Anecdotal reports from Australia’s Eastern Tuna and Billfish Fishery suggest that fishing for broadbill swordfish (Xiphias gladius; hereafter ‘swordfish’) in anomalously warm waters is linked with a condition known as myoliquefaction (colloquially, “jellymeat”). Myoliquefaction affects the marketability of fish by turning the meat into a soft, mushy texture post-mortem, reducing profits and increasing wastage, and has been associated in other fish species with parasites of the genus Kudoa. A thermally sensitive mechanism underpinning myoliquefaction may increase the likelihood of the condition’s incidence as oceans warm due to marine climate change. However, the links between physical seascape conditions and the mechanisms underpinning myoliquefaction are unknown, increasing uncertainty in understanding the frequency and intensity of future events, and the associated consequences for industry.
