Profiling and tracking change in Australia's seafood workforce: establishing a baseline workforce dataset
The project developed to address the call for EOI recognises that the seafood workforce is diverse and operates within a changing natural, technological, and socioeconomic environment, providing unique challenges and opportunities. The seafood workforce also, however, operates within the wider Australian economy where rural and regional employment, small-medium business operations, and increasing value-adding opportunities are common topics of interest. The project proposes to provide a comprehensive assessment of the current data framework, make recommendations for improving it, and develop a baseline workforce dataset. The focus will be on the potential to use existing sources of data (particularly administrative data collected by government institutions and data that is required to be collected) and how and when those need to be effectively complemented with additional data. Administrative data are confidential and access limited as is the variety of seafood industry data often collected. Accessing administrative data is explicitly part of this proposal and identifying the sources of, and the type of data available, from industry surveys.
Opportunities and impacts of range extending scalefish species: understanding population dynamics, ecosystem impacts and management needs
Species-level responses to ocean warming is a priority research area as they underpin the structure and function of marine ecosystems and the productivity of fisheries that operate within them.
There are a number of range extending species that have become increasingly abundant in Tasmanian waters, providing new fishing opportunities for recreational and, to a lesser extent, commercial fishers. Species in this group include Pink Snapper, King George Whiting and Yellowtail Kingfish. While King George Whiting are known to spawn off the north coast it is unclear as to whether the other species have or are likely to become established as self-sustaining populations in Tasmanian waters or simply persist as spill-over from populations that are centered off mainland Australia. If the former is the case, it will be especially important to consider population attributes such as growth, mortality and reproductive dynamics relevant to the Tasmanian populations when developing and refining management arrangements to maximise the opportunities these 'new' species bring.
In addition, the broader ecosystem impacts of such range extending species, including competition with resident species at similar trophic levels, are unknown but could have consequences for other recreationally and commercially important species. Understanding these relationships will have benefits for the assessment and management of the Tasmanian recreational fishery more generally.
Final report
This work set out to quantify the biology and diet of three key range-shifting species in Tasmania with both recreational and commercial fishery value. The project was heavily reliant on engagement from the recreational fishing community and multiple citizen science initiatives, as well as historical data.
The information collected was used in modelling to predict how suitable habitats for each species may shift under future climate change projections. The work also indicated the potential changes to the ecosystem (such as food web) if these species’ ranges were to move.
