SAFE Project: Freshwater Fish Catch Data from Danum Valley Streams 2011-2017

16,022 fish catch records were collected across streams in Danum Valley and surrounding oil palm areas from 2011 to 2017. The dataset, created by Clare L. Wilkinson of Imperial College London, includes taxonomic, biometric, and environmental data for studying vertebrate communities. It is part of the SAFE project research on composition and abundance across a land-use gradient.

Use Cases

• Analyze species abundance and distribution based on the Taxon and N (count) fields.
• Model fish growth and body condition based on Length and Weight measurements.
• Assess the impact of land-use change on biodiversity based on the Landuse field in the environmental data.
• Study fish movement and recapture rates based on the Pittagnumber and Recapture fields.
• Investigate relationships between environmental variables and fish communities based on averaged stream data.

Strengths

• 16,022 data rows provide a substantial sample size for analysis.
• 17 fields per catch record include taxonomic, biometric, and methodological details.
• The dataset includes a separate table with 23 rows of averaged environmental data by stream.
• A notes column documents data changes and corrections for transparency.

Limitations

• The dataset is described as raw and may contain errors that need correcting.
• Taxonomic identifications include noted simplifications (e.g., all Rasbora in 2013 labelled as cf. sumatrana).
• Column-level documentation is absent; field semantics must be inferred from the high-level description.
