  Shark alert: primaeval predators in need of protection (series)
Why the top predators of the oceans are losing the battle for survival with Earth's top predator - humankind.

Tackling the feral Fish Problem Dr Dean Gilligan, from the NSW Department of Primary Industries, explains why everyone will be hooked by a new citizen project, Feral Fish Scan. Monitoring in NSW and particularly in the Murray-Darling Basin for nearly 20 years has shown pest fish emerging as an immense problem in our river systems. Common carp, for instance, now makes up 93% of all fish biomass in the Murray-Darling basin.

  Fish parenting: parents know best
Parents know best Dr Jenni Donelson, Chancellor’s Post Doctoral Fellow in the School of Life Sciences at the University of Technology Sydney, explores the effects of climate change on coral reef fish. Parental effects are important to examine to see whether offspring perform better or worse in different climate conditions depending on their parents’ environment. Like many animals the gender of offspring is not pre-determined at birth in fish and some reef fish will transition between genders at different life or size stages. For fish, warmer environments means that more juveniles will become male but parents can change this gender ratio.

  Breeding obvious - protecting migratory fish
Breeding sites for migratory fish must be preserved, to protect their reproductive behaviours. Breeding aggregations are special breeding places to which fish migrate each year in order to reproduce. This is not common fish behaviour since many species breed in the habitats where they live. The migration seems to be important in helping to increase their survival, including their offspring. For example, the chosen spawning site may have better protection from predators, a different food supply, different water currents. The same sites are returned to with each season’s migration and often may be quite distant from the home range. 

  Breeding like rabbits?
Dr Becky Fox, Chancellor’s Post-Doctoral Research Fellow in the School of Life Sciences at the University of Technology Sydney, investigates breeding aggregations in an important herbivorous fish on coral reefs – rabbit-fish.

  The catch about fishing is...
Fishes experience pain. People’s perception of animal intelligence correlates with their perception that the particular animal will be able to feel pain. Fish are low on the intelligence scale according to people’s perceptions; hence they also believe that they do not feel pain. This, of course, flies in the face of reality, one neurosurgeon likening such beliefs to flat earth adherents.

  A new angle on fish research
Dr Jodi Frawley discusses 'Talking Fish' an innovative 18 month research program that was organised by the Murray-Darling Basin Authority.

  What has sustainability to do with the price of fish?
Dr Kate Barclay, Senior Lecturer for the Global Studies Program at the University of Technology Sydney, is a fisheries social scientist with expertise in the Asian-Pacific region. Here she casts a net on aspects of the production and trade of canned tuna.

  Do fish sleep? Waking up to new research
Dr Culum Brown looks at the science of sleep for fish

  How Smart ARE Fish (series)
Recent research about fish cognition and behaviour suggest that many behaviours and abilities regarded as signs of human intelligent are not unique to people.

  The links between fish personality, behaviour and survival (series)
The more researchers look, the more obvious it becomes that other species have their own spectrum of personality types and styles. For fish, there are clear links now known between different personality types and their very survival, as well as the influence of environmental factors such as temperature.
