Detecting and solving fraud in snapper markets

IMG_8227MFL was happy to host a visit by Dr Donna Cawthorn from the Mariani MolEcoLab, School of Environment and Life Sciences, University of Salford, UK. Donna is a Marie-Curie Fellow working on snappers (Lutjanidae), which are the most highly prized and important fisheries resources throughout the warm waters of the Atlantic, Pacific and Indian Oceans. But they are frequent targets of illegal, unreported and unregulated (IUU) fishing and deliberate mislabelling. Donna is conducting the first comprehensive international trade data analysis for snappers and applying cutting-edge genetic techniques to investigate the diversity of species underpinning the global trade.

Stock structure of tropical reef fish – project meeting

NT Fisheries meeting 100428Project scientists from Western Australia, Northern Territory and Queensland are meeting in Brisbane to discuss and synthesise scientific results. New information from genetics, otolith chemistry and parasite has been collected from three important tropical inshore fish species to guide sustainable management into the future. Read more about the project here. L to R: Front Laura Taillebois, Safia Maher, Dave Welch, Di Barton, Christine Dudgeon, Jenny Ovenden. Back; Richard Saunders, Dave Crook, Thor Saunders, Steve Newman and Jon Taylor.

Working with DNA from northern Australian fish species.

Chris and Jenny 150331Christine Dudgeon has started work at MFL on the NT Fisheries project. Chris will be genotyping three inshore reef species following on from work done at Charles Darwin University by collaborator Laura Taillebois and others. Collection of samples for this project have spanned northern Australia from Queensland to Western Australia. Chris runs the "Spot the Leopard Shark" project and is the author of numerous scientific publications on the population genetics and ecology of sharks and rays.

Collaborative sample collection effort underway in Northern Australia

Maningrida and Nhulunbuy women rangersPerhaps more than other fisheries research, projects involving the application of genetics rely on the expertise and cooperation of others to provide samples for analysis. MFL is pleased to work with a diverse team to define the stock structure of key species in northern Australia. In this project, indigenous rangers, fisheries scientists and government experts are working together in the field, with huge flow-on benefits to all. More details can be found on here.

New scientific research on popular recreational fish species in the Australian tropics

JO_jewfish_2Laura 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 the same individuals to get an integrated picture of the stock structure of the Golden Snapper (Fingermark Snapper, Lutjanus johnii), Grass Emperor (Lethrinus laticaudis) and Black Jewfish (Protonibea diacanthus). Go here for project details.
