Sand Flathead account for well over half of the total catch (by numbers) taken by marine recreational fishers in Tasmania and represent the mainstay of Tasmania's recreational fishery. Furthermore, since the recreational catch of sand flathead is more than 20 times the commercial catch, trends in commercial catch and catch rates are of little value in inferring changes in stock status. This has meant that fishery independent or novel assessment methods are required. To date, IMAS has implemented a research program focused on sand flathead in the south-east of the state that provides a spatially restricted, perspective and semi-quantitative evaluation of stock condition. Given the significance of the species and a status of 'depleting' in the latest stock assessment report, there is a need to implement a more comprehensive stock monitoring approach throughout the state that can support the development of a spatially explicit quantitative stock assessment model. There is also a need to determine the appropriate spatial resolution to apply to the stock assessment model. As such, there is a need to understand the extent of adult movement and ontogenetic connectivity of regional sub-populations of sand flathead throughout Tasmania. In addition, by collation of biological data sets from historical studies and surveys conducted around Tasmania the extent and direction of potential changes in population size structures, and life history characteristics will be investigated. Where possible collated biological data will be used to assess spatial and temporal changes in life history characteristics to assess the implications of selective excessive fishing pressure and/or past and future climate change effects for this species.

To secure the future of Australian aquaculture, building and maintaining a sufficient level of support and trust from interested and affected communities is vital. Worldwide, there have been several examples of where aquaculture operations have been threatened because of a lack of societal acceptability. In Australia, a recent example of this has been the environmental non-governmental organisations (eNGOs) campaigns against proposed fish farm operations in Okehampton Bay on Tasmania’s east coast (Murphy-Gregory, 2017). In the Tasmanian context, attitudes toward the commercial exploitation/use of natural resources involve multi-dimensional, often conflicting, values often with a spatial dimension (see Evans, Kirkpatrick & Bridle 2018).

FRDC Project 2017-158 ‘Determinates of socially-supported wild-catch and aquaculture fisheries in Australia’ has revealed that several factors contribute towards achieving community acceptance: the perception that a company offers benefits; that it contributes to the well-being of the region and respects the local way of life; that it listens, responds and exhibits reciprocity; and that relations are based on an enduring regard for each other’s interests. These factors are often based on understanding and contributing towards achieving a certain state or condition of that which is valued by local and regional communities (e.g. a certain level of local employment, or of threatened habitat protection). Indeed, a lack of social acceptance for the aquaculture industry has often resulted in part from their practices being seen to, or in some cases actually, compromising the condition or state of what communities ‘value’ (feel is very important).

This project has been designed to examine the mix of community interests and values, and to identify how the aquaculture industry and regional communities can participate in processes of negotiation, to contribute towards the achievement of desired conditions or states of community values, using NW Tasmania as a case study.
