A global review on implications of plastic in seafood
Microplastics are commonly consumed by seafood species however, there is still limited understanding of the effects and implications that microplastics may have on the fishing and aquaculture industry. This project summarises research on the effects that microplastic may be having on seafood...

Minor use permit for oxytetracycline in non-salmonid finfish
There are no registered or permitted antimicrobial products approved by the Australian Pesticide and Veterinary Medicine Authority (APVMA) for treatment of bacterial infections in finfish. This project developed an application for a minor-use permit (MUP) for the use of oxytetracycline (OTC) to...

SPECIES
The Australian Southern Bluefin Tuna Association (ASBTIA) operates in shelf and offshore waters of the Great Australian Bight (GAB). In recognition of the exposed nature of the offshore GAB environment, ASBTIA have requested information to better understand the climatology of the physical meteorological and oceanographic conditions which contribute to the ‘sea-state’ and ocean conditions at a deep water petroleum permit location in the Great Australian Bight.
This project will provide the oceanographic services required to identify, access and analyse long-time series of relevant met/ocean parameters and statistically describe their climatology in order to better understand the ‘sea state’ characteristics of the GAB and how they compare with sites located within other international oil production regions.
1. To understand the exposure and sea-state of the Great Australian Bight relative to three other regions of interest.
3. For each location and parameter (detailed in methods), provide a summary of monthly sea-state climatology described by the mean, variance, frequency and intensity.
3. For each location and parameter, determine of the probability of extreme events to occur at fixed return periods.

This report provides a detailed characterisation, assessment and prediction of the meteorological and oceanographic conditions that will be encountered by, and have the potential to impact, future petroleum activities in the Great Australian Bight. In the absence of direct, long-term observations, the improved understanding of the offshore Great Australian Bight environment generated by this study is critical to the assessment of the suitability of the Great Australian Bight for hosting offshore petroleum industry and response planning necessary to mitigate any environmental impacts which may result from associated activities.

Need
The National Carp Control Plan (NCCP), operating within the Fisheries Research and Development Corporation (FRDC), is developing a plan for potential release of the virus known as Cyprinid herpesvirus 3 (CyHV-3) to control invasive common carp, Cyprinus carpio, in Australian freshwater environments.
If the carp virus is approved for release, major carp mortality events are likely. It is necessary to better understand the potential ecological consequences of such events, and hence to inform clean-up strategies for carp biomass post-release. One potential risk is hypoxia or anoxia in the river system associated with microbial degradation of carp carcasses in accumulation hotspots. As carp inhabit a range of habitat types, including reservoirs, lakes, river and wetlands it is necessary to understand the oxygen dynamics in each of these habitats so that the risk can be adequately managed.
Objectives
The aim of this project is to predict the impact of mass carp mortality on the dissolved oxygen concentration of wetlands, rivers and floodplain habitats. This requires assessment of how the key processes that affect oxygen in these different environments respond to changes in hydrologic flushing, temperature and other environmental attributes, and consideration of the likelihood of carp accumulation.
This modelling will be used to inform the cost-benefit analysis of the carp control program of FRDC, aid assessment of what ecological and infrastructure assets are at greatest risk, and determine whether flow can be used as a strategy to re-aerate water in the event of hypoxia.

This investigation was undertaken by the University of Adelaide and the University of Western Australia as a part of the research priorities for the National Carp Control Plan. While proposed biological control agents to reduce carp numbers may have positive impacts to aquatic ecosystems, it is possible that wide-spread carp mortality may present considerable risks to the quality of water in Australian wetlands and waterways that need to be managed. Specifically, large-scale carp mortality in aquatic systems will lead to the generation of:
- High oxygen demand
- A pulse of fish-derived nutrients
There is a concern that these impacts will generate water quality risks for humans and ecosystems associated with persistent low oxygen (hypoxia and anoxia), excessive levels of ammonia, and the build-up of cyanobacteria blooms, including the associated challenges of cyano-toxin release, and further deoxygenation during bloom collapse. This study modelled risks to water quality that could arise from carp inputs to a representative set of Australian waterways using data from field and laboratoty trials.
