Need

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.

Objectives

1. Develop a program for ongoing collection of biological samples and data of key range-shifting fish species using citizen science initiatives engaging with the recreational fishing community.
2. Develop geographically discrete life-history parameters for key range-shifting fish species in Tasmania to inform management decisions.
3. Determine the diet composition of key range-shifting fish species to refine parameterisation of an ecosystem model.
4. Utilise the Atlantis ecosystem model framework to predict ecological impacts of increasing abundance of key range-shifting fish species in Tasmania.
5. Develop species distribution models that utilise oceanographic climate change projections to predict the future presence and persistence of the key target species in Tasmania.

Summary

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.

Blue carbon and the Australian seafood industry: workshop

Need

The Australian seafood industry aspires to continue improving its sustainability in many areas, including reducing its carbon emissions and ultimately achieving carbon neutrality. The 2017 National Seafood Industry Leaders called for the industry to strive to become carbon neutral by 2030. There are many aspects to this, such as improving fuel efficiency and evaluating land transport options, but some emissions are inevitable. To offset these emissions, the seafood industry might choose to investigate carbon markets. Investments in blue carbon could also provide added value to the industry, say, through better fish nurseries, or through the social benefits of being seen to proactively nurture the ecosystems that support them. However, the mechanisms to allow the seafood industry to pursue this are poorly developed. Impediments include the paucity of blue carbon opportunities in existing regulatory markets, and uncertainty about the most appropriate financial mechanisms for blue carbon investment.

The industry would benefit from a clear guide that outlines the current (and likely future) opportunities, the risks, a realistic assessment of the benefits, and a set of options for potential investors to pursue. To facilitate this, we will hold a meeting of key seafood industry stakeholders: at this workshop we will inform stakeholders about the current state of knowledge and opportunities, ask the extent to which the industry aspires to be carbon neutral, and whether blue carbon investments are perceived to be relevant. We will identify the major impediments to the industry achieving its desired goals, and plan concrete actions that can be taken to achieve them. These will be compiled into a plan to inform the FRDC on what actions to invest in, and how much investment would be needed.

Objectives

1. Inform and understand aspirations of the Australian seafood industry with respect to carbon neutrality
2. Map the aspirations against current opportunities in Australia and overseas
3. Identify actions that can be taken by the seafood industry and the FRDC that will help move the industry towards meeting aspirations
4. Synthesise 1-3 into a plan that also identifies enablers and constraints that the industry needs to be aware of, and develop recommendations about the best steps

Summary

Several stakeholders within the Australian seafood industry have demonstrated strong leadership by developing carbon neutral business practices. In 2017, participants in the National Seafood Industry Leadership Program challenged the industry to become carbon neutral by 2030. In response, the Fisheries Research and Development Corporation (FRDC) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) hosted a workshop that invited key stakeholders and thought leaders from industry, government and nongovernmental organisations to discuss the overall attitudes of the Australian seafood industry to the concept of carbon neutrality, and to gauge aspirations for investment in coastal “blue” carbon offsets as a way of achieving carbon neutrality
 
Blue carbon offsets are not yet available in Australia, including (but not limited to) Australia’s Emissions Reduction Fund, but voluntary market opportunities exist overseas. Several Australian businesses are seeking to promote efforts to accelerate their development in Australia. Developing partnerships between the seafood industry and like-minded businesses, to address key uncertainties and knowledge gaps (such as uncertainty over tenure, lack of reliable demonstration sites, absence of key data such as carbon accumulation rates) is likely to be a fruitful option for maximising the future blue carbon opportunities for the seafood industry

A Better Way to Fish: testing the feasibility of tunnel net ‘fish trap’ gear in North Queensland

This study found that tunnel nets are technically feasible in this location. In spite of the weather conditions, the fishing gear remained intact and successfully captured significant numbers of marketable fishes. Importantly, SOCI species were released alive and in excellent condition, as were...

Effects of climate change and habitat degradation on Coral Trout

Fishes are at considerable risk from changing environmental conditions because they are, for most part, unable to regulate their body temperature. Exposure to high temperatures may therefore compromise critical biological functions, resulting in reduced performance, fitness and ultimately survival....
