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, last updated in May 2026, found no clear or consistent relationship between seismic surveys and fisheries catch rates.
Use Cases
- Modeling the impact of anthropogenic underwater noise on fisheries based on catch-per-unit-effort (CPUE) data.
- Analyzing spatial and temporal relationships between fishing operations and seismic survey events.
- Investigating confounding effects of environmental variables and stock dynamics on commercial catch rates for species like gummy shark and tiger flathead.
Strengths
- Analysis employs three distinct statistical methods (All surveys, Nearest neighbour, Cumulative impacts) to model potential impacts.
- Study incorporates environmental variables for four key commercial species (gummy shark, tiger flathead, school whiting, 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.
- Row count is unknown, which may limit suitability assessment.
