Survey studies shark depredation as bite offs affect 40 per cent of recreational fishers at Exmouth hotspots

The Mid West-Gascoyne fishing community is encouraged to share its experience with bite offs as the Department of Primary Industry and Regional Development looks at ways to reduce shark depredation. Recreational, charter and commercial fishers are reporting a higher rate of bite offs in the Gascoyne and Pilbara areas, with shark depredation occurring on 40 per cent of recreational fishing trips in the Ningaloo Marine Park and Exmouth Gulf. Shark depredation, or bite offs, occur when a shark consumes a fisher’s catch before it can be landed. A national Fisheries Research and Development Corporation project, led by Queensland’s Department of Agriculture and Fisheries, is scoping out the extent of the issue and examining potential mitigation options. DPIRD senior principal research scientist Gary Jackson said it was a significant issue for recreational, commercial and charter fishers, particularly in the Gascoyne and Pilbara. He said understanding shark behaviour, using deterrent technology and fisher education and behaviour change could contribute to resolving shark depredation. “The project is bringing together the scientific expertise and studies done by researchers across the country and internationally to explore potential new ways to address the issue,” he said. “WA’s Indigenous, commercial, recreational and charter fisheries will have the opportunity to provide feedback on their fishing experiences through an online survey in March next year. “Around the same time, DPIRD will also hold a series of regional workshops for fishing industry leaders to further explore the impacts of shark depredation on fishing, what mitigation measures have been or are currently being tested or used and new solutions for managing the issue.” To find out more, visit the DPIRD website.
