In our recently published paper, we suggest that the depth range of many reef fish, including the rare and protected eastern blue devil fish, is being systematically underestimated due to sampling bias. We used remotely deployed video samples and recreational fisher observations, to provide examples of fishes living at depths much deeper than the depth range they are ascribed based on the scientific literature.

Voting is currently open in the Australian Society for Fish Biology Student Competition in Science Communication awards 2018 (five days left to vote!). This year there is $3000 in prize money up for grabs. Entry is via a short video showcasing the postgrads research and the public vote on senior (PhD candidates) and junior (Masters and Honours candidates) category entries. This year there is also an additional category that will run at the ASFB conference and will include 50% delegate votes and 50% judging panel votes in deciding the winner.
I have been involved in organising the competition the last few years (and as an entrant in the first year) and I have to say that the quality of the videos on offer this year is exceptionally high across the board. They are well worth taking some time to check out.
You can find all the entries and vote in both categories here. And I encourage you to also think about leaving a comment or two on the videos you enjoy – they take a lot of work to put together and getting feedback always helps make it worth it.
Mary Mackay is a PhD candidate (at the Centre for Marine Socioecology University of Tasmania, Australia) researching the role of incentives, regulations, and nudges in influencing compliance behaviour of marine resource users. I had a chance to catch up with Mary at the recent International Marine Conservation Conference in Malaysia and hear about the work she is currently doing and her recent publication. As it was so interesting, I then convinced her to stop by Fish Thinkers and share the details in the guest post below:
When push comes to shove in recreational fisheries compliance, think ‘nudge’
Common to recreational fishing research is a lack of official reported data, which makes it pretty hard to get a full idea of what’s going on. Continue reading
Tom Staveley is a Marine spatial ecology & PhD candidate at DEEP Stockholm University and he is currently putting the finishing touches on his thesis. Both of us are living the invandrare life in Sweden at the moment so I got a chance to catch up with him recently and managed to drag him away from the thesis for long enough to give us a run down (below) on some of the research he has been working on.
Fish Patterns in the Seasonal Seascape
Being a marine ecologist in Scandinavia certainly has its advantages: long summer days to do seemingly endless fieldwork, stunning surroundings and surprisingly lush underwater habitats (yes, I’m talking mainly about seagrass but we’ll get to that later). Even in the heart of winter a sublimely frozen wonderland of crisp air, still bays and snow-covered land- and seascapes never ceases to amaze. For the past few years, I have been exploring the coastal waters of western Sweden in the Skagerrak/North Sea focusing my research on seascape ecology – a relatively new branch of marine science focusing on broad-scale patterns and processes in the seas and oceans.
Fish Thinkers has just become an official project supporter of Australasian fishes, which as someone that has a
slight obsession with fish, I am rather happy about. Set up by the Australian Museum in 2016, it is a really nice example of a citizen science project that is open to all and it is getting lots of interesting results. Continue reading
Pregnant Sharks and Rays Abort Offspring When Fished – Guest post by Kye Adams
Have you ever seen a viral video of a shark or ray giving birth (e.g. River Monsters)? Unfortunately, it turns out these videos have a pretty dark explanation: There’s a fairly high chance the female is actually aborting her pups due to the stress of being caught. Continue reading
Curtis Champion is a PhD candidate at the Institute for Marine and Antarctic Studies – University of Tasmania. He stopped by the Fish Thinkers blog to give us a run down on some of the research he is working on.
Species on the move and a quick explainer about how range-shifts are commonly identified
Climate. Change. No doubt you’ve heard of the phenomenon. And while a small number of our political reps sporadically break into the headlines for criticising its reality, the global scientific community has been busy forging novel territory to understand its ecological consequences. This emergent field is most-commonly referred to as “species redistribution science” because plants and animals shifting where they live (generally towards the poles or up mountains) in response to changes in temperature is perhaps the most perceptible ecological effect of climate change.
