Sharks International, Cairns, Australia 2010 v ACKNOWLEDGEMENTS This PhD is the result of a 22 year dream. I have always been drawn to the ocean, my ambitions to pursue marine research reaches back to my earliest memories. This thesis is for all of you who stood by me while I chased my dreams. During my studies there were many deviations; there was the sky diving, chasing anthrax in Africa, quest to be a cage fighter, far flung teaching assignments of questionable morality, and a category I will label adventures with Gutteridge. I would like to thank my supervisors for their patience as I wondered off the path, guidance and persistence as I found my way through the journey which is a PhD. Colin Simpfendorfer; I will be forever in debited to you for showing me the realities of fisheries management. This project would not have been possible without your open door policy, informal manuscript altering chats and insightful guidance as I negotiated the world of sharks research and egos. Andrew Tobin, I have had few male role models, you stand tall among them. I hope one day I too can wear my heart on my sleeve, balance my family with work and always have employment where footwear is optional. Michelle, this was not easy, there were many times when it was definitely not comfortable. However, what I have learned through our time together extends well beyond the bounds of the thesis. I am a better scientist, and holistically a better person from the experience. Your capacity for critical thinking, attention to detail and ability to see through the B.S. have been invaluable tools through the production of this thesis and I thank you for persisting with me through all the trials. My research project would not have been possible without the support of everybody at the Centre for Sustainable Tropical Fisheries and Aquaculture. My brother is arms Andrew Chin, you talked me off the ledge so many times I have lost count. Always remember “Rule 32: Enjoy the little things”. Al Harry, thank you for your tireless patience
