Ecological Risk Assessments (ERAs) have been employed in many Commonwealth fisheries for over 20 years across fishing methods including trawling, Danish seine, dredging, hand collection, longlining and gillnetting. The ERA approach is hierarchical (Levels 1, 2) and evaluates risk to bycatch, byproduct as well as EPBC Act-listed protected invertebrate and vertebrate species and provides an assessment of all species that interact with each fishery which in some cases totals over 500 species. One of the main objectives of this data-limited approach is to assist fisheries management by evaluating low, medium and potential high-risk species so that future mitigation measures can be developed to protect species, reduce ecological impacts and support sustainable fisheries. ERA outcomes are fully automated to enable accessibility and reproducibility to accommodate management needs. This paper discusses the current automated, modular CSIRO approach for ERAs and provides examples of outcomes for various Australian fisheries during the past two decades.
