Sea Around Us Project - Relative demersal fish abundance inferred from commercial catch da

1997-2006 relative abundance data for commercially exploited demersal fish species in northwestern Australia, mapped on a 0.5-degree spatial grid. The dataset is derived from commercial landings analysis by the Sea Around Us Project and includes catch contributions for 24 taxonomic groups. Further methodological details are available in a 2016 peer-reviewed publication by Bouchet et al.

Use Cases

• Mapping species distribution hotspots based on relative abundance data.
• Analyzing temporal trends in commercial fish catch from 1997 to 2006.
• Studying the community composition of demersal fish based on the listed taxonomic groups and their catch percentages.

Strengths

• Covers a 10-year time period from 1997 to 2006.
• Includes relative abundance data for 24 distinct taxonomic groups with specific catch percentages.
• Spatial data is mapped on a standardized 0.5-degree grid.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
