Fisheries Genetics

Commercial fisheries are facing increasing pressure as a result of increasing public demand due to population growth. Meeting these demands is challenged by a multitude of factors that threaten the growth and long-term viability of many fishing industries, including climate change, pest incursions, disease, and in some cases overexploitation. Hence, there is an urgent need for improved biological and ecological knowledge of fish species, as well as the interactions between biological and physical processes that shape our fisheries, in order to guide future sustainable management.  

Our group works with a range of invertebrate and vertebrate fisheries, undertaking genetic research that improves knowledge of:

  • Assessment of stock structure and patterns of connectivity

  • Recruitment processes (biotic and abiotic) 

  • Adaptive genetic differences among fishing stocks and drivers of selection pressure

  • Species diet composition and abilities to accommodate shifts in resource availability

  • Resilience to environmental stress

  • The genetic basis of commercial traits of interest
