Increasing opportunity for kingfish in Tasmanian waters

Sightings of yellowtail kingfish in Tasmanian waters have been regularly logged with Redmap since the program began. These records are particularly valuable because they indicate that kingfish from eastern Australia could be on the move south, suggesting that some dedicated scientific research may be necessary to get to the bottom of what’s going on. 

In this article, PhD student and kingfish project leader Curtis Champion describes recently published findings ...

Detecting range-shifting species using their environmental preferences

Curtis Champion is a PhD student at the Institute for Marine and Antarctic Studies (IMAS) and CSIRO Oceans and Atmosphere. Here he explains how we can use species' preferences for specific environmental conditions to measure and monitor the effects of climate change on their distributions.

Mass die-offs - Warm water fish can't handle the cold?

Bite-sized pieces: Redmap Report Card 2016

Australians have shared more than 2100 photos on Redmap of unusual or rare marine life in their local seas. Top-sighted Redmap species include threadfin butterflyfish in NSW, eastern rock lobster in Tasmania and redthroat emperor in WA. More than half of the sightings were submitted by divers. And the community data was used or mentioned in 23 scientific papers! The Redmap Report Card recaps who spotted what where around the ...
