New Project : Trophy Murray Cod: taxidermied Murray Cod and environmental change in the Murray-Darling Basin 

Matt O'ConnellMatt O'Connell commenced his PhD in January 2017.  He will be looking for "trophy Murray Cod",  a search which will take him to many remote and regional communities around the Murray-Darling Basin. The project already has a public group Facebook Page "Stuffed Murray Cod in Pubs" with over 200 interested members. 

Initial research has already identified where some 100 or so trophy Murray Cod could be in the Basin. Matt will build on that knowledge with a citizen science aspect of his research. In addition, Matt plans to collect information from and about the Cod, which includes samples of DNA, 3D scans and as much information as possible about the size, when it was caught, who caught it, where it was caught and what people think about it being a trophy.

Once the data about the Cod has been collected, Matt will be correlating it with other information i.e. water quality to come up with some trends on how Murray cod are travelling in the Murray-Darling Basin.

Background

FishlarveThe Fish Ecology Collaborative Research Unit (FECRU) aims to foster rigorous science in freshwater fish ecology in Australia, and more specifically the Murray-Darling Basin.

It is establishing partnerships with government natural resource agencies interested in the management, conservation or restoration of fish populations and the ecosystems they occupy and other research centres such as the Murray Darling Freshwater Research Centre.

Its objectives are to:
1) Provide a hub for research collaboration that combines fundamental science with applied conservation, environmental and fisheries management.
2) Educate post-graduate (Honours, MSc. and PhD) students and support post-doctoral research and training.
3) Influence public awareness, management and conservation of fish populations and aquatic ecosystems through the dissemination of science.

Mission

The mission of the FECRU is to carry out rigorous and independent science, underpinned by ecological concepts, to help address the most challenging problems related to the management and conservation of fish and aquatic ecosystems.

Research model

Research undertaken by the unit will be expected to improve our knowledge of the ecosystem role of fish, so that management, conservation and restoration strategies are based on rigorous scientific evidence, with a view to long-term sustainability.

The unit will establish co-funded collaborative research projects between government natural resource management agencies and researchers at CSU. Projects will be developed and undertaken by post-graduate and post-doctoral researchers in collaboration with academic staff at CSU and a state or Commonwealth government partner.

Projects of mutual interest to CSU and partners are expected to traverse fundamental and applied research themes focusing on fish in the broad areas of ecology, restoration fisheries management, biodiversity conservation, environmental monitoring,
management or assessment.

By virtue of CSU's inland geography and research track-record, many projects will focus on freshwater systems in the Murray-Darling Basin. However, research that will generate broadly applicable and fundamental new insights, regardless of geographic area, will receive priority.

Engagement

Larval Fish Conference

Continuing his long-term association with the University of Vienna, Paul was one of the organisers of the 39th Annual Larval Fish Conference held at the university in July 2015, where the paper Humphries, P.,  Kopf, S., Kaminskas,T., Keckeis,H., McCasker,N., Stoffels, R., Bond,N. & Watts,R. Integrating life history theory and dispersal in riverine fishes, was presented.   While in Austria, Paul also ran a Masters Field Course and class.

Citizen Science - Stuffed Murray Cods in Pubs

This project, which got off the ground with a CSU media release in February last year, certainly generated a lot of media interest including a segment  on the ABC's 7.30 Report on April 4.It took off with a Bang and now there  almost 200 members in our facebook group, 122 locations of stuffed Murray cods and close to 150 fish, mostly in pubs and sporting clubs around the Murray-Darling Basin.

 Freshwater Research News  by adjunct Dr Kevin Warburton The newsletter's target audiences
are aquatic resource managers, educators or students interested in aquatic environments, people from organisations involved in environmental protection, and aquatic researchers keen to stay abreast of developments outside their specialist areas. It contains articles, using non-specialist language as much as possible, that summarises the background and significance of recently published research findings with special attention to novel ideas, new interpretations, and interdisciplinary connections involving the freshwater environment.
