Gear modifications to avoid harm to sensitive locations
Measurement answer
What this metric measures
A structured disclosure of modified-gear adoption and associated catch, by gear type, for gear changes intended to avoid serious or irreversible harm to sensitive locations.
Specification
Metric specification
- Result format
- Structured table
- Unit
- number of vessels; percentage of vessels; kilograms of catch; percentage of catch — source-defined reporting unit

- Aggregation
- Report separately by gear type, with vessel-adoption fields and catch-volume fields retained as distinct outputs.
- Pillar
- Environmental
- Topic
- Nature-impact mitigation through fishing-gear modification
- Controlled domain
- Nature, biodiversity and land
- Entity type
- Metric
Reporting boundary
Fishing, fish trading, fish processing and retail activities using modified gear to avoid serious or irreversible harm to sensitive locations.

Value structure
Dimensions and units
- Unit
- number of vessels; percentage of vessels; kilograms of catch; percentage of catch — source-defined reporting unit
- Reporting basis
- reporting period
Unit meaning: Values use number of vessels; percentage of vessels; kilograms of catch; percentage of catch under the disclosed TNFD sector-guidance method, reporting period and boundary.
Table fields and units
- gear type
- number of vessels with gear modifications
- proportion of vessels with gear modifications (%)
- catch volume associated with modified gear (kg)
- proportion of catch associated with modified gear (%)
- sensitive-location protection context
Published dimensions
- gear type
- modified-gear adoption status
- vessel population
- catch volume
- sensitive-location protection purpose
- value-chain activity

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. Fishing additional metric F.A23.1 specifies two independently reportable output families: vessel-level adoption of modified gear and catch volume by gear type, each with a proportion. They are published together as one structured metric family while preserving the separate fields and denominators required for reciprocal mapping.
Verified sources
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.

- Describe the gear modifications included and the criteria used to determine that they avoid serious or irreversible harm.
- Disclose the denominator used for the proportion of vessels and the denominator used for the proportion of catch.
- Identify the gear-type classification and the sensitive locations to which the protection objective applies.
- Explain the organizational and value-chain coverage of vessels and catch included.
Record-specific limitations
- The extracted evidence does not define the vessel-population denominator, catch denominator, geographic extent of sensitive locations, or the technical criteria qualifying a gear modification.
- Counts, proportions and catch mass are distinct fields and must not be collapsed into a single scalar outcome.
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.
