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.

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.

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
