Dr Adam Kerezsy, aquatic ecologist, talks about the unique desert spring environment supporting the Red Finned Blue Eye.
There's much to admire about the work of Adam Kerezsy. A former teacher turned aquatic ecologist. Here's a couple of podcasts to listen to about this work and I recommend your grab a copy of his book Desert Fishing Lessons
Protected areas such as Alpine National Park and the Great Barrier Marine Park are a crucial tool for conserving wildlife on land and in the sea. But there is no similar protection for freshwater ecosystems in the world’s driest continent, Australia. Why not?
Wetlands and rivers need water – not least in the case of Australia’s biggest river system, the Murray-Darling Basin, which has been the target of an “environmental watering” plan designed to preserve its water levels and quality.
Everyone knows what a yabby is, don’t they? Well, you would be surprised. Those charming little critters with nippers in your local dam may belong to the species Cherax destructor, also known as the common yabby, but they may also be juvenile spiny crayfish (genus Euastacus), adult burrowing crayfish (genus Engaeus) or another species within the genus Cherax, including gilgies, marron and redclaw.
I refuse to call these critters Water Rats. Too many Australia mammals just get labelled "rats". It generates negative thoughts toward Australian Wildlife and shows a big problem Australia has in trying to conserve our natural biodiversity, when much of our precious wildlife are considered vermin.

This is another ABC Radio National - Off Track podcast. This podcast looks at the work of Secret Creek near Lithgow, west of Sydney, which is working on a breeding program with the Eastern Quoll. If you are interested in the subject of predators in the Australian environment, you may be interested in the work of Rewilding Australia.
Here is another great podcast from ABC Radio National program - Off Track. It's a soundscape of dusk to night in the eucalyptus forests of Victoria. Ecologist David Lindenmayer, from the Australian National University is your guide.
While the rivers of northern Australia and the Murray-Darling Basin are renowned for their iconic, large-sized, fish species such as Murray Cod and Barramundi, the temperate inland waterways of Tasmania are home to numerous “minnow-type” fishes.
Australia has around 300 species of freshwater fish. Many people are aware of iconic species like Australian Bass, Barramundi and Murray Cod, but there a many small fish that deserve our attention. Here is the Southern Pygmy Perch.
Australia’s urban waterways are often polluted and sick. They suffer from a condition called the “urban stream syndrome”. A common factor that contributes is contamination from sewage.
Since the discovery of the Pacific Garbage Patch in 1997, which is predicted to measure twice the size of Texas, five more have been found across the world’s oceans with the Atlantic gyre predicted to be even larger. This plastic takes thousands of years to degrade, remaining in the environment to be broken up into ever smaller fragments by ocean currents. The gyre stretches from the coastlines of California to the shores of Japan. Recent studies have estimated 46,000 pieces of plastic per square kilometer of the world’s oceans. The number of plastic pieces in the Pacific Ocean has tripled in the last ten years and the size of the accumulation is set to double in the next ten. Sea Chair is made entirely from plastic recovered from our oceans. Together with local fishermen, Studio Swine collects and processes the marine plastic into a stool at sea.
A colleague is working on developing some identification resources using the LUCID key which will include a smartphone app... watch this space. He showed me a LUCID Key app currently available for android and iOS which is for the identification of Insect Orders.
Apps which have keys to assist your identification skills are fantastic to ensure proper identification of fauna and flora and can be carried into the field.
Recently whilst running a workshop on the identification of aquatic macroinvertebrates I referred to the mouth parts and hunting abilities of the Order: Odonata (dragonflies and damselflies). Watch this video and be aware of what to look for on when next identifying Odonata
