On Tuesday, 7th October 2014, the team met to discuss new scientific information coming out of the project. The workshop was held at the Sydney Institute for Marine Science. Here Dean Blower, PhD student at the University of Queensland, explains how the removal of sharks of breeding age is likely to effect estimates of effective […]

Dean Blower and Jenny Ovenden are at the Sydney Institute of Marine Science today. Along with collaborators Vic Peddemors and Paul Butcher from NSW Fisheries and others, Dean and Jenny have been gathering new scientific data to assist the sustainable management of the whaler shark fishery on the eastern Australian coastline.

Laura Taillebois and Jenny Ovenden are part of a project to understand the population structure of species that are popular with recreational fishers. Damien Broderick holds a Black jewfish (Protonibea dicanthus) caught in waters off Darwin (Northern Territory, Australia) by Jenny (right). Laura and Jenny will be combining genetic data with parasite and otolith chemistry information from […]
Congratulations to Tom Kashiwagi who has completed his PhD at the University of Queensland. Tom was supervised by Jennifer Ovenden and Mike Bennett. Tom studied the genetic signature of speciation in two species of manta rays (Manta alfredi and M. birostris). Using a long-term (over 30 years) database of underwater observations on M. alfredi in […]
Today the Environmental Protection Authority in Western Australia rejected the Government’s proposal to reduce the size of shark populations to improve public safety. Read their news release here. Special thanks to Jessica Meeuwig and her team and the 300 scientists who jointly signed the protest letter.

The mitogenome of Zearaja chilensis was published this week by Carolina Vargas-Caro and her collaborators at MFL. Carolina will travel to Chile in October 2014 to work with fisheries authorities there to determine the spatial extent of this and similar species. Download the paper here.

Samuel Williams developed these new microsatellite loci for use with black marlin. This is the second of three planned publications from Sam’s BSc Honours work. Sam was rightly awarded a first class honours for his efforts. Download an early-on-line version of the paper here.
Kay Weltz (PhD student from the University of Tasmania) is working on the development of new genetic markers for research into a rare species of skate. The markers will allow Kay to investigate the number of separate populations of this species, and to understand aspects of their reproductive behaviour. Kay is supervised by Jayson Semmens and Jeremy […]
Pascal Geraghty has completed his PhD thesis at Macquarie University, Sydney. Pascal studied three shark species (dusky shark – Carcharhinus obscurus, , spinner shark – C. brevipinna, and sandbar shark – C. plumbeus). The thesis addresses important questions about the resilience of populations to fishing-induced mortality and the sustainability of the local fishery in inshore waters adjacent […]
The Maugean skate (Zearaja maugeana) is found only estuarine embayments on the isolated western coast of Tasmania in southern Australia. PhD student Ms Kay Weltz (left, shown here discussing DNA results with MFL associate Jess Morgan) is using genetic markers to study the biology of this unique elasmobranch species. Kay is visiting MFL from the University […]
