Bass Strait Fisheries Catches and Seismic Survey Impact Analysis

A desktop study by the Australian Ocean Data Network investigates potential statistical relationships between marine seismic operations and commercial fish catch rates in the Bass Strait and Gippsland Basin. The analysis uses historical fishing logbook data and seismic survey records, employing three novel generalized linear models to account for spatial, temporal, and environmental factors. The study, last updated in June 2026, found no clear or consistent relationship between seismic surveys and subsequent fisheries catch rates.

Use Cases

• Modeling the impact of seismic surveys on catch-per-unit-effort (CPUE) based on the described spatial and temporal proximity methods.
• Analyzing relationships between environmental variables and historical catch rates for species like gummy shark and tiger flathead.
• Assessing cumulative anthropogenic impacts on fisheries using the described 'Cumulative impacts' modeling method.
• Comparing fisheries data before and after seismic events using the described mean comparison analyses.

Strengths

• Analysis is based on individual fishing records, which likely provides detailed catch and effort data.
• Study employs three distinct statistical methods to investigate potential relationships from different angles.
• Environmental factors were included in analyses for four key commercial species.

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.
• Row count is unknown, which may limit suitability assessment.
