26th Annual Symposium on Sea Turtle Biology and Conservation Island of Crete, Greece, 3-8 April 2006. Oral Presentation. The Torres Strait and northern Queensland have the largest population of green turtles in the world. This population supplies a large, internationally-based green turtle harvest, which is currently not managed. In Queensland, successful management will need the involvement of the Indigenous Torres Strait Islanders who use green turtles for cultural, social and economic purposes. This project developed community-based strategies for green turtle catch-monitoring upon which communities could base management plans. I engaged two Torres Strait Island communities in a step-wise process: (1) I obtained support from the Torres Strait Regional Authority; (2) This support enabled me to engage Traditional Owners and Community Councils in each community; and (3) I involved turtle hunters through participatory workshops/meetings. Community members helped me design a datasheet to collect data about hunting behavior needed for co-management. Hunters completed the datasheet after each hunting trip. I assessed the project's success by evaluating the proportion of hunters in the community that participated and the quality of the information they provided. We have one year of data from two communities that actively participate in hunting. Ninety-two and 25% of hunters who signed up from Hammond and Thursday Islands, respectively, handed in datasheets consistently. On Thursday Island, a larger community with a broad social structure, it was more difficult to involve community members in catch-monitoring than on Hammond Island, where there is strong community support for the project. In this paper I discuss culturally appropriate aspects of hunting behavior and catch-monitoring statistics from these two communities.

Characteristics of traditional dugong and green turtle fisheries in Torres Strait: opportunities for management. This data forms part of a PhD thesis which aimed to inform the development of management arrangements for the traditional dugong and green turtle fisheries in Torres Strait, and to provide an overall context for management at different special scales and investigating opportunities and challenges associated with co-management, particularly community-based monitoring.

This study examined the cultural acceptability of various management options for dugongs and green turtles at Hammond Island in Torres Strait. Elders and hunters participated in semi-structured interviews to examine their perceptions about various management options for dugongs and green turtles for their community.

In November-December 1991, dugongs, sea turtles and cetaceans were counted from the air at an overall sampling intensity of 5.8% over a total area of 30,560 square km in the Torres Strait region. The population estimates for dugongs an sea turtles were corrected for perception bias, and standardised for availability bias, with survey and species-specific correction factors. The estimates for cetaceans were corrected for perception bias only. Management recommendations are made. Refer to the report compiled for AFMA: Marsh H and Lawler I.

This study trialled community-based catch-monitoring strategies for dugongs and green turtles in two communities (Hammond and Thursday Islands) in the Kaiwalagal region (inner islands) of Torres Strait. Hunters completed datasheets after each hunting trip and these were collected weekly by Indigenous catch-monitors employed on the project. The catch-monitoring program was evaluated in terms of the reliability of the informaition collected and the suitability of the method to the communities. The information collected included biological information about the composition of the catch (e.g. sex ratio, size distribution, reproductive status), selectivity of the green turtle catch, catch-effort, catch-gear and the uses for which dugongs and turtles were hunted. The participating communities can use the information in future management of dugongs and green turtles in their communities.

This study assessed the relative vulnerability of Torres Strait fisheries by conducting a vulnerability assessment on 15 key fishery species. A structured semi-quantitative approach for the vulnerability assessments was applied, based on a widely-adopted framework that includes the elements of Exposure, Sensitivity and Adaptive Capacity proposed by the Intergovernmental Panel on Climate Change and United Nations Framework Convention on Climate Change. The assessments were informed by comprehensive literature reviews of Torres Strait climate (observed and projected), key fishery habitats and their vulnerability to climate change, and species reviews for 10 fishery groups that covered fishery characteristics, species life cycles and sensitivity to environmental changes. The assessments were further informed by results of interviews with Torres Strait Islanders. The results of the vulnerability assessments identified species with high, medium and low relative vulnerability to climate change. The species identified as having the highest relative vulnerability were: black teatfish, black-lipped pearl oyster, dugong, and trochus. When vulnerability was combined with the level of importance of each species to fisheries in Torres Strait (using a measure of cultural and economic value), a priority list of five species was identified for future action by management. These species were: dugong, turtle, tropical rock lobster, trochus and gold-lipped pearl oyster. This project concludes that there are a number of environmental changes that will be experienced in the Torres Strait by 2030, including habitat impacts that will have flow-on effects on a number of key fisheries. The main drivers are likely to be increases in sea surface temperature, increased severity of storms, and habitat changes particularly to coral reefs and seagrass meadows. The report also provides a range of recommendations on future actions and research that should arise from this project. These are grouped into three themes: (1) improving assessment accuracy, (2) extension of results to communities and decision-makers, and (3) research to address key knowledge gaps.
