Careless fisherman are being blamed for an influx of dead sharks found on Simpsons Beach over the last few weeks. Broome locals were left horrified after several images were posted on a local Facebook group page showing dead sharks on the sand with a caption that read, “Another six small sharks washed up at Simpsons today”. A number of comments on the post supplied more images or anecdotes collected over the last month. Shark expert and scientist at the Australian Institute of Marine Science Mark Meekan told the Broome Advertiser there is no clear cause of the deaths of Simpsons Beach. “There are a range of potential causes,” he said. “Without an autopsy, it’s impossible to determine a definitive cause.” While scientists and locals speculate, Department of Primary Industries and Regional Development’s Director Regional Compliance North Stuart McDowall said they have had several reports of illegal fishing recently. “DPIRD compliance officers in Broome have had some reports of people line fishing and leaving some of their catch of sharks on the beach.” “We urge fishers to return any unwanted fish to the water as soon as possible with the least possible injury.” It comes only weeks after the bodies of several humpback dolphins washed ashore in Darwin. The death of the dolphins left marine biologists and environmental groups puzzled, but The Environment Centre NT’s Jason Fowler told ABC news that he believed pollution was to blame.
