Opportunities and impacts of range extending scalefish species: understanding population dynamics, ecosystem impacts and management needs
Species-level responses to ocean warming is a priority research area as they underpin the structure and function of marine ecosystems and the productivity of fisheries that operate within them.
There are a number of range extending species that have become increasingly abundant in Tasmanian waters, providing new fishing opportunities for recreational and, to a lesser extent, commercial fishers. Species in this group include Pink Snapper, King George Whiting and Yellowtail Kingfish. While King George Whiting are known to spawn off the north coast it is unclear as to whether the other species have or are likely to become established as self-sustaining populations in Tasmanian waters or simply persist as spill-over from populations that are centered off mainland Australia. If the former is the case, it will be especially important to consider population attributes such as growth, mortality and reproductive dynamics relevant to the Tasmanian populations when developing and refining management arrangements to maximise the opportunities these 'new' species bring.
In addition, the broader ecosystem impacts of such range extending species, including competition with resident species at similar trophic levels, are unknown but could have consequences for other recreationally and commercially important species. Understanding these relationships will have benefits for the assessment and management of the Tasmanian recreational fishery more generally.
Final report
This work set out to quantify the biology and diet of three key range-shifting species in Tasmania with both recreational and commercial fishery value. The project was heavily reliant on engagement from the recreational fishing community and multiple citizen science initiatives, as well as historical data.
The information collected was used in modelling to predict how suitable habitats for each species may shift under future climate change projections. The work also indicated the potential changes to the ecosystem (such as food web) if these species’ ranges were to move.

Capability and Capacity: Navigating leadership pathways in fishing and aquaculture
In a 2019 review of FRDC’s investment in people development, it was noted that significant variability exists across the industry in terms of leadership capability and capacity with most of FRDC investment focused on mid to higher levels of leadership (Lovett). While this past review is comprehensive, it is now 5 years old and pre-dates the ‘black swan’ event of COVID-19 that saw widespread disruptions to the economy, supply chains, and workforce, and has had consequences for leadership capacity and capability needs.
This project will review the current leadership development ecosystem, mapping relevant leadership programs, and identify potential opportunities for a diverse range of industry participants who will benefit from developing leadership capability and skills. Furthermore, acknowledging that leadership capability is not necessarily tied to formal positions of leadership, this project aims to identify different entry points for individual leadership development to ensure accessibility of opportunities. Any potential gaps in accessibility and potential new pathways will be identified. It is imperative that a lack of knowledge of learning and training opportunities to develop non-technical skills or low confidence levels to engage due to unclear entry pathways is not a barrier to any willing participant seeking to enhance their strengths and pursue an interest in making greater contributions that align with industry leadership capacity needs.
Our project combines a review of modern leadership definitions, theories, frameworks and practices, and through stakeholder engagement seeks to identify how these meet the context specific leadership challenges for the wild catch and aquaculture industries. Qualitative and quantitative research will be used to map and evaluate the current leadership development ecosystem for the wild catch and aquaculture sectors, identifying current pathways, recruitment processes, target outcomes, and the value and variety of alumni. Gaps in leadership capacity and capability will be identified and areas for potential changes investigated. Recommendations for improving return on investment in the existing leadership ecosystem will be made, including continuing development or improved integration of post program leaders into the industry. The current project has been designed to provide the breadth and depth of information that leads to practical implications for further industry engagement in leadership capacity and capability development.
