    The Efficacy and Regulation of Shark Mitigation and Deterrent Measures Submission to: Senate Environment and Communications References Committee by Peter Stephenson BSc., ADAS 2815.3, Master Class V February 2017 As a commercial diver and fisherman with over 35 years of diverse experience I write this submission due to my ever-increasing concerns about policies governing management of and research into shark populations. I began snorkelling at the age of 7 and was a keen spear fisherman and surfer for decades although I am currently no longer active in these sports. (partly due to increasing negative shark incidents) I have a BSc. In marine science from Flinders University and have completed a number of years of marine research. Over more than four decades I have spent tens of thousands of hours observing and studying the marine environment. In recent years, particularly after my friends Peter Clarkson and Greg Pickering were attacked by white sharks, I have been researching shark attacks, shark behaviour and the possible factors influencing negative shark/ human interactions. I have also witnessed aggressive shark behaviour first hand but have luckily escaped serious injury…. so far. I currently work as an abalone diver in the South Australian Central Zone Abalone Fishery. THIS IS A MAJOR WORKPLACE SAFETY ISSUE FOR ME! THE BAITING AND HARASSMENT OF SHARKS FOR TOURISM AND SCIENTIFIC RESEARCH Despite legislation deeming the berleying, baiting, approach and harassment of white sharks illegal, governments grant exemptions and licences to tourism operators and scientists to conduct these activities. Despite years of research and observation, the level of conditioning of sharks by repeated berleying and baiting is still poorly understood and documented.

  • Our World-Underwater Scholarship Society ®
    our world-underwater scholarship society ® 47th Annual Awards Program – June 3 - 5, 2021 Welcome to the 47th anniversary celebration of the Our World-Underwater Scholarship Society®. It has always been a great pleasure for me as president of the Society to bring the “family” together each year in New York City, so of course it is with great disappointment that for the second year we are unable to do so. A year ago, as the pandemic was beginning to spread throughout the world, the board of directors made the difficult decision to put all scholarship and internship activities on hold. 2020 was the first time in the Society’s history that we did not put Scholars or Interns in the field. But there is good news – the Society has new energy and is working with our hosts and sponsors to safely get our incoming 2021 Scholars and Interns started on their journeys. We bring three new Rolex Scholars and five new interns into our family for a total of 103 Rolex Scholars and 107 interns since the inception of the Society, and all of this has been accomplished by our all-volunteer organization. Forty-seven years of volunteers have been selfless in their efforts serving as directors, officers, committee members, coordinators, and technical advisors all motivated to support the Society’s mission “to promote educational activities associated with the underwater world.” None of this would have been possible without the incredible support by the Society’s many organizational partners and corporate sponsors throughout the years. The one constant in the Society’s evolution has been Rolex which continues to support the Society as part of its Perpetual Planet Initiative.

    This week’s serving won’t mean much to our readers who live inland from the ocean, for instance, Zimbabwe (where several hundred of our e-friends live) is entirely land-locked – far from the ocean. We can read about something, maybe even watch a TV report on it, but it’s just not the same as being there! But for anyone who has lived near the ocean and had an encounter of the kind this Friday Food 'n' Therapy focuses on….. there is a primal fear that rises up that words can’t describe. In coastal Australia there is an expression that says it all…. GREAT WHITE….. This is not referring to an overweight murungu (white man)! But to the white pointer shark – the most efficient killing machine known on earth. Yes, the film JAWS exaggerated their size (they have been caught “only” up to 7 metres long), but the reality of what the more common 5m long specimens can do is legendary in our part of the world. Most Saturday mornings, I jog (while Elizabeth walks with our dog) with our running club alongside Georges River, some 30km from the ocean. There are signs nearby warning bathers about sharks. In 1936 a 5m shark lost its way up the river, and hungry, it killed and ate two people in two weeks. About five years ago, I swam across the same river nearby (where it’s only about 300m across); on the other side a man warned me that a dog was taken by a shark only the week before….

Information on 26 Neophoca cinerea breeding colonies in South Australia The Australian sea lion Neophoca cinerea is restricted to South Australia and Western Australia. This supplementary material provides information on 26 breeding colonies in South Australia that were visited during this study between 2004 and 2008, with details on pup population estimates from which best estimates are summarized in Table 1 of the main paper. It also summarises data on pup counts available before 2004. Mark-recapture estimates are presented with their 95% confidence limits (CL). Detailed counts of all animals in these colonies have been presented in consultancy reports. Data for the other 13 breeding colonies and 9 haulout sites with occasional pupping (which were not visited in this study) were taken from published literature. In addition, 24 haulout sites of the Australian sea lion visited during the study are listed in Table S1 of this supplementary material, together with their geographical positions and counts of sea lions seen on the dates visited.
