Over the past three decades the Tasmanian Eastern Zone Abalone Fishery has experienced several fluctuations in catch and catch rates of Blacklip Abalone as well as environmental perturbations, which may be affecting productivity. The capacity to measure inter-annual variation in Blacklip Abalone...
This project has led to the development of three journal articles examining how the use of economic analyses and stock enhancement can lead to improved economic outcomes in Australian wild-capture commercial fisheries. The Seafood Cooperative Research Centre (Seafood CRC) Future Harvest (FH)...
The management of abalone stocks is difficult for many reasons including their high value and the exceptional levels of spatial structuring found in their stocks. In Tasmania, for example, suggestions to change such things as a legal minimum length or introduce a formal harvest strategy to replace...
At low-levels of exploitation, commercial harvesting of long-spined sea urchins was found to prevent increase in urchin density. Adjacent unfished locations experienced an increase in both urchin density and grazed area over the 2014 – 2016 study period. Research sampling of populations...
It is desirable for any primary producer to understand the health and welfare of their stock. This will ultimately enable optimal production and return on investment. The challenge in any aquaculture system is ‘observing’ the physiological and behavioural responses associated with environment,...
Management Strategy Evaluation (MSE) methods are used to examine the performance of prospective Harvest Control Rules for calculating the Total Allowable Catch (TAC) for the Western Zone (WZ) Abalone Fishery. Of particular importance is recovery of the stock following the combined effects of...
Climate change science can be complex, difficult to understand, confusing and contentious. To maximise opportunities for adaptation, increased knowledge and understanding of climate change is essential. The project ‘Climate Change Adaptation: Building Community and Industry Knowledge,’...

Marine Discovery Centres Australia (MDCA) is a network of marine education facilities across Australia that provides high quality education and engagement experiences for the wider community. These learning experiences promote sustainable behaviour in, and stewardship of, our fisheries and...
Fishing activity was captured across 53,852 one Hectare hex grid cells across Tasmania. A total of 113,164 diving hours were recorded across 125,536 individual fishing events (Table 1). Between 2012 and 2016, the Tasmanian Geo-Fishery Dependent Data (GFDD) program captured between 85 % and 90 % of...
The long-spined sea urchin, Centrostephanus rodgersii has expanded its distribution southwards from southern New South Wales, through Eastern Victoria, the Bass Strait Islands and down the east coast of Tasmania. In some areas of Tasmania abundance of C. rodgersii has increased substantially, even...
Over the next century, the marine ecosystems of south-eastern Australia are expected to exhibit
some of the largest climate-driven changes in the Southern Hemisphere. The effects of these
changes on communities and businesses will depend, in part, on how well fishing industries
and resource managers...
