Listening to the unseen horde: Parasites and environmental change in the Murray Darling Basin

Research output: Other contribution to conferenceAbstractpeer-review


Parasites are usually invisible, therefore, although it is estimated that over 75% of the earth biodiversity are parasitic species, their impacts on our ecosystems are frequently overlooked. This oversight is more pronounced when it comes to parasites in aquatic systems, due to significant shortage of experts in the country. This presentation starts with an overview of the importance of parasites in our environment. It then presents some of our research findings showing that there has been recent dramatic changes in populations of some parasites in the Murray Darling Basin which may be due to climate change and anthropological factors. The absence of these parasites may sound positive; however, it may indicate a serious decline or extinc tion of other microscopic non-parasitic species in the region too. A significant decline or extinction of a parasite may also create new ecosystem niches for other invasive parasitic species to exploit. Understanding the factors behind the absence of these species are highly informative for the sustainable management of our water systems.

OtherThe goal for ASFB 2019 is to showcase and celebrate the place that the wonderful world of fishes has in the hearts and minds of people spanning a range of cultures, backgrounds and perspectives.

The conference program has workshops, special events and sessions that will explore how to effectively communicate via the visual arts, digital media, and the spoken and written word, bringing new understanding and inspiration to the millions of people who value and depend on fishes for their wellbeing.
