The Maugean skate (Zearaja maugeana) has the most restricted distribution of any species of fish in Australian waters. Its only found in one or two inlets on the remote western coastline of Tasmania in southern Australia. PhD student Kay Weltz has determined that its presence can be detected from DNA in water samples, which means that monitoring the survival of the speices now and in the future can be conducted cheaply and quickly.
Hi my name is Danielle Davenport and I am from Gippsland in country Victoria, Australia. I have recently joined the Molecular Fisheries Laboratory (MFL) as a new PhD student under the supervision of Jennifer Ovenden. Prior to joining the MFL, I completed my undergraduate studies in the marine environment at the University of Tasmania and worked for a time in the aquaculture industry. I recently completed my masters degree in Bioinformatics at the University of Queensland where I became interested in using bioinformatic tools and genetic research to inform conservation and management of marine fisheries. The PhD project with the MFL is one part of a larger collaboration between UQ and the Danish Technical University. The project aims to understand the structure and demographies of white shark populations over time using historical (jaws, bones) and contemporary white shark samples.
Madeline Green (PhD student) is the lead author on a study showing that litters of shark pups can have many fathers. The study compared litters from Scalloped Hammerhead and Grey Reef sharks and found it was more common with Hammerheads. Read more here or look it up Green, M. E., Appleyard, S. A., White, W. T., Tracey, S. R. & Ovenden, J. R. (2017). Variability in multiple paternity rates for grey reef sharks (Carcharhinus amblyrhynchos) and scalloped hammerheads (Sphyrna lewini). 7, 1528.
PhD student Sam Williams will be supported by the Fisheries Research and Development Corporation to attend an international conference and study tour in Canada. The award is for young future leaders in the Australian recreational fishing community. The bursary includes attendance to the World Recreational Fishing Conference in Victoria, British Columbia, Canada and a study tour following the conference. Topics to be explored on the study tour include: allocation decisions in the halibut fishery, intra, inter and international issues regarding salmon management and allocation, habitat enhancement and its relationship with stocking programs, education and empowerment programs for anglers and comparing the Canadian and American recreational fisheries models with Australia. Find out more about Sam's research on black marlin here.

MFL research associate Jess Morgan has been working on pink snapper (Chrysophrys auratus) with colleagues from the Queensland Government. Jess' work has estimated of the number of populations of snapper and how they overlap. This new information is essential for the sustainable exploitation of this popular commercial and recreational species. More information can be found here.
A team of MFL researchers, led by PhD student Ms. Carolina Vargas-Caro, has published new information to assist with the sustainable exploitation of Chilean skates. As a fishery resource, skates are susceptible to overexploitation. They often occur in shallow inshore areas making them easily accessible to fishers. Their rate of reproduction is slow and the number of offspring produced is low. Exploitation rates need to be carefully considered to ensure populations can support seafood production now and in the future. This new work shows there are three genetically-distinct stocks on the Chilean coastline. Spatially-explicit models of population size and effects of harvesting need to match this stock structure to be most accurate.
