Barents Sea Cod Diet Records from 165,000 Fish (1930-2018)

Barents Sea Atlantic cod stomach contents data collected from the 1930s to 2018. The dataset comprises quantitative diet records from more than 165,000 individual fish. Data originates from collaborative research by institutions in Norway and the United Kingdom.

Use Cases

• Modeling long-term dietary shifts in a key fish species based on the multi-decade time series.
• Analyzing predator-prey relationships and food web structure based on quantitative stomach contents.
• Investigating the impact of climate or fishing pressure on cod feeding ecology based on temporal trends.

Strengths

• Substantial sample size of over 165,000 individual fish.
• Long-term temporal coverage spanning nearly nine decades from the 1930s to 2018.
• Data represents a collaborative international effort from Norway and the UK.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
