Bass Strait Fisheries Catch Rates and Seismic Survey Impact Analysis

A desktop study from the Australian Ocean Data Network 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 relationships with seismic operations and environmental variables for species like gummy shark and tiger flathead. No clear or consistent relationship between seismic surveys and subsequent catch rates was identified using the available commercial logbook and seismic data.

Use Cases

• Modeling the relationship between anthropogenic underwater noise and fish catch rates based on seismic survey proximity data.
• Analyzing the influence of environmental variables on commercial catch-per-unit-effort (CPUE) for key species like gummy shark and silver warehou.
• Developing spatial-temporal impact models for cumulative seismic survey effects on fishing operations.
• Comparing statistical methods (nearest neighbor vs. cumulative impacts) for assessing confounding factors in ecological time-series data.

Strengths

• Analysis employs three novel generalized linear models with natural splines for flexible relationship estimation.
• Study investigates multiple commercial species (gummy shark, tiger flathead, school whiting, silver warehou) with environmental factors.
• Data sourced from individual commercial fishing records and seismic survey logs, providing operational-level detail.

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 available did not permit an unequivocal outcome on seismic impact, indicating analytical challenges.
