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 →
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 →
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.

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.

Daniel Swadling is a new PhD student at the University of Wollongong who is embarking on a project to better understand the relationship between temperate fishes and their habitats. He also loves his luderick and drummer fishing using an old school Alvey reel, so he is going to fit in just fine and I sense there will be plenty of fishing adventures in the future. Below is his guest post recapping his honours project and where he is heading with his PhD research.
My name is Daniel, I am a PhD student at the University of Wollongong (UOW) Continue reading →
If you are in Jervis Bay and see someone knee deep surrounded by rays or alternatively sitting staring at rays for hours on end then chances are you are looking at the “mother of rays” otherwise known as Joni – the driving force behind the Stingray Diaries. She’s studying smooth stingrays throughout the Jervis Bay Marine park, in conjunction with Fisheries NSW and gives us a rundown on her research in her guest blog below…

Learning to swim by getting thrown off the end of a busy public wharf on the Hawkesbury River in nothing but a pair of hot pink floaties… Living in a swimsuit and covered in sand every single day of the year… Chucking tantrums when told to come inside after playing on the beach all day because it was dark… At the age of 4, saying with great certainty, “Mum, when I grow up I’m going to be a Marine Biologist.” Continue reading →
