Automation of species recognition and size measurement of fish from underwater stereo-video imagery. The project aims to develop algorithms to automate the processing of stereo-video images recorded to count and measure the size of fish. This will improve husbandry and monitoring for finfish aquaculture at reduced costs, create technology export for industry partners, and develop cost effective, non-destructive finfish sampling tools for marine agencies.
Understanding climate and harvest induced changes in fish life histories. This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems.

This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling. Expected outcomes include fundamental insights into how human-induced environmental change affects fish growth and maturation, and a subsequent critical evaluation of the sensitivity of fisheries models to trends in these life-history traits. This should provide significant benefits to fisheries and ecosystem management, ensuring they remain productive and resilient in a time of rapid environmental change.Read moreRead less

Reliable and accurate statistical solutions for modern complex data. This project aims to develop novel methods for reliable and accurate statistical modelling with modern, complex correlated and error-prone data.

This project aims to develop novel methods for reliable and accurate statistical modelling with modern, complex correlated and error-prone data. The project expects to make significant strides towards future-proofing statistical data analysis, equipping practitioners with a suite of robust and computationally efficient methods which provide confidence in the stability and reproducibility of results obtained, while offering guarantees on their transferability over a range of populations. This will provide important benefits as they are applied in predicting endangered marine species for fisheries conservation, and in enhancing our national understanding of the relationship between education achievement and financial success.

Immediate and delayed changes to survival, physiology, reproduction and movement of chondrichthyans following capture stress. Many sharks and rays are negatively affected by the impact of fisheries capture, with unknown consequences. The project will measure changes to survival, physiology, reproduction and behaviour following capture to better understand and manage the impact of fisheries on these animals. This information is vital for their effective conservation.
Understanding the effect of small-scale ocean process on tuna populations – a new tool to forecast tuna distributions for use in fisheries management. The western and central Pacific Ocean supports the world’s largest tuna fishery with catches contributing up to 40 per cent of revenue for many Pacific communities. These nations are dependent on these fisheries for livelihoods and economic development. Continued sustainable management of this valuable resource in the face of rapid population grow ....Understanding the effect of small-scale ocean process on tuna populations – a new tool to forecast tuna distributions for use in fisheries management. The western and central Pacific Ocean supports the world’s largest tuna fishery with catches contributing up to 40 per cent of revenue for many Pacific communities. These nations are dependent on these fisheries for livelihoods and economic development. Continued sustainable management of this valuable resource in the face of rapid population growth and climate variability and change is a challenge. Using observationally derived information of skipjack tuna, the project aims to develop a novel tuna behavioural model. This is intended to be integrated into a state-of-the-art biophysical model at resolutions capable of reproducing critical meso-scale processes, providing projections of tuna distributions that aim to aid in developing sustainable management practices.Read moreRead less
A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species.

Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit in areas where a strong need exists for conservation of prey species with economic importance too low to justify expensive at-sea research.Read moreRead less
Mitigating Seal Interactions In The SRLF And Gillnet Sector SESSF In South Australia

Summary
South Australia contains 80% of the endemic Australian sea lion (ASL) population, where substantial fishing effort in the gillnet sector SESSF (~20,000 km net-lifts/year) and SA RLF (~1.5 million pot-lifts/year) increase the risk of fatal interactions.
A recent risk assessment (FRDC 2005/077) identified that subpopulations of ASL are highly vulnerable to even low-level bycatch from fisheries, with >40% of subpopulations at risk of extinction from as little as 1-2 additional female deat ....South Australia contains 80% of the endemic Australian sea lion (ASL) population, where substantial fishing effort in the gillnet sector SESSF (~20,000 km net-lifts/year) and SA RLF (~1.5 million pot-lifts/year) increase the risk of fatal interactions.
A recent risk assessment (FRDC 2005/077) identified that subpopulations of ASL are highly vulnerable to even low-level bycatch from fisheries, with >40% of subpopulations at risk of extinction from as little as 1-2 additional female deaths/year over a 20-25 year period. The risk assessment identified that the current high proportion of depleted subpopulations of the species may be entirely due to sustained low-level bycatch by commercial fisheries.
ASL are listed as a threatened species under the Commonwealth EPBC Act, and a recovery plan has identified bycatch from bottom-set gillnet and rock lobster fisheries as the most significant anthropogenic contributor to the species’ lack of recovery. As such the development of measures to mitigate interactions with sea lions forms the most pressing ESD issues for these fisheries.
ESD assessments of both the gillnet sector of the SESSF and SARLF fisheries have identified interactions with seals as a significant issue. These assessments make at least seven recommendations to address protected species interactions (including seals), but little if any progress has been made to address these to date.
In order to have southern rock lobster taken from South Australian waters placed on the list of exempt native specimens for export under Part 13 and 13(A) of the EPBC Act, there is an imperative to address these ESD recommendations, as failure to do so may jeopardise current and future export exemptions. Objectives: 1. Develop and assess methods for mitigating sea lion interactions with southern rock lobster pots 2. Develop spatial management options for reducing bycatch to high-risk sea lion subpopulations in the gillnet SESSF, and make recommendation on spatial management options to Shark RAG 3. Assess the significance of ASL bycatch in the high-risk regions of the gillnet SESSF to provide support for spatial management options developed in objective 2 4. Develop performance indicators to evaluate the effectiveness of the different mitigation options developed for each fishery Read moreRead less
