Australasian Fishes: We Want Your Fish (Sightings)!

original John Sear 4

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.

Pregnant Sharks and Rays Abort Offspring When Fished

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

Species on the move

A prediction of the preferred environmental habitat for the range-shifting yellowtail kingfish (Seriola lalandi) for March 2008, based on a combination of preferences for sea surface temperature, current speed and sea surface height.

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.

The Stand: Why are we scared to go in the water?

“The chances of falling victim to a shark attack are incredibly slim, yet these majestic creatures represent one of mankind’s greatest fears. In a world where every shark encounter is front page news, can we fight back against this distorted perception?”

Tagging along with the Coastal Carolina University Shark team

 

Caroline (from over at CCU Shark Research Team) stopped by the Fish Thinkers blog to give us a run down on where her research is headed and a sneak peak into the world of grad student shark research in the United States. Continue reading

Fish Thinkers online: 2015 in review

I was reading one of the bigger ecology blogs that I find myself returning to fairly regularly and they posted a review of their blog year, mostly for themselves to reference.  I found it interesting so went to have a look at our own blog and social media stats. I thought  I’d post a fish thinkers summary mainly as a record for myself but also on the odd chance anyone else is vaguely interested (its also a sneaky way to kick off a year in which I plan to post on here more regularly).

Dragging the chain – does anchoring by large ships impact our marine life?

I’m excited to announce that I’ll be joining a multidisciplinary team of researchers, supported by UOW’s Global Challenges program, to investigate the potential impact of large ships anchoring on our marine life and seafloor habitats.

As an island nation, we are heavily dependent on shipping, with large ships transporting 99% of our trade by volume. Prior to entering our ports these large vessels may anchor in deep water, often for many days, waiting for their turn to exchange cargo.

Now when I say ‘large’ I mean freakin huge (see pic below). These ships are between 200-300 metres long and to anchor they require an anchor chain up to 250 metres long where each individual chain link can weigh up to 200 kilograms! Continue reading
