A desktop study from the Australian Ocean Data Network investigates potential links between marine seismic surveys and commercial fish catch rates in Bass Strait and the Gippsland Basin. The analysis employs three novel generalized linear models using natural splines to examine relationships with seismic operations and environmental variables. The study, updated in April 2026, found no clear or consistent relationship between seismic surveys and subsequent fisheries catch rates.
Use Cases
- Modeling fish catch-per-unit-effort (CPUE) relationships based on seismic survey proximity and timing
- Analyzing environmental factor influences on catch rates for species like gummy shark and tiger flathead
- Investigating cumulative impacts of multiple seismic surveys on commercial fishing operations
Strengths
- Analysis includes environmental variables for four key commercial species
- Employed three distinct statistical methods to model potential impacts
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
Provenance
