Preserve explicit fish maturity-stage and source metadata without assigning reproductive status.

Description

Preserve explicit fish maturity-stage and source metadata.

Fish records distinguish morphometric length definitions, relative image scales, annulus labels, detection times and survey-effort geometry. A supplied conversion factor need not apply across species or sizes. Local labels, ratios and nominal swept areas organize observations without identifying a fish, determining age or estimating abundance.

Preserve explicit fish maturity-stage and source metadata.

When to use this tool

Use Fish Maturity Stage Source Key when you already have specimenId, suppliedStage, stagingSource and need to preserve explicit fish maturity-stage and source metadata.

How to use the tool and how it works

  1. Enter specimenId, suppliedStage, stagingSource. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read token. Use the output convention below.

Enter specimenId, suppliedStage, stagingSource using the field constraints below. Encode these values, in exactly that order, as a JSON array and return the serialized array as text in token. String values are preserved without trimming or external terminology lookup.1

  "input": {

}

Limitations and assumptions

  • The result records supplied values without assigning reproductive status. Sources and asserted relationships are not independently authenticated.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.

Alternative or Complementary methods

Inspect original specimens, images, reference definitions and survey logs when verifying observations. Use a complete species-appropriate measurement or population method for age, abundance or condition questions; local scales and effort terms preserve only their stated basis.
