Southern Rock Lobster Catch Rates and Environmental Factors in South Australia

Parks Australia provides research on environmental influences on daily commercial catch rates of southern rock lobster (Jasus edwardsii) in the South Australian Southern Zone fishery. The analysis used multivariate weighted linear regression on daily aggregated catch rates with environmental covariates, finding wave height, bottom temperature, and moon phase among significant variables. This record was previously available via the Australian Marine Parks Science Atlas and was last updated on 2026-07-16.

Use Cases

• Modeling the relationship between catch rate and bottom temperature based on the described negative correlation.
• Analyzing the effect of wave height and period on lobster catchability as identified in the regression model.
• Investigating the influence of moon phase on daily commercial fishing success as mentioned in the study.
• Assessing spatial and temporal variance in catch rates explained by year and month factors from the analysis.

Strengths

• Analysis is based on daily aggregated commercial catch rates, providing temporal granularity.
• Model identified specific significant environmental variables including wave height, bottom temperature, and moon phase.
• Research is associated with Parks Australia and a formal scientific publication.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The described model explained 7% of variance with environmental variables, suggesting other factors are influential.
