HIMI Patagonian Toothfish Fishery Ecosystem Model Outputs and Code

Ward et al. (2025) provide supplementary data and code for a co-produced qualitative network modeling study of the Heard and McDonald Islands (HIMI) Patagonian toothfish fishery. The dataset contains outputs from 128 qualitative network models, each with 10,000 simulated quantitative instances, used to explore system responses to environmental, ecological, and fishery changes. The data and code are hosted by the Australian Ocean Data Network and were last updated in April 2026.

Use Cases

• Analyzing mean qualitative responses of ecosystem components to press perturbations based on the 8 test scenarios described.
• Investigating the influence of uncertain interaction signs on key node responses based on the analysis of 'unknown' effect signs.
• Studying relationships between system responses and perturbation strength based on the simulated model instances.
• Reproducing or extending the co-produced modeling framework for other fishery-ecosystem systems using the provided code.

Strengths

• Includes outputs from 128 distinct qualitative network model versions, capturing a range of possible interaction configurations.
• Each model version is supported by 10,000 simulated quantitative instances for analysis.
• Data is directly linked to a peer-reviewed publication (Ward et al., 2025) in the ICES Journal of Marine Science.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical needs.
• The dataset contains model outputs and code, not raw observational or survey data.
