexplained gaps require disclosure. | mass-balance worksheet, scale tickets, production or landing records, packout records, and supervisor review |
| `dq_temporal_coverage` | all foreground rows | Data must cover the declared harvest season, production cycle, handling lots, and dispatch period, or disclose partial-season, partial-cycle, partial-lot, or proxy coverage. | reporting calendar, trip or farm logs, handling logs, dispatch records, and coverage statement |
| `dq_boundary_disclosure` | all datasets | The dataset must disclose whether production, harvest, collection, stock, feed, water, ice, 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 `9e2938bd-46d5-4801-b52c-87c35caf9a07` unless a more specific Tiangong CPC 04590 product flow is documented. | error | Reference flow must use the other aquatic invertebrates CPC 04590 identity or document a reviewed replacement. |
| `val_fallback_scope` | Dataset states why no more specific canonical PCR applies. | error | n.e.c. fallback PCR requires a species and PCR-selection justification. |
| `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 live, fresh, or chilled n.e.c. aquatic invertebrate PCR scope. |
| `val_mass_basis` | Product mass basis is declared as wet, drained, cleaned, live, chilled, ice-excluded, or another stated basis. | error | Product mass basis is missing or ambiguous. |
| `val_required_qualifiers` | Required qualifiers are present in metadata or process notes. | warning | Reference flow qualifiers are incomplete. |
| `val_structured_sync` | `structured.yaml` is regenerated from the bilingual Markdown after edits. | error | Structured projection is out of sync with authored PCR Markdown. |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | foreground production dataset for other aquatic invertebrates, live, fresh, or chilled, n.e.c. |
| downstream_use | `secondary_dataset`; `background_dataset`; foreground reference for process or lifecyclemodel construction when route and handling records are retained |
| allowed_use | LCA modelling of declared live, fresh, or chilled n.e.c. aquatic invertebrate product at landing, receipt, dispatch, packhouse, or delivered gate |
| excluded_use | any product with a more specific canonical PCR; ornamental aquatic animals; frozen, dried, smoked, salted, brined, cooked, canned, prepared, preserved, extracted, manufactured, or processed products; residues, wastewater, bycatch, mortalities, or rejected biomass as separate products; ecosystem-service claims without a separate reviewed method |
| required_metadata | canonical PCR id; CPC 3.0 code; species or species group; n.e.c. justification; route; harvest, collection, or production area; method or culture system; landing or receipt site; live/fresh/chilled state; wet or drained mass basis; product form; holding duration and temperature; packaging state; declared gate; geography; reporting period; data owner; unresolved UUID substitutions |
| required_quality_disclosure | fallback PCR justification, product state evidence, mass balance closure, wet/drained basis, temporal coverage, allocation basis, upstream dataset links, missing foreground records, proxy rows, and reasoned-estimate ranges used only for QA screening |
| update_trigger | new Tiangong flow identities for species-specific n.e.c. invertebrates, collection gear, vessel/diver service, culture inputs, stock, feed, ice, live-holding oxygen, bycatch, mortalities, residues, packaging, refrigerant, or delivery services; reviewed quantitative evidence for fuel, yield, mortality, drainage, ice, packaging, or chilling ranges; new specific PCR that supersedes this fallback; updated Codex, FAO, or legal requirements; classification mapping change |
