Fish Thinkers six most popular Instagram posts of 2017

At the end of each year I like to put up some customary navel gazing i.e. a review of the Fish Thinkers year. It is a summary mainly as a record for myself as I find it useful to look at our blog and social media stats and see what people are particularly interested in.  Although there is also the odd chance someone else is vaguely interested—since people have brought up parts of the review before, I guess a few people are anyway. Here is the 2017 review: Continue reading

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.

Shopping can be confusing at the best of times, and trying to find environmentally friendly options makes it even more difficult. Welcome to our Sustainable Shopping series, in which we ask experts to provide easy eco-friendly guides to purchases big and small. Continue reading

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

Shark Search Indo-Pacific: finding sharks and conservation solutions in the Big Ocean

Dr Andrew Chin is based at the Centre for Sustainable Tropical Fisheries and Aquaculture – James Cook University and is the current president of the Oceania Chondrichthyan Society. He is also the Programme Director of Shark Search Indo-Pacific, a project that I personally find incredibly interesting and have been following closely. Andrew stopped by Fish Thinkers to give us the inside scoop on Shark Search Indo-Pacific in the guest post below: Continue reading

Using Rockpool Fish Behaviour to Understand why Rockpools are so Species Rich

Blenny

goby

The Cocos frill goby (Bathygobius cocosensis) and the Eastern jumping blenny (Lepidoblennius haplodactylus) dominate intertidal rockpools in south eastern Australia making them ideal species to use when investigating the diversity of rockpool fish communities. Beautiful illustrations by Tilley Wood (Instagram: @tilleymadethis).

Following on from a previous fish thinkers guest post: “Close to home: what drives the distribution of intertidal rockpool fishes?”, University of Wollongong Researchers  Kai Paijmans and Dr Marian Wong  have published new research that offers novel insight into the secretive goings on of rockpool fish communities.

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.
