Australia’s fisheries span a large area of ocean. Australia has the world’s third largest Exclusive Economic Zone (EEZ), with an area of over 8 million km2. This zone contains mainly Commonwealth managed fisheries, with State jurisdictions mainly in coastal waters up to the 3 nautical mile limit. Australia's total wild-catch fisheries gross value of production is $1.6 billion, of which 28% is from Commonwealth fisheries and 72% from the smaller coastal inshore fisheries managed by state jurisdictions. The wildcatch fisheries sector employs about 10,000 people across Australia (https://www.awe.gov.au/abares/research-topics/fisheries/fisheries-and-aquaculture-statistics/employment).

The commercial fishing industry has a network of thousands of vessels working mainly in inshore waters around Australia. They can supply a potential platform for extensive and fine scale spatial and temporal monitoring of the waters of the continental shelf (0-1200m), from the surface to the ocean floor. Given that their livelihoods depend on it, they have a keen understanding of oceanographic conditions with respect to fish behaviour, feeding and spawning and the various oceanographic factors that may influence this. In some fisheries (e.g. surface tuna longlining), fishers eagerly seek and use readily available fine-scale oceanographic data such as sea surface temperature and sea level, to improve their targeting and achieve higher resultant catch rates. For many other fisheries, however, it is the fine-scale sub-surface oceanographic conditions (feed layers, thermoclines, temperature at depth etc) that have a critical influence on their fishing dynamics. Unfortunately, this type of oceanographic data is far less readily available. Although fishers and scientists know these factors are important, the time series of fine scale spatial and temporal data relevant to fishery operations is not available to include in stock assessments. As a result, it is often assumed that variations in catch rates reflect changing stock abundance, when it may simply be a result of changing oceanographic conditions.

Marine scientists collect a vast range of oceanographic data using satellites, subsurface drones, and static and drifting buoys. Sea surface data, however, is much easier and more cost-effective to collect at high spatial and temporal resolutions than sub-surface data. Hence, understanding of sub-surface oceanographic conditions tends to be derived from modelling more than actual measurement. This may be sufficient at a wide-scale global or continental level, but it is not adequate at the fine-scale spatial and temporal resolution required for fisheries management.

The use of commercial fishing gear as a research data platform has been increasing in popularity internationally (https://www.frontiersin.org/articles/10.3389/fmars.2020.485512/full). A number of groups in Europe have been doing this for a decade (e.g Martinelli et al 2016), and New Zealand are also now involved (https://www.moanaproject.org/te-tiro-moana). However, this approach has yet to be implemented in Australia in a coordinated way. In particular, our approach dictates open access data served through the IMOS Australian Ocean Data Network (www.aodn.org.au) that can be collected once and used many times.

In this project we intend to instrument seafood sector assets (e.g Trawl Nets, longlines, pots) with fit-for- purpose quality-controlled (QC'd) temperature/pressure sensors to increase the sub-surface temperature data coverage around Australia’s shelf and upper slope regions (0-800m) at low cost. Not only will this assist in the collection of data at relevant spatial and temporal scales for use by fishers, but it will also provide a far more extensive level of QC’d data to oceanographers in near real time (NRT) for evaluation and ingestion into data-assimilating coastal models that will provide improved analysis and forecasts of oceanic conditions. In turn, this will also be of value to the fishing sector when used to standardise stock assessments.

Australian and New Zealand Rock Lobster is a high value product that has strong recognition in their local and export markets. There is significant capital investment across the combined jurisdictions of the Trans-Tasman lobster fisheries. As with most other wild caught fisheries and seafood sectors Trans-Tasman lobster fisheries face similar challenges in regards to, sustainability, threats to / competition for the resource and resource access, product quality and food safety, implications from aquaculture production and applying and taking advantage of new and emerging technologies. In addition to these common industry issues, lobster fisheries produce a product that is predominantly for live export which adds further challenges such as barriers to trade and trade agreements, complex supply chains and understanding the ‘what and where’ of new market opportunities.

Well organised and educational forums such as Trans-Tasman Rock Lobster Congresses enable a sharing of information and a collaborative approach to addressing challenges and sharing successes. Since first being held in 1999 the biennial Rock Lobster conferences have become the pre-eminent forum for the respective Trans-Tasman lobster industries to consider and address the many challenges across the supply chain. There is never a shortage of key issues and topics to address and bring together in a common theme to deliver a successful Trans-Tasman Industry Congress that has the support of all the key industry bodies and wider stakeholders.

The history of successful Trans-Tasman Industry Congresses, speaks for itself.
Trans-Tasman Congresses have well established support of all the key industry bodies and wider stakeholder interests with all lobster producing jurisdictions having now hosted an event. This history combined with the experience, existing contacts, establishing themes, producing engaging programmes, having informative exhibitions, attracting quality keynote speakers - both local and international, continuing sponsorship from service providers and the ability to attract the general support of industry ensure there is a pool of support and knowledge to deliver successful congresses

Initial Contributions (2023):
• Total combined initial contributions will be to a maximum of $30,000.00.
• Request a cash contribution from the NZRLIC.
• Request a contribution from the Eastern Rock Lobster Industry.
• Contribution from the SRL IPA.
• Contribution from the WRL IPA.

Proposed Governance Arrangements:
• The Managing Entity (ME) i.e. the industry body responsible for administering the congress in a particular year, will be responsible for holding and managing the ‘kitty’ of funds.
• ‘Surplus’ funds will be used to fund the administration, hosting and attendance of any planning meetings conducted in the ‘interim year’, this process will be managed by the ME responsible for hosting the most recent (past) Trans Tasman Congress.
• PI & Co-Investigators will discuss and confirm the amount required for future initial contributions.
