Jess and Jenny updated fisheries stock assessment modellers (George from the Queensland Government; Peter from CARM at UQ) about the spatial extent of populations of commercially harvested shark species in Queensland. Genetic information will guide the extent of the models along the Queensland coast. For example milkshark are likely to be a single population, but blacktip sharks may be two populations. The mathematical models will be used by fisheries managers to ensure shark catches remain at sustainable levels. L - R George Leigh, Jenny Ovenden, Jess Morgan and Peter Baxter.
A new paper from PhD student Pascal Geraghty suggests that large sharks don't move along the coasts as far as expected. Pascal's work shows that spinner sharks (Carcharhinus brevipinna) from Australia are separate to those in southern Africa. There may also be two separate populations in tropical Australian waters.

This project will assist fisheries businesses on the northern coast of NSW to sustainably and profitably harvest shark species. New information will be provided to determine the sustainable total allowable catch of shark. The project began in January 2012 and is set to be completed in 2014.

Meeting participants (R-L) - Vic Peddemors (Principal Investigator - Fisheries NSW), Paul Butcher (Scientist - Fisheries NSW), Jenny Ovenden (Principal Research Fellow – University of Queensland), Dean Blower (PhD candidate – University of Queensland), Shane McGrath (Scientist - Fisheries NSW), Wayne Sumpton (Research Scientist - Queensland Fisheries) and Veronica Silberschneider (Management - Fisheries NSW).
