Investigation and improvement of live Blue Swimmer Crab handling in NSW
2025
Exley, Paul | Cawthorn, Donna-Maree
This report presents pivotal findings from an in-depth investigation into optimising live handling practices for the commercial Blue Swimmer Crab (Portunus armatus) industry in New South Wales (NSW), with the overarching goal of unlocking high-value live trade opportunities. Initiated in 2019, the research was conducted by an experienced team of scientists at the Queensland Department of Primary Industries (DPI) in Coopers Plains, Brisbane. The primary objective was to develop effective handling protocols to improve the survival rates of Blue Swimmer Crabs from capture to market, thereby increasing the volume and quality of crabs available for sale. The study combined extensive literature review, laboratory trials and stakeholder engagement to provide a practical framework for fishers wishing to pursue the live Blue Swimmer Crab market, focusing on methods to reduce stress, minimise mortalities and maximise marketable yields.
