Innovative Solutions For Aquaculture: planning and management - addressing seal interactions in the finfish aquaculture industry
Capability & Capacity: 2024 Electric & Hybrid Marine Expo North America and Conference
Providing opportunities for fishing and aquaculture stakeholders to engage with the latest global information and technology, learn and network from leaders, innovators and practitioners in the electric and hybrid marine space is key to enabling innovation and adoption. Participants will experience and engage with technology, approaches and people via the expo and conference program.
Through attending, participants will build their capabilities and share knowledge with peers/stakeholders to inform, enable and drive change in Australia. The project intends to maintain momentum through this investment, empowering stakeholders to communicate and extend their experiences to contextualise opportunities for Australia and encourage future participation and attendance at similar events.
Final report
I note that the US Expo was of a much smaller size than the European Expo and did not have the displays and working models available to interact with. There is no doubt that a visit to the European Expo for Seafood industry participants would be very valuable. This should be targeted at those parts of industry than could not attend the US forum due to season dates ( ie Trawl).
The participation of Dr Jennifer Marshall gave those attending a link into the FRDC executive and the relationship will be further strengthen by her attendance and interaction with the team.

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.
