Dimensions and units
- Unit
- count — source-defined reporting unit
- Reporting basis
- Organisation's reporting period
Unit meaning: Values use count under the disclosed TNFD sector-guidance method, reporting period and boundary.
Published dimensions
- Organisation activity in the fishing value chain: fishing, fish trading, fish processing, or retail
- Fishery to which reported incidences relate
- Incidence classification as illegal, unreported and unregulated fishing

Formula
Count of reported incidences of illegal, unreported and unregulated fishing across the fishery during the reporting period.Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. This is a standalone, directly reportable outcome count specified in the Fishing sector guidance as F.C3.2. It has an explicit count unit, defined subject matter, and stated fishery boundary. No shortlisted existing metric has the same IUU-incidence construct, boundary, unit, and value shape.

Evidence and status sources
Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

- Disclose the definition and classification approach used for illegal, unreported and unregulated fishing, with reference to TNFD and FAO guidelines.
- Disclose the fishery boundary covered by the count.
- Disclose the reporting period and whether duplicate reports of an underlying incident were treated as one or multiple incidences.
Record-specific limitations
- The metric counts reported incidences and therefore may not represent unreported incidents that have not been identified or reported.
- The extracted evidence does not specify whether repeated reports concerning the same underlying event must be deduplicated.
- Comparable reporting depends on consistent application of the TNFD and FAO definitions of IUU fishing.
Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.
Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
