The PDRF will be expected to play a significant role in developing the project applications for CST, ABFA and AAGA and be involved in the development of strategic projects in the Theme as these develop and then be a lead scientist undertaking the designated research, in association with experts in aquaculture genetics and also from other disciplines (e.g. nutrition, aquatic animal health, larval rearing and systems design). The proposed project is likely to comprise a range of research activities focussed on the estimation of genetic parameters, the management of selection programs and the estimation of genetic gains. There will also be a range of complementary research activities addressing key constraints to optimisation of breeding programs.
The contributions of this PDRF will be directed at the CRC’s Program 1 – Value Chain Profitability, Outcome 1 – Increased profitability and industry value through efficient delivery of Australian seafood to the consumer; and Output 1.3 - removal or reduction of key production constraints in selected aquaculture systems. The focus in this area will be on milestones 1.3.1 (new genetic tools and/or appropriate breeding strategies developed for genetic management and improvement of at least two aquaculture species); 1.3.2 (genetic parameters estimated for key commercial traits; genetic improvement programs designed and implemented for at least two aquaculture species) and 1.3.5 (production efficiency gains from genetic, health management and nutritional interventions quantified to inform long-term strategies and estimate commercial benefits).Read moreRead less

Summary
Some examples of useful software tools needed to support breeding programs in the CRC would be: •Models to simulate selective breeding programs and to determine economic weights of key traits and optimise the breeding program design accordingly. • Relational database systems for effective, reliable recording, storage and output of relational data (pedigree, phenotypes, genotypes etc.) • Pedigree analysis software or procedures • Genetic analysis software or procedures • Soft ....Some examples of useful software tools needed to support breeding programs in the CRC would be: •Models to simulate selective breeding programs and to determine economic weights of key traits and optimise the breeding program design accordingly. • Relational database systems for effective, reliable recording, storage and output of relational data (pedigree, phenotypes, genotypes etc.) • Pedigree analysis software or procedures • Genetic analysis software or procedures • Software that assists development of multiple trait selection indices incorporating economic weights for key target traits • Software that helps guide mate selection (including optimum contribution selection tools)
Each breeding program in the Seafood CRC will ultimately need to know: •What type of software do other established breeding programs (in aquaculture and other primary production) require and use? • What software is already available, from where and from who? What problems do the tools address and what do they enable? • Which software tools are applicable or easily adapted to aquaculture? • What level of adaptation would be required for the adoption of existing tools into aquaculture and what resources (skills) would this need? • Which tools could address common problems across different aquaculture sectors? • What level of skill is needed to operate the software? • Does the software have good documentation and do the developers offer support services? • Is the software freely available, available at a price, available to partners or maintained as a trade secret? • Might it be useful to link to other breeding companies or organizations (aquatic, livestock or forestry) to access existing tools or expertise for developing such tools? • Are there initiatives underway or being planned that aim to develop useful new software for aquaculture and might the CRC be able to link to such initiatives?Read moreRead less

Summary
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 Nationa ....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 Read moreRead less
Geometry of wall-turbulence and its potential to advance scalable models. This project aims to unravel the connections between the statistical geometry of wall-turbulence and the dynamical interactions of its instantaneous motions. Predicting the complex behaviour of turbulent fluid flow over surfaces in relative motion is central to atmospheric modelling for climate and agriculture, and reducing the environmental effect of fossil fuel usage.

This project aims to unravel the connections between the statistical geometry of wall-turbulence and the dynamical interactions of its instantaneous motions. Predicting the complex behaviour of turbulent fluid flow over surfaces in relative motion is central to atmospheric modelling for climate and agriculture, and reducing the environmental effect of fossil fuel usage. Wall-turbulence statistics organise according to a predictable geometric structure, and the notorious complexity of turbulent wall-flow dynamics could be clarified through its inherent geometry. This project expects to construct a basis for predicting engineering and atmospheric wall-flows, which would enhance atmospheric flow prediction, reduce energy consumption and further environmental sustainability.Read moreRead less
Self-similar scale interactions in turbulent boundary layers. Predicting and controlling turbulent fluid flow next to a solid surface (the turbulent boundary layer) is of critical importance to ensuring a sustainable energy and environmental future. While recent research has yielded a clearer physical understanding of these flows, converting this understanding into tools useful to engineering practice remains a central obstacle.

Predicting and controlling turbulent fluid flow next to a solid surface (the turbulent boundary layer) is of critical importance to ensuring a sustainable energy and environmental future. While recent research has yielded a clearer physical understanding of these flows, converting this understanding into tools useful to engineering practice remains a central obstacle. The proposed research directly addresses this fundamental challenge by precisely connecting the eddy interactions of the turbulence to the mathematical equations that rigorously describe these flows. As such it holds breakthrough potential toward the development of turbulent boundary layer prediction and control schemes that do not rely on ad hoc models or assumptions.Read moreRead less
