SLAs often include many elements, from the definition of services to the termination of the contract. [2] In order to ensure rigorous compliance with ALS, these agreements are often designed with specific lines of demarcation and the parties concerned must meet regularly to create an open communication forum. Rewards and penalties that apply to the supplier are often set. Most ALS also leave room for regular (annual) revisions to make changes. [3] The existence of deciduous teeth for dugongs has been investigated. In total, 41% of men and 54% of females had hardwood teeth. However, 100% of dugongs over 2.31 m did not have hard teeth, while 77% of dugongs less than 2.31 m in length had hardwood teeth. This questionnaire was largely based on the Rapid Bycatch evaluation developed by Jeff Moore and colleagues (2010), which followed previous discussions between Andy Read, Catherine Muir and Jeremy Kiszka. We thank Lisa Campbell and Grant Murray for their evaluation of the questionnaire by social scientists and Jeff Moore and Rebecca Lewison for their informative advice in designing the questionnaire. The UNP-CMS Dugong MoU secretariat provided seed funding for the development of this questionnaire and for subsequent field trials. We thank the Abu Dhabi Environment Agency for its continued support of the MoU secretariat and financial contributions to UNEP-CMS.

We also thank Chris Cleguer for providing access to the dugong distribution model and relative density based on information collected from aerial photographs in New Caledonia. We are grateful to each and every one of our respective institutions for having been able to invest time in this company and the countless project coordinators and interviewers who implemented the field questionnaire program. This manuscript is dedicated to the memory of Dr. Kanjana Adulyanukosol, whose immense contribution to the biology of dugong and the protection of biodiversity will always be remembered in several developing countries. The authors are grateful for the research funding by the Centre of Excellence of Veterinary Bioscience, Faculty of Veterinary Medicine, Chiang Mai University, Chiang Mai, Thailand and the Center of Excellence in Osteology Research and Training Center, Faculty of Medicine, Chiang Mai University, Chiang Mai, Thailand. A special thank you goes to the Phuket Marine Biological Center for the friendly supply of dugong bone samples used for education and research. Pocock, R.I. A few notes on the dugong. Ann.C`s good.

The two most common types of fishing gear used by respondents were gillnets (27%) and hooks and line (25%; Table 2). The largest proportion of dugongs was caught in gillnets (27%), with the lowest share coming from trawling (1%).
