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....

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.

Need

As identified in the EOI scope and from previous FRDC and other research, there are multiple needs for further information on energy use and greenhouse gas (GHG) emissions in the Australian fisheries and aquaculture sectors (F&A).
Firstly, at the top-level, a national account of these sector’s performance is necessary to provide a clear determination of the overall F&A contribution within the Agriculture, Forestry & Fishing Industry classification (AFF Industry) classification within National Inventory Data. The AFF Industry is second largest emissions sector and there is a need to disaggregate the F&A sector from the broader agricultural data, and to also develop industry baselines against which further performance can be measured (and potentially benchmarked against other sectors).
Second, there is a need for sub-sectors (specific managed fisheries or industry groups) as well as individual companies to be able measure, assess and then potentially manage their own energy use and emissions.
Finally, once companies, subsectors and the F&A sectors have data, there is a need for education and tools to assist them to improve energy efficiency and profitability, lower emissions and related risks but also importantly how to create positive engagement with stakeholders, particularly customers becoming more discerning in product selection based on carbon footprint, to maintain competitiveness in consumer protein selection decision-making.

Objectives

1. Program 1: Establish energy use and GHG profile of Australian F&A sectors
2. Program 2: Develop and self-assessment tool for Australian F&A sectors energy efficiency and GHG
3. Program 3: Develop a toolbox and examples for emissions reduction opportunities in the fisheries & aquaculture sectors

Summary

This project is the first examination of the total carbon emissions of the Australian fishing and aquaculture (F&A) sectors and component seafood production industries. To date, some work had been done on energy consumption and efficiency improvements, but the carbon emissions of the Australian F&A sectors had never been calculated.
 
In Australia’s National Greenhouse Accounts, emissions from the F&A sectors are currently included within the aggregated ‘agriculture, forestry and fishing’ segment. This segment is the third largest in Australia’s inventory, and the ‘fishing industry’ data is overwhelmed within the large, aggregated datasets of these combined sectors and therefore often unintentionally overlooked.
 
However, measuring the carbon footprint of the F&A sectors was a complicated task that required an account of all the emissions generated directly and indirectly by the sectors. This included fuel burnt directly to power fishing vessels, to purchased electricity, refrigeration emissions and the emissions from services and products bought from external suppliers such as bait and aquaculture feed. The study measured the carbon emissions and energy use of Australia’s largest F&A producer industries, which together constitute about 82% of Australia’s domestic seafood production by gross value of production (GVP). While some of the other industries that make supply chain inputs to the F&A sectors are discussed (such as aquaculture feeds and fishing bait), the project focus is on the Australian seafood primary producers.
 
The information is a vital step in providing a competitive advantage for seafood as a low- emissions protein. Seafood consumers are increasingly wanting to know the stories behind the products they’re buying, including efforts by fishers and farmers to reduce their carbon footprint. It also highlights how seafood production may need to adapt in the future. 
 
As part of the project work, three GHG emissions calculator tools were developed to help fishers and farmers better understand what drives their GHG emissions and how to measure them. And once they have been measured, what can be done to better manage emissions, and utilise the information in their operations and customer discussions.
 
The project has identified five recommendations and opportunities for government departments and agencies to update and improve their GHG emissions reporting methodologies for the fishing and aquaculture sectors.

Need

Much effort has been placed over the last couple of decades on the development of harvest strategies, stock assessments, risk assessments and the strategic use of ecosystem models to facilitate meeting the needs of the Commonwealth’s Harvest Strategy Policy. A focus on modelling to improve fisheries management has required effort towards method development. However, little effort has been made towards revisiting and updating the biological parameters that fundamentally underpin such modelling (e.g. growth rates, age and size at maturity, natural mortality rates, dietary information, mixing rates and stock structure) and the tools or methods used to derive them. As a result, most models now rely on parameters and community dietary data derived from information collected during the 1970s-1990s, (e.g. available maturity ogives for blue-eye trevalla are over 20 years old), or information that is borrowed from other regions or species. Whether such old or borrowed values are now representative for commercial Australian fish species is unknown but many factors point to major changes occurring in our marine environment. Australian waters in the south east and south west are climate hotspots and, overall, Australian waters have warmed faster than the global average. Key components of the productivity of marine fish (growth, maturity, and recruitment) are expected to be undergoing directional changes under a changing climate and it is entirely possible that there have been changes in fundamental productivity parameters for some Australian stocks. The reliance of current assessments on what is likely to be out-of-date information leads to increased uncertainty, which propagates into management decisions. Without an understanding of any changes in biological parameters and how any change might impact assessment frameworks, determining whether current management measures are ensuring sustainability becomes highly uncertain.

Objectives

1. Identify the origin of current biological information used in assessments of species (including empirical stock assessments and ecosystem modelling efforts) carried out under the Commonwealth Harvest Strategy Policy, including the pedigree of the information (provenance, age, appropriateness of methods used).
2. Assess the implications and risks associated with using dated and borrowed information in assessments currently used for informing fisheries management, including the scale of any risks and the species for which a change in biological parameters used in assessments has the greatest impact.
3. Identify the methods that might be applied to update priority biological parameters, including a review of the efficacy and applicability of novel methods and approaches developed in recent years.
4. Articulate a work plan including appropriate sampling regimes required for updating priority biological parameters used in assessments for those species identified as being at most at risk.
