Bass Strait Fisheries Catch Rates and Seismic Survey Impact Analysis

A desktop study by Geoscience Australia Data investigates potential links between marine seismic surveys and commercial fish catch rates in the Bass Strait and Gippsland Basin. The analysis employs three novel generalized linear models to examine catch-per-unit-effort (CPUE) data for species like gummy shark and tiger flathead against seismic activity and environmental variables. The study, last updated on 2026-03-25, found no clear or consistent relationship between seismic operations and reduced catch rates.

Use Cases

• Modeling the relationship between anthropogenic underwater noise and commercial fish catch rates based on CPUE data.
• Analyzing the spatial and temporal influence of seismic surveys on fisheries using nearest-neighbor and cumulative impact models.
• Investigating the confounding effects of environmental variables and interannual stock changes on catch data for key species like school whiting and silver warehou.

Strengths

• Analysis includes multiple modeling approaches (three novel generalized linear models) to test for seismic impact.
• Study incorporates environmental variables and accounts for interannual ecological effects for four commercial species.
• Data is sourced from commercial fishing logbooks, providing real-world operational records.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The study concludes the data did not permit an unequivocal outcome on seismic impacts, indicating analytical challenges.
