North Sea Cod Growth and Otolith Data for Climate Impact Studies

Otolith age, length, and growth increment measurements for North Sea cod (*Gadus morhua*), likely collected over a long time series. The dataset includes high-resolution photographs and is provided by the Government Digital Service via the EU Open Data platform. It is intended for investigating direct impacts of temperature changes on fish stocks.

Use Cases

• Modeling climate-driven changes in fish growth rates based on otolith increment data.
• Assessing the relationship between temperature and spawning success or recruitment mentioned in the description.
• Analyzing long-term phenological shifts in cod populations as an indicator of climate change.
• Training image analysis models to extract biological metrics from high-resolution otolith photographs.

Strengths

• Includes high-resolution photographs alongside tabular measurements.
• Focuses on a commercially and ecologically significant species, North Sea cod (*Gadus morhua*).
• Designed for analyzing long time series data to detect climate impacts.

Limitations

• Row count, file formats, and specific temporal coverage are unknown.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
