Bass Strait Fisheries Catch Rates and Seismic Survey Impact Analysis

A desktop study from Geoscience Australia Data investigates potential links between marine seismic surveys 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 environmental variables. The study, last updated in 2026, found no clear or consistent statistical relationship between seismic operations and subsequent catch rates.

Use Cases

• Modeling the impact of anthropogenic noise on commercial fish populations based on catch-per-unit-effort (CPUE) data.
• Analyzing spatial and temporal relationships between industrial activity and fisheries data using generalized linear models.
• Investigating confounding effects of environmental variables and annual stock changes on catch rates for species like gummy shark and tiger flathead.

Strengths

• Analysis is based on individual commercial fishing records, suggesting detailed catch and effort data.
• Study employs three distinct statistical methods to model potential impacts, including a cumulative impacts model.
• Explicitly investigates four key commercial species: gummy shark, tiger flathead, school whiting, and silver warehou.

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.
• The study concludes the data did not permit an unequivocal outcome on seismic survey impacts.
