Entanglement of large whales in static fishing gear, specifically in pot fisheries, is an increasing issue worldwide. Fishing is one of the most important marine activities in Irish waters, 85% of which is happening in territorial waters. Humpback (Megaptera novaeangliae), minke (Balaenoptera acutorostrata), and fin whales (Balaenoptera physalus) are known to feed inshore during several months of the year when pot fisheries are active, bringing these whales in close proximity to these fisheries and the potential dangers they represent. This study determined the likelihood of co-occurrence of pot fisheries and large whales and identified high-risk areas and times of the year where the risk of entanglement is highest. Humpback and minke whales appeared to be more at risk off the southwest and south coast of Ireland, while higher risk areas were located off the south coast for fin whales. This research also provided insights into the current constraints and gaps in the available data. Recommendations were made on how certain types of data could be collected in the future to improve the assessment and to identify risk areas at a finer resolution. The high-risk areas identified in this study can help prioritize which areas to target.
