Bass Strait Fisheries Catches and Seismic Survey Impact Analysis

Geoscience Australia Data conducted a desktop study investigating potential links between marine seismic surveys and commercial fish catch rates in the Bass Strait and Gippsland Basin. The analysis used historical fishing logbook data and seismic survey records, employing three novel generalized linear models to test for relationships. The study, last updated in April 2026, found no clear or consistent statistical relationship between seismic operations and subsequent catch rates.

Use Cases

• Modeling the impact of anthropogenic underwater noise on commercial fish populations based on catch-per-unit-effort (CPUE) data.
• Analyzing spatial and temporal relationships between industrial activity and fishery performance using generalized linear models with natural splines.
• Investigating the influence of environmental variables on catch rates for species like gummy shark, tiger flathead, school whiting, and silver warehou.

Strengths

• Analysis employed three distinct statistical methods to test for relationships, including a novel cumulative impacts model.
• Study investigated potential confounding effects by including environmental variables for four key commercial species.
• Data originates from a government scientific organization, Geoscience Australia Data.

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.
