Fish Otolith and Scale Collection for Age Determination

A collection of fish otoliths (ear bones) and scales, which are hard structures used for determining age. The samples were gathered from market sampling, research and commercial vessel cruises, and tagged fish recaptures. The dataset is provided by the Government Digital Service via the EU Open Data platform.

Use Cases

• Develop age prediction models based on otolith morphology and growth rings.
• Conduct comparative studies of growth patterns across different fish species mentioned in the description.
• Validate age estimation techniques using samples from known recaptures of tagged fish.
• Analyze sample provenance and collection methods (market, research cruises) for methodological research.

Strengths

• Includes multiple sample types: whole otoliths, sectioned otoliths on slides, and scales.
• Samples originate from diverse collection methods: market sampling, research cruises, commercial cruises, and tagged fish recaptures.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
