1. Billfish Fisheries
We are collaborating with various stakeholders to collect current data on billfish species. Our work also relies on historical data sources. Our goal is to be able to understand the associated fishery types (artisanal, recreational/sport and industrial) in terms of gears and fishing locations, billfish catches, related biological and ecological parameters, composition and weight, fishing target species, and bycatch species.
2. Spatial and temporal distribution
We use historical tagging combined with current distribution data to understand billfish landings and occurrence hotspots, fishing gear selectivity and effort dynamics.
3. Genetic Stock Structure
We are working with sport fishers operating as members of billfish tagging programs and New South Wales fisheries to collect billfish tissues. Assistance by recreational fishers is valuable as it promotes citizen science, and in turn sustainable catch and release practices enabling non-lethal sampling to be undertaken. We employ the DaRT DD-RAD Sequencing technique to develop Single Nucleotide polymorphisms (SNP’s). SNPs discovered using RAD-sequencing will be used to evaluate both broad- scale genetic structure throughout the Indian Ocean and finer scale connectivity in the WIO.
4. Socio-economic perspectives, Policy and Governance
Our work examines the motivations and perceptions for billfish use, value chain, governance and socio-economic importance to provide comprehensive and effective knowledge for sustainable use and management of billfish species.
