1. Develop a program for ongoing collection of biological samples and data of key range-shifting fish species using citizen science initiatives engaging with the recreational fishing community.

2. Develop geographically discrete life-history parameters for key range-shifting fish species in Tasmania to inform management decisions.

3. Determine the diet composition of key range-shifting fish species to refine parameterisation of an ecosystem model.

4. Utilise the Atlantis ecosystem model framework to predict ecological impacts of increasing abundance of key range-shifting fish species in Tasmania.

5. Develop species distribution models that utilise oceanographic climate change projections to predict the future presence and persistence of the key target species in Tasmania.
