Oct.08, 2013 at 7:03 pm, under Shark News Stories

Perth Now reports that a “catch and kill” order has been issued by the Department of Fisheries after an abalone diver was bitten by “what’s believed to be a great white shark” today.

Greg Pickering suffered serious injuries to his head, arms, chest and face and is currently being treated at Royal Perth Hospital. According to a WAtoday report, Pickering was in stable condition. Pickering survived a shark bite to the leg from a bronze whaler (Carcharhinus brachyurus), also known as a copper shark, in 2004.

Hooks and lines have been set near the site of the attack, according to Fisheries Director General Stuart Smith, who went on to say he would likley give the order to destroy a “sizable” white shark (Carcharodon carcharias) if one is caught in the area. According to the 7News Perth report above, the size of shark is unknown, but white sharks are known to frequent the area where the attack occurred.

It was unclear from reports and Fisheries statements if/how the shark responsible for the the attack would be identified.

Indonesia’s ‘walking’ bamboo shark highlights conservation efforts

Sep.03, 2013 at 10:25 am, under Shark Conservation, Shark Videos

Dr. Mark Erdmann recently posted an article discussing how the recent discovery of a “walking” bamboo shark highlights a shift in Indonesia’s shark conservation attitude. According to Erdmann, Indonesia has gone from leading the world in the export of dried shark fins for almost three decades to creating regulations to protect elasmobranchs (including shark and ray sanctuaries in Raja Ampat and West Manggarai). Erdmann cites an increased awareness of the importance of sharks due to both their role in the ecosystem and potential economic value through eco-tourism.

Scientific discoveries such as the newly discovered ‘walking’ shark (Hemiscyllium halmahera) present an opportunity to the government and local business to promote tourism to Indonesia. The species of bamboo shark uses its fins to ‘walk’ along the ocean floor and could potentially serve as symbol for marine conservation efforts in the region.

Réunion Island plans to kill a total of 90 bull and tiger sharks

Aug.08, 2013 at 11:46 am, under Shark News Stories

According to a report from Surfer magazine government officials of France’s Réunion Island have released a plan in response to a spate of fatal shark attacks. There have been five fatal attacks in Réunion’s waters since 2011, including two fatalities in the past 4 months this year.

The government plan includes a call for 90 sharks to be killed, between now and October 1, as part of a “scientific ciguatera program to assess the marketing objectives of sharks in Réunion Island.” Ciguatera is foodborne illness associated with eating fish at the top of their food chain. GrindTV reports that the plan specifically will target 45 tiger sharks (Galeocerdo cuvier) and 45 bull sharks (Carcharhinus leucas). The article also points out that the ciguatera program could be perceived as an attempt to mask the shark cull under the guise of science.
