Use of wild resources efficiency — fishmeal
Measurement answer
What this metric measures
Reports fishmeal-related dependency on wild fish resources for each farmed fish species through either the Fishmeal Forage Fish Dependency Ratio or an absolute dependency on wild catch.

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. This is a standalone TNFD Aquaculture outcome metric. The source evidence describes two permitted output forms and does not supply sufficient method detail to normalize them into one quantitative identity, so both are preserved as explicit structured alternatives.

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.

Method disclosures required
Source-edition basis: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).
- Identify each farmed fish species covered.
- State whether the reported result is the Fishmeal Forage Fish Dependency Ratio or absolute dependency on wild catch.
- Disclose the unit used for any absolute dependency quantity.
- Describe the feed boundary, wild-catch dependency treatment, calculation method, and data sources.
Record-specific limitations
- The extracted specification permits either a Fishmeal Forage Fish Dependency Ratio or absolute dependency on wild catch; the selected indicator basis must be identified for comparability.
- The extracted evidence does not specify the unit, formula, data source, or consolidation boundary for an absolute dependency quantity.
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.
