Description
Label a supplied otolith side and annulus number.
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.
Label a supplied otolith side and annulus number.
When to use this tool
Use Otolith Annulus Label when you already have specimenId, otolithSide, annulusNumber and need to label a supplied otolith side and annulus number.
How to use the tool and how it works
- Enter specimenId, otolithSide, annulusNumber. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.
Require specimenId nonempty, side left/right/unspecified and positive safe whole annulusNumber; format the record label.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| specimenId | Specimen Id | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| otolithSide | Otolith Side | Required. Text; one of "left", "right", "unspecified"; maximum UTF-16 length 8192. |
| annulusNumber | Positive recorded ring number; no age or biological ring interpretation is established. | Required. Safe integer; minimum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| label | Label | Required. Text; maximum UTF-16 length 8192. |

}Limitations and assumptions
- No annulus is identified or counted and annulus number is not converted into verified fish age.
- 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.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
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.
